SAFETY RULES & WARNINGS

WARNING!!!

This meter is NOT to be used to measure High Energy circuits (power circuitry fused at greater than 4KW, such as distribution circuits, power entrance circuits, etc.) or circuits classified by CE as CATEGORY III (CAT III).

1. Read all instructions in this manual before using this meter. Failure to do so may result in damage to the meter or injury to the user.

2. Prior to using the meter in any situation which could result in injury to the user, in order to verify that the meter is functional and producing a valid reading, test the meter on a circuit(s) known to have potentials equivalent to the potential that is to be measured. For example, before using the meter to determine if an AC power line is energized with 120VAC, test the meter on a line known to be energized with 120VAC. Failure to do so may result in   damage to the meter or injury to the user.

3. Do not use this meter with its case open, or with parts removed. Doing so may damage the meter and/or injure the user.

4. When using this meter in schools and workshops, responsible teachers or skilled personnel must control the usage of this meter. Failure to observe this precaution may result in damage to the meter or injury to the user.

5. Follow the recommendations of any Trade Organizations or Regulatory Agencies whose scope encompasses the use of this meter. Failure to do so may result in damage to the meter or injury to the user.

6. Do not open this meter for maintenance without first disconnecting the test leads from all external circuitry. Failure to observe this precaution may result in damage to the meter or injury to the user.

7. Repairs and maintenance must only be carried out by qualified service personnel or qualified electricians / technicians who know the dangers of, and the safety rules applicable to this type of equipment. Failure to observe this precaution may result in damage to the meter or injury to the user.

8. Always set the meter to the appropriate range or mode before connecting it to the circuitry to be tested. Failure to observe this precaution may result in damage to the meter or injury to the user.

9. Check the condition of the test leads before making a measurement. Do not use the test leads if there is damaged insulation or exposed metal. Failure to observe this precaution may result in damage to the meter or injury to the user.

10. Make sure test leads are properly inserted and seated in the meter’s input jacks. A loose test lead may cause the user to believe that no hazard exists, when in fact, dangerous voltages or currents may be present. Failure to observe this precaution may result in damage to the meter or injury to
    the user.

11. Do not touch the tips of the test leads when making a measurement. Do not touch live circuitry when making a measurement. Failure to observe this precaution may result in damage to the meter or injury to the user.

12. Before using the meter, examine both the meter and the test leads for damage. Do not use the meter if damage (damaged insulation, exposed metal, cracked case, burnt smell, etc.) is evident. Failure to observe this precaution may result in damage to the meter or injury to the user.

13. Insert the test leads in the jacks specified in the instructions for performing particular tests. Inserting the test leads in incorrect jacks can damage the meter and/or injure the user.

14. Do not exceed the maximum voltage or current limitations of the meter (see product specifications). Doing so may damage the meter and/or injure the user.

15. Do not apply voltage or current to the input of the meter when it is set to any of the Ohms Ω ranges. Doing so may damage the meter and/or injure the user.

16. Do not apply voltage or current to the input of the meter when it is set to the Diode Test or Continuity Beeper modes. Doing so may damage the meter and/or injure the user.

17. Do not attempt to measure a voltage source with the test leads plugged into the meter’s mA or 10A jacks. Doing so may damage the meter and/or injure the user.

18. Do not rotate the Function switch with the test leads connected to the circuitry to be tested. Doing so may damage the meter or the circuitry, and/or injure the user.

19. Replace fuses only with exact or equivalent fuses. Do not “bridge” fuses out of circuit. Failure to observe this precaution may result in damage to the meter or injury to the user.

20. Do not apply voltages to the input of the meter which are elevated above the earth ground potential by more than 600V AC/DC. Doing so may damage the meter and/or injure the user.

21. Do not continue to use meter when the “low battery” symbol _ + is displayed. The displayed reading may be in error and lead the user to
    believe that no hazard exists, when in fact, dangerous voltages or currents may be present. Failure to observe this precaution may result in damage to the meter or injury to the user.

22. Use caution when working with voltages above 25 volts AC or 35 volts DC.
    Such voltages may cause a life threatening electrical shock.

23. This meter is not for use by children. Failure to observe this precaution may
    result in damage to the meter or injury to the user.

