MAKING MEASUREMENTS

Preparation & Caution Before Measurement

1. Wait 10 seconds after turning on the meter before making a measurement.
2. The rotary switch should be set to the function that you want to use before connecting the probes to the device being tested. Be sure to remove the test leads from the equipment being measured before switching the rotary switch to a new function.
3. If the meter is used near equipment that generates electromagnetic interference, the display may be unstable or indicate incorrect measurement values.
4. Inspect the test leads periodically for breaks in the insulation or the wire. Make a continuity check whenever in doubt. Replace leads if found defective.

Diode and Transistor Test Measurements
The special Diode Test Function # allows relative measurements of forward voltage drops across the diode and transistor junctions. This function also permits the measurement of in-circuit semiconductor junctions.

Diode Check
For models AM-17 and AM-18, make sure the meter is in the “DC” mode. Failure to do this may result in erroneous reading.

1. Set the rotary switch at (# AM-16), (# •9 AM-17, AM-18):
2. Connect the black test lead to the “COM” terminal and the red test lead to the (VS AM-16), (VS AM-17, AM-18) terminal.
3. Connect test leads to the diode. Red to band end, black to other end. The forward voltage drop of a good silicon diode is typically 400v to .900v. If the diode under test is defective on “.000” (AM-16) or “000” (AM-17 & AM-18) indicates a short circuit. An approximate 1.5v (AM-16) or 2.6v (AM-17 & AM- 18) indicates a nonconducting or open state.
   Reverse check of the diode (reverse test leads). A good diode will indicate approximately (1.5v on AM-16) or (2.6v on AM-17 & AM-18). If the diode under test is defective, a lower value or zero is displayed.

Continuity Test
For models AM-17 and AM-18, make sure the meter is in the “DC” mode. Failure to do this may result in erroneous reading.

1. Connect the red test lead to the input terminal (VS # AM-16) or (VS * AM-17 or AM-18). Connect the black test lead to the “COM” input terminal.
2. Set the rotary function selector to (• for AM-16) or ( • for AM-17 or AM-18).
3. Connect the test leads to the circuit to be measured. The continuity buzzer will sound if the circuit resistance is less than (3800 AM-16) or (255 AM-17 & AM-18).

Voltage Measurements

Do not apply more than 600 VDC or 600 VAC RMS to input. Do not apply more than 600 volts between any input terminal and earth ground. Exceeding these limits creates a shock hazard and may damage the instrument.

1. Connect the red test lead to the (VS AM-16), (VS AM-17 & AM-18) input terminal. Connect the black test lead to the “COM” input terminal.
2. Select AC or DC. AM-16, move the selector switch to “V” or “V-“. AM-17 and AM-18, move the selector switch to “y*” and push the AC/DC switch. Note: “AC” annunciator is displayed in the LCD when AC has been selected.
3. Connect test leads to the device to be measured.
4. When the input is “OVERRANGED” the MSD of the LCD flashes and the three least significant dig- its (LSD) are set to zero. (AM-16 also buzzes a noncontinuous 2 kHz tone).
5. WARNING : DO NOT EXCEED 600VDC or 600V RMS AC limits as stated in the specifications.

Current Measurement (AM-18 only)

DO NOT exceed the current rating of current ranges. If the range is not known, start at a high range.

1. Connect the red test lead to the mA or 10A terminal. Connect the black test lead to the “COM” terminal.
2. Set the function selector switches to the appropriate range. Select AC or DC as required by pushing the AC/DC button.
3. Connect the test leads in series to the load.

Input Jack Alarm (AM-18)

A beep will sound if the test lead is connected to the mA or 10A input terminal. However, the rotary switch is not in the mA or 10A positions.
WARNING : DO NOT apply a voltage between mA/10A and COM terminals.
Capacitor Measurement (AM-17 & AM-18)

CAUTION:

1. Fully discharge any capacitor to be measured.
2. Observe polarity when testing polarized capacitors.

For models AM-17 and AM-18, make sure the meter is in the “DC” mode. Failure to do this may result in erroneous reading.