24. Do not use this meter to make measurements in adverse environments such as rain, snow, fog, or locations with steam, explosive gases or dusts. Doing so may damage the meter and/or injure the user.

25. Do not use meter in condensing atmospheres. That is, do not use meter in conditions where ambient temperature and humidity could cause condensa- tion of water inside of meter. Doing so may cause injury to the user.

26. Do not use the meter if either the meter or the test leads are wet, either from exposure to the weather, or after cleaning the case of the meter. Doing so may cause injury to the user.

27. Do not attempt immediate use of the meter when bringing it from a cold environment to a warm environment. Condensation of water, inside and outside of the meter, may produce dangerous measuring conditions. Allow the meter to warm to room temperature before using. Failure to observe this precaution may result in damage to the meter or injury to the user.

28. Do not modify the meter. Changing the design may make the meter unsafe and may result in injury to the user.

29. Use caution when attempting to evaluate if a dangerous voltage is present. The meter will not read AC voltage if it is set to DC, nor will it read DC if it is set to AC. For example, if the meter is set to 200VDC, it will not measure a dangerous AC voltage, even if the probes are inserted into a household AC wall outlet.

30. Do not touch the metallic portion of one test lead if the other test lead is connected to a live circuit. The current from the live circuit may pass through the meter and appear on the unconnected test lead. Failure to observe this warning may result in user injury.

31. Do not attempt to use meter when no display is present on LCD. Doing so may damage the meter and/or injure the user.

32. Use caution when measuring circuits containing capacitors. Capacitors can store dangerous or lethal levels of electricity, even when the circuitry which they are in has been disconnected from its power source. Some capacitors could source enough energy to damage the meter and/or injure the user.

33. 2.33 Do not use this meter to measure voltages or currents in industrial applica- tions where High Energy circuitry is used. High Energy circuitry is usually regarded as any circuitry capable of supplying over 4000 watts to a load before a safety device (like a fuse) interrupts the circuit. See product specifications for Category II statement.

34. Do not use this meter to measure current in circuits whose open circuit voltage exceeds 250V AC/DC. The meter’s fuses are rated at 250V max. Failure to observe this precaution may result in damage to the meter or injury to the user.

35. When you use the meter to check a high-voltage circuit, do not try to connect both test leads at once. Instead, clip one probe to the neutral or ground lead of the circuit (usually a bare, green, or white wire in AC wiring circuits) using the insulated slip-on Alligator Clips. Then probe for voltages with the other test lead. This helps prevent you from
    accidentally touching a hot wire, since you need to concentrate on only one test lead. Failure to observe this precaution may result in damage to the meter or injury to the user.

36. If there is any doubt about the condition of the meter (i.e. safe vs unsafe), remove the meter from service and secure it in a location that will prevent its unintentional use. Failure to observe this precaution may result in damage to the meter or injury to the user.

37. Do not use the meter if it does not appear to work correctly on all ranges and in all modes. Failure to observe this precaution may result in damage to the meter or injury to the user.

38. Do not use the meter if it has undergone long-term storage under unfavor- able conditions. Failure to observe this precaution may result in damage to
    the meter or injury to the user.

39. Do not use the meter if it may have been damaged in transport. Failure to observe this precaution may result in damage to the meter or injury to the user.

40. Always connect one of the meter’s alligator clips to the low side of a power circuit first. Never clamp onto a hot wire first, (usually red, black, or blue in AC wiring circuits.) If you clamp onto a hot wire first, and touch the other probe, you could receive a shock. Failure to observe this precaution may result in damage to the meter or injury to the user.

41. To avoid damage to the meter and possible user injury, disconnect test leads from test points before changing the function/range. Failure to observe this precaution may result in damage to the meter or injury to the user.

42. Avoid usage near strong magnetic fields (magnets, loudspeakers, transformers, motors, coils, relays, contactors, electromagnets, etc.). The meter may display readings that are in error, causing the user to misinterpret the hazards present. For example, the meter may indicate a low voltage when high voltages are actually present. Failure to observe this precaution may result in damage to the meter or injury to the user.

43. Avoid usage near strong electrostatic fields (high voltage power lines, televisions, computer monitors, etc.). The meter may display readings that are in error, causing the user to misinterpret the hazards present. For example, the meter may indicate a low voltage when high voltages are actually present. Failure to observe this precaution may result in damage to the meter or injury to the user.

44. Avoid usage near strong RF fields (radio or television transmitters, walkie talkies, cellular phones, etc.). The meter may display readings that are in error, causing the user to misinterpret the hazards present. For example, the meter may indicate a low voltage when high voltages are actually present. Failure to observe this precaution may result in damage to
    the meter or injury to the user.

45. Remove the battery when the meter may be left unused for longer than 1 month. Chemical leakage from the battery could damage the meter, leading to user injury.

46. Do not use the meter if there is evidence of chemical leakage from the battery. Leakage could damage meter and lead to injury of user.

47. Observe whether HOLD function is activated. The meter may not show the presence of dangerous potentials when HOLD is activated. For example, if HOLD is applied when the meter is reading zero, and 120VAC is subsequently applied, the meter will continue to read zero. Failure to observe this precaution may result in damage to the meter or injury to the user.

48. Do not attempt to test charged capacitors. Only discharged capacitors may be tested. If you wish to test a capacitor, discharge it using an approved method before connecting it to the meter. Caution: Some capacitors can store dangerous lethal charges. Discharging these capacitors can be dangerous unless an approved method is used. Failure to observe this precaution may result in damage to the meter or injury to the user.

49. Do not use the thermocouple to measure the temperature of objects that are electrically “live”. Failure to observe this precaution may result in damage to the meter or injury to the user.

50. Do not attempt to measure the hFE of a transistor with the meter’s test leads connected. Failure to observe this precaution may result in injury to the user.

51. Do not attempt to measure capacitance with test leads connected to the input banana jacks of the meter. Failure to observe this precaution may result in injury to the user.

MEASUREMENT PROCEDURES

WARNING!!!

Do not use the meter when the low battery annunciator _ + is displayed.This may cause the meter to produce inaccurate readings, and lead the user to believe that no hazard exists, when, in fact, dangerous voltages or currents are present.

Using the HOLD feature

The 9015-A incorporates a convenient HOLD feature. This feature “freezes” the reading in the LCD when the HOLD button is pressed. To release the HOLD, press the HOLD button again.

Note: “H” annunciator appears in the LCD when HOLD is activated.

WARNING!!!

The meter may not show the presence of dangerous potentials when HOLD is activated. For example, if HOLD is applied when the meter is reading zero, and 120VAC is subsequently applied, the meter will continue to read zero. Failure to observe this precaution may result in damage to the meter or injury to the user.

Auto Power Off

The 9015-A has Auto Power Off. This power saving feature automatically turns the meter off 15 to 20 minutes after turning it on…… thereby extending battery life.
DC Voltage Measurement

WARNING!!!

If the magnitude of the voltage to be measured is unknown, always start by setting the meter to the highest range, and then to lower ranges, until a satisfactory reading is obtained. Do not rotate the RANGE switch with the input applied to the meter. If the input voltage is higher than 1000VDC (CAT I), 600V DC (CAT II), or 300V DC (CAT III), do not attempt to measure! Use Caution when measuring voltages above 50V DC.

1. Connect the black test lead to the COM jack and the red test lead to the VOLT / OHM / BEEPER / DIODE / FREQ. “V Ω kHz ” jack.
2. Set the RANGE switch to a V position. If the magnitude of the voltage is unknown, set the RANGE switch to the highest V position. If the input voltage is higher than the previously stated limits, do not attempt to measure!
3. Connect the test probes to circuit being measured. The LCD will display the DC voltage.
4.  If the display indicates overrange, i.e. “1- – -”, disconnect the test probes from the circuit and rotate the RANGE switch to the next higher position. Reconnect the test probes to the circuit and observe the reading on the LCD display. If the RANGE switch is already at the highest position (i.e. 1000 VDC), the input voltage exceeds the measurement capability of the meter and should not be measured.
5. If the displayed value is less than “200” (decimal point not shown), a more accurate reading may be obtained by setting the RANGE switch to a lower range. Disconnect the probes from the circuit and rotate the RANGE switch to the next lower position. Reconnect the test probes to the circuit and observe the reading on the LCD display. If the RANGE switch is already on the lowest position (i.e. 200mV DC), no greater measurement resolution can be obtained.