1. Connect the red test lead to the “VS? *” input terminal: Connect the black test lead to the “COM” input terminal.
2. Select the capacitance range you wish to use.
3. Connect the test leads to the capacitor to be measured.

NOTE 1. Make sure that the display shows DC voltage mode. Not AC voltage mode.
NOTE 2. Use the “OFFSET” button to subtract any stray capacitánce.

Resistance Measurement (AM-16 ONLY)

See “PRECÁUTIONS” and “CAUTIONS” on pages 3 and 4

1. Connect the red test lead to the “VS *” terminal. Connect the black test lead to the “COM” terminal.
2. Set the rotary selector to “” position to measure resistance up to 20MS.
3. Connect test leads to the circuit.
   NOTE : Ensure the circuit under test contains NO VOLTAGE.

Resistance Measurement (AM-17 & 18)
See “PRECAUTIONS” and “CAUTIONS” on pages 3 and 4

1. Connect the red test lead to the “VS * ” terminal. Connect the black test lead to the “COM” terminal.

2. Set the rotary selector to ” position to measure the resistance of up to 2MS. Set the rotary selector to 20Ml position to measure resistance between 2m% and 20Ms.

3. To measure in-circuit resistance shunted by a semiconductor junction, push the “O/LPS” button. “LP” annunciator should come on in the LCD.

4. Connect test leads to the circuit.
   NOTE : Ensure the circuit under test contains NO VOLTAGE.

5. When measuring resistance less than 2002, select the 2002 range then short test leads together (before making measurement) and push the “OFFSET” button.
   This will subtract the resistance of the test leads from the actual circuit measurement.

USING ACCESSORIES WITH THE AM-16, AM-17, and AM-18
High Current Measurement with AC Clamp-On Transducers
AC can be measured using a clamp-on current transducer available as an accessory – Model A663-4B for 0-300 amps AC; model A664-4B for 0- 1000 amps AC.

1. Select the 2V AC range.
2. Plug the leads of the transducer into the “COM” and the “VD” jacks of the AM-16, AM-17 and AM- 18.
3. Clamp the current transducer around a single conductor.
4. Read the display directly using the conversion of 1mV = 1 amp e.g. If the instrument is in the 2V range and the display is showing 0.976, ignore the decimal point and interpret the reading as 976 amps.
5. Transducers are calibrated to give an output of 1mV/1 amp AC from 45-500Hz based on sinusoidal waveforms.

Note: The AMPTRAN® 50:1 transformers (models CT50-1 and CT50-2), the Deca-Tran® 10:1 transformer (model A50-1), and the Energizer line splitter (model A-47L) may be used with the A663-4B/A664-4B transducers to further expand the current measuring capability of the AM-16, AM-17 and AM-18 .
Example – Reading is .600, drop decimal point and multiply by 50; 600 x 50 = 3,000 amps.

The Amptran® CT50-1 has a maximum rating of 6,000 amperes intermittent duty and 5,000 amperes continuous duty. The CT50-2 has a maximum rating of 3,600 amperes intermittent duty and 3,000 amperes continuous duty. The Deca-Tran® A50-1 has a maximum rating of 1,200 amperes intermittent duty and 600 amperes continuous duty. The Energizer A-47L has a maximum rating of 20 amperes intermittent duty and 15amperes continuous duty.
Note : Accuracy of reading on the DMM is the accuracy of the AM 16, AM 17 or AM-18 plus the accuracy of each transducer.
High Current Measurement with AC/DC Clamp-On Transducer CT-600 and AM-16, AM-17, and AM-18 AC or DC can be measured using the current transducer model CT-600 AC/DC