AC Voltage Measurement

WARNING!!!

If the magnitude of the voltage to be measured is unknown, always start by setting the meter to the highest range, and then to lower ranges, until a satisfactory reading is obtained. Do not rotate the RANGE switch with the input applied to the meter. If the input voltage is higher than 750VAC (CAT I), 600VAC (CAT II), or 300VAC (CAT III), do not attempt to measure! Use Caution when measuring voltages above 30V AC.

1. Connect the black test lead to the COM jack and the red test lead to the VOLT / OHM / BEEPER / DIODE / FREQ. “V Ω kHz ” jack.
2. Set the RANGE switch to a V~ position. If the magnitude of the voltage is unknown, set the RANGE switch to the highest V~ position. If the input voltage is higher than the previously stated limits, do not attempt to measure!
3. Connect the test probes to circuit being measured. The LCD will display the AC voltage.
4. If the display indicates overrange, i.e. “1- – -”, disconnect the test probes from the circuit and rotate the RANGE switch to the next higher position. Reconnect the test probes to the circuit and observe the reading on the LCD display. If the RANGE switch is already at the highest position (i.e. 750 VAC), the input voltage exceeds the measurement capability of the meter and should not be measured.
5. If the displayed value is less than “200” (decimal point not shown), a more accurate reading may be obtained by setting the RANGE switch to a lower range. Disconnect the probes from the circuit and rotate the RANGE switch to the next lower position. Reconnect the test probes to the circuit and observe the reading on the LCD display. If the RANGE switch is already on the lowest position (i.e. 2V AC), no greater measurement resolution can be obtained.

DC Current Measurement

WARNING!!!

If the magnitude of the current to be measured is unknown, always start by setting the meter to the highest range, and then to lower ranges, until a satisfactory reading is obtained. Do not rotate the RANGE switch with the input applied to the meter. If the input current is higher than 10A, do not attempt to measure! Use caution when measuring current in a circuit with voltages above 50 VDC. Do not use meter to measure current in circuits whose voltage exceeds 250V AC/DC.

1. Connect the black test lead to the COM jack. Connect the red test lead to the 10A jack unless it is known that the input current is less than 200mA. If the current is less than 200mA, connect the red test lead to the mA jack.
2. If the red test lead is inserted into the 10A jack, set the RANGE switch to the 10A position. Read the value of the current on the LCD display.
3.  If the red test lead is inserted into the mA jack, set the RANGE switch to the 200mA position. Read the value of the current on the LCD.
4. If the display indicates overrange, i.e. “1- – -”, disconnect the test probes from the circuit and reconnect the red test lead to the 10A jack. Set the RANGE switch to the 10A position, and reconnect the test leads to the circuit. Read the value from the LCD. If the input current exceeds the measurement capability of the meter, as evidenced by a display of over 10 amps, or an overrange display, it should not be measured.
5. If the displayed value is less than “200” (decimal point not shown), a more accurate reading may be obtained by setting the RANGE switch to a lower range. Disconnect the probes from the circuit and rotate the RANGE switch to the next lower position. Reconnect the test probes to the circuit and observe the reading on the LCD display. If the RANGE switch is already on the lowest position (i.e. 2mA), no greater measurement resolution can be obtained.

AC Current Measurement

If the magnitude of the current to be measured is unknown, always start by setting the meter to the highest range, and then to lower ranges, until a satisfactory reading is obtained. Do not rotate the RANGE switch with the input applied to the meter. If the input current is higher than 10A, do not attempt to measure! Use caution when measuring current in a circuit with voltages above 30 VAC. Do not use meter to measure current in circuits whose voltage exceeds 250V AC/DC.

1. Connect the black test lead to the COM jack. Connect the red test lead to the 10A jack unless it is known that the input current is less than 200mA. If the current is less than 200mA, connect the red test lead to the mA jack.

2. If the red test lead is inserted into the 10A jack, set the RANGE switch to the 10A~ position. Read the value of the current on the LCD display.

3. If the red test lead is inserted into the mA jack, set the RANGE switch to the 200mA~ position. Read the value of the current on the LCD.

4.  If the display indicates overrange, i.e. “1- – -”, disconnect the test probes from the circuit and reconnect the red test lead to the 10A jack. Set the
   RANGE switch to the 10 A~ position, and reconnect the test leads to the circuit. Read the value from the LCD. If the input current exceeds the measurement capability of the meter, as evidenced by a reading of greater than 10 amps, or an overrange display, it should not be measured.

5.  If the displayed value is less than “200” (decimal point not shown), a more accurate reading may be obtained by setting the RANGE switch to a lower range. Disconnect the probes from the circuit and rotate the RANGE switch to the next lower position. Reconnect the test probes to the circuit and observe the reading on the LCD display. If the RANGE switch is already on the lowest position (i.e. 20mA), no greater measurement resolution can be obtained.

Resistance Measurement

WARNING!!!

Do not apply voltage or current to the meter when it is set to any of the “Ω” ranges.

1. Connect the black test lead to the COM jack, and the red test lead to the VOLT / OHM / BEEPER / DIODE / FREQ. “V Ω kHz ” jack.
2. Set the RANGE switch to the Ohms “ Ω ” position that is appropriate for the device or circuit to be measured. The LCD display will indicate overrange (i.e. “1 – – -”).
3. Connect the test leads to the device or circuit being measured. Observe correct polarity if appropriate.
4.  If the display indicates overrange, i.e. “1- – -”, rotate the RANGE switch to the next higher position and observe the reading on the LCD display. If the RANGE switch is already at the highest position (i.e. 200M Ohms), the resistance exceeds the value measurable by the meter.
5. If the displayed value is less than “200” (decimal point not shown), a more accurate reading may be obtained by setting the RANGE switch to a lower range. Rotate the RANGE switch to the next lower position and observe the reading on the LCD display. If the RANGE switch is already on the lowest position (i.e. 200 Ohms), no greater measurement resolution can be obtained.

Notes

1. The 2M, 20M, and 200M ranges require several seconds to stabilize.
2.  The 200M range reads 10 LSD high. To obtain an accurate reading, subtract 10 LSD from the indicated value on the LCD.To obtain the most accurate reading on the 200Ω range, short the test leads together and note the “residual resistance” reading. It is typically less than 0.5Ω . Subtract this value from subsequent readings on the 200Ω range.

Continuity Beeper

WARNING!!!

Do not apply voltage or current to the meter when it is set to the Diode Test / Continuity Beeper “ ” range.

1. Connect the black test lead to the COM jack and the red test lead to the VOLT / OHM / BEEPER / DIODE / FREQ. “V Ω kHz ” jack.
2. Set the RANGE switch to the Diode Test / Continuity Beeper “ ” range.
3. Connect the test probes to the device or circuit to be tested.If the resistance of the device or circuit is less than 20 to 100 Ohms, the continuity beeper will sound.

Note: The reading displayed on the LCD is not an accurate indication of the resistance of the device or circuit being measured.
Diode Test

WARNING!!!

Do not apply voltage or current to the meter when it is set to the Diode Test / Continuity Beeper “ ” range.

1. Connect the black test lead to the COM jack and the red test lead to the VOLT / OHM / BEEPER / DIODE / FREQ. “V Ω kHz ” jack.
2. Set the RANGE switch to the Diode Test / Continuity Beeper “ ” range.
3. Connect the test probes to the device or circuit to be tested. To test a simple diode, connect the red test probe to the Anode of the diode and the black test lead to the Cathode (“banded” end) of the diode. The LCD will indicate the voltage drop of the diode. Reverse the connections of the test probes to the diode. The LCD should indicate overrange (“1 – – -”). If the Continuity Beeper sounds when the leads are connected in either direction to a standard silicon diode, the diode is probably shorted.

Note: The reading displayed on the LCD is an accurate indication of the voltage drop of the device or circuit being measured.
Measuring Transistor hFE

WARNING!!!

Do not apply voltage or current to the meter when it is set to the ““hFE ” range.

1. Set RANGE switch of meter to the hFE position. Do not insert test leads into any of the input jacks. Failure to observe this precaution may result in injury to the user.

2. Identify transistor type (i.e. NPN or PNP) and pinout of the transistor to be tested. Insert the leads of the transistor into the meter’s transistor jack at the appropriate locations.