DC

1. Select 2 volt DC range on AM 16, AM-17 or AM-18.
2. Plug the black lead of the CT-600 into the “COM” jack and the red lead into the “VO # * ” jack.
3. Turn the transducer on by sliding the range switch to either the 100 amps or 600 amps position.
4. When measuring DC amps, zero adjusts the output of the transducer. Using the AM-16, AM-17 or AM-18 as a readout device, rotate DCA zero and adjust until a zero or close to zero reading is achieved.
5. Clamp the jaw of the transducer around the conductor, centering it as accurately as possible.
6. Read display on AM-16, AM-17 or AM-18 using the conversion on the front panel of the transducer. i.e.
   For 100 Amp range, 1 Amp equals 10m V and for the 600 Amp range, 1 Amp equals 1 mV.
   Note : The accuracy of the reading on the DMM is the accuracy of the AM-16, AM-17 or AM-18 plus the Accuracy of the CT-600. Refer to the instruction booklet of the CT-600 for its accuracy.

AC can be measured in the same fashion, select the 2V AC range on the AM-16, AM-17 or AM- 18 and follow the above steps.
For better resolution, the 200mV DC range can also be selected on models AM-16, AM-17 and AM-18 when using an accessory.

Temperature Measurement with AM-16, AM 17 and AM-18

See “PRECAUTIONS” and “CAUTIONS” on pages 3 and 4
Temperature from -50°F to 300°F or -55°C to 150°C is possible with the temperature accessory model TMA-1. The following probes available only from Amprobe are used in conjunction with the TMA-1; TPIF – Fahrenheit Immersion Probe; TPSF – Fahrenheit Surface Probe; TPAF – Fahrenheit Air Probe; TPIC – Centigrade Immersion Probe; TPSC – Centigrade Surface Probe; TPAC – Centigrade Air Probe.

1. Install the battery and connect the appropriate probe to TMA-1 as per its operating instructions.
2. Select either the 200mV DC or 2V DE range on the AM-16, AM-17 or AM-18.
3. Insert banana plugs from model TMA-1 observing polarity into the jacks of AM-16, AM-17 or AM-18. (“+” from TMA-1 to “VS# + “jack. “_’ from TMA-1 to “COM” jack.
4. Insert temperature probes into the medium to be tested.
5. The AM-16, AM-17 or AM-18 should now be indicating a mV reading equal to the temperature being measured. i.e. 72mV = 72″

Note : For resolution and accuracy, refer to the operating instructions of model TMA-1. The accuracy of reading on the DMM is the accuracy of the AM-16, AM-17 or AM-18 plus the accuracy of the probe.

Power Measurements with AW-80/AW-81 and AM-16, AM-17 and AM-18

• Measure kilowatts
• Measures AC amperes
• Determine KVA and Power Factor

Power (KW) single phase or AC can be measured using the model AW-80 or AW-81 Watt/Amp Transducer available separately as an accessory.
Model AW-80 ranges 0-19.99/199.9KW with voltage inputs up to 240 VAC (+10% max) and current inputs of 0-150/1000 Amps AC. Model AW-81 ranges 0-40/400KW with voltage inputs of 208 to 550 VAC (+10% max) and current inputs of 0-150/1000 Amps AC. Both units may also be used to measure current 0-1000 Amps AC (50-60 Hz). For complete instructions, see the separate AW-80/81 operating instructions booklet, Pt. No. 981759.

Note: The accuracy of the reading of DMM is the accuracy of AM-16, AM-17 or AM-18 plus the accuracy of the power transducer. Refer to the operating instructions of the AW-80/81 for correct accuracy.

High Voltage Measurement
15K VAC/DC with AM-16, AM-17 and AM-18

1. To use accessory high voltage probe HV-2 with the AM-16, AM-17 or AM-18, unscrew the handle from the main probe and insert resistor model HVR-4 or HVR-41 (not supplied with probe) with the spring on the resistor towards the handle.
2. Screw the handle back onto the probe.
3. Move the rotary switch to the volts position, and select AC or DC.
4. Using the range key, select 20 volt range.
5. Plug the black test lead into the “COM” jack on the meter, and connect the red HV-2 probe in the “V” jack.
6. Take the black lead and ground it.
7. With your hand behind the protective disc on the handle of the probe, touch the probe tip to the circuit under test.
8. Take the reading and multiply by 100.