3.  Read the hFE of the transistor on the LCD display.
   Notes:

4. The hFE test is not intended to determine if a transistor is “good” or “bad”. An assumption is made that the transistor is good, and the meter measures the hFE (small signal current gain) of the transistor.

5. For safety purposes, the contacts of the transistor socket are recessed. The leads of transistors removed from circuit boards may not be long enough to make contact in the socket.

6. It may be necessary to hold the transistor, and apply a slight pressure, in order to obtain an hFE reading.

Measuring Temperature

WARNING!!!

Do not attempt to measure the temperature of any surface that iselectrically “live”. Failure to observe this precautionmay result in injury to the user.

1. Remove the test leads from the input jacks of the meter.
2. Set the RANGE switch to the TEMP °F position. Plug the provided K-type thermocouple into the jack on the front of the meter. Observe proper polarity.
3. Read temperature from LCD display.

Measuring Capacitance

WARNING!!!

Do not connect a charged capacitor to the Cx socket of the meter. Doing so may damage the meter or injure the user.

1. Remove test leads from the input jacks of the meter. The test leads cannot be used to measure capacitance and may pose a safety hazard if left connected.
2. Set the RANGE switch to the appropriate Capacitance
3. Insert the capacitor to be measured into the Cx socket.
4. If the display indicates overrange, i.e. “1- – -”, rotate the RANGE switch to the next higher position and observe the reading on the LCD display. If the RANGE switch is already at the highest position (i.e. 20uF), the capacitance exceeds the value measurable by the meter.
5. If the displayed value is less than “200” (decimal point not shown), a  more accurate reading may be obtained by setting the RANGE switch to a lower range. Rotate the RANGE switch to the next lower position and observe the reading on the LCD display. If the RANGE switch is already on the lowest position (i.e. 2nF), no greater measurement
   resolution can be obtained.

Notes
On the 2nF range, the meter will indicate residual capacitance without a capacitor inserted into the Cx socket. This is usually less than 0.020nF. If the capacitor to be measured is too large to insert into the Cx socket, or it is installed in a piece of equipment, the provided Capacitance Extension Lead can be used to make a measurement. Insert the Extension Lead into the Cx socket. Use the clip leads on the other end of the Lead to make connection to the capacitor to be tested Capacitance Extension Lead may introduce error if used on the low capacitance ranges (like 2nF and 20nF). To minimize the error, note the difference in reading with the lead inserted into Cx and with the lead removed from Cx, and when using the lead, subtract the noted difference from the displayed reading.

Measuring Frequency

WARNING!!!

When in the FREQUENCY measurement mode, do not connect input of meter to voltages exceeding 30 volts peak-to-peak. Doing so may produce inaccurate results, and damage the meter or injure the user.

1. Connect the black test lead to the COM jack, and the red test lead to VOLT / OHM / BEEPER / DIODE / FREQ. “V Ω kHz ” jack. 7.13.2 Set the RANGE switch to the 20kHz position.
2. Connect the test leads to the device or circuit being measured.
3. Read frequency on the LCD display

USING THE HOLSTER

A protective holster is provided with the Model 9015-A. This vinyl holster pro- vides a measure of protection from the everyday rigors that products of this type are often subjected to.  Molded into the holster are two holders for the test probes. When not in use, the test leads can be coiled around the meter and the probes snapped into these holders. Take care not to be stabbed with the points of the probes! A built in stand can be flipped out to tilt the meter up to a convenient angle for use on a table top. A flexible loop in the holster allows it to be hung from a hook or nail.

Two different ways to use the holster:

1. Set holster parallel on the table, do not open the tilt stand (see Diagram 1).
2. Flip the stand out to tilt the meter up on a table top (see Diagram 2).

MAINTENANCE

Your Triplett Model 9015-A DMM is a precision measuring instrument and, when used as described in this manual, should not require maintenance.
However, periodic calibration of the meter will insure that it is accurate and per-forming in accordance with its design specifications. A one year calibration inter-val is suggested.
To clean the outside of the meter, use a cloth dampened with a mild detergent solution. Do not use any abrasive cleansers, or chemical solvents that may dam-age the case of the meter.
