This symbol, adjacent to a terminal, indicates that, under normal use, hazardous voltages may be present
Double insulation

Safety notes

• Do not exceed the maximum allowable input range of any function
• Do not apply voltage to meter when resistance function is selected.
• Set the function switch OFF when the meter is not in use

Warnings

• Set function switch to the appropriate position before measuring
• When measuring volts do not switch to current/resistance modes
• When changing ranges using the selector switch always disconnect the test leads from the circuit under test
• Do not exceed the maximum rated input limits

Cautions

• Improper use of this meter can cause damage, shock, injury or death. Read and understand this user manual before operating the meter
• Always remove the test leads before replacing the battery
• Inspect the condition of the test leads and the meter itself for any damage before operating the meter. Repair or replace any damage before use
• Use great care when making measurements if the voltages are greater than 25 VAC rms or 35 VDC. These voltages are considered a shock hazard.
• Remove the battery if the meter is to be stored for long periods
• Always discharge capacitors and remove power from the device under test before performing Diode, Resistance or Continuity tests
• Voltage checks on electrical outlets can be difficult and misleading because of the uncertainty of connection to the recessed electrical contacts. Other means should be used to ensure that the terminals are not “live”
• If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired

Measurements

**** Read and understand all warning and precaution statements listed Read and understand all warning and precaution statements listed in the safety section of this operation manual prior to using this in the safety section of this operation manual prior to using this meter. Set the function select switch to the OFF position when the meter. Set the function select switch to the OFF position when the meter is not in use.

4.1 AC/DC current measurement
WARNING : Ensure that the test leads are disconnected from the meter before making current clamp measurements.

1. Set the Function switch to the 400 ADC, 40 ADC, 400 AAC or 40 AAC range
2. If the range of the measured is not known, select the higher range first then move to the lower range ifnecessary
3. Press the trigger to open jaw. Fully enclose one conductor to be measured
4. The clamp meter LCD will display the reading.

4.2 AC/DC voltage measurements

1. Insert the black test lead into the negative COM terminal and the red test lead into the positive V terminal
2. Set the function switch to the V position
3. Select AC or DC with the MODE button
4. Connect the test leads in parallel to the circuit under test
5. Read the voltage measurement on the LCD display

4.3 Resistance measurements

1. Insert the black test lead into the negative COM terminal and the red test lead into the positive terminal
2. Set the function switch to the Ω **** •))) CAP position
3. Touch the test probe tips across the circuit or component under test. It is best to disconnect one side of the device under test so the rest of the circuit will not interfere with the resistance reading
4. For Resistance tests, read the resistance on the LCD display

4.4 Diode and Continuity measurements

1. Insert the black test lead banana plug into the negative COM jack and the red test lead banana plug into the positive diode jack

2. Turn the rotary switch to the Ω ****•))) CAP position

3. Press the MODE button until **** appears in the display

4. Touch the test probes to the diode under test.
   Forward voltage will indicate 0.4 V to 0.7 V.
   Reverse voltage will indicate “OL”. Shorted devices will indicate near 0 mV and an open device will indicate “OL” in both polarities.

5. For Continuity tests, if the resistance is < 50 Ω, a tone will sound.

4.5 Capacitance measurements
WARNING: To avoid electric shock, disconnect power to the unit under test and discharge all capacitors before taking any capacitance measurements. Remove the batteries and unplug the line cords..

1. Set the rotary function switch to the Ω ****•))) CAP position
2. Insert the black test lead banana plug into the negative (COM) jack
3. Insert the red test lead banana plug into the positive (V) jack
4. Touch the test leads to the capacitor to be tested
5. Read the capacitance value in the display

4.6 Frequency/duty cycle measurements

2. Insert the black lead banana plug into the negative COM jack and the red test lead banana plug into the positive jack
3. Touch the test probe tips to the circuit under test
4. Read the frequency on the display

4.7 Temperature measurements
WARNING: To avoid electric shock, disconnect both test probes from any source of voltage before making a temperature measurement.

1. Set the function switch to TEMP position
2. Insert the temperature probe into the negative COM and the Positive Jacks, making sure to observe the correct polarity
3. Touch the temperature probe head to the part which temperature you wish to measure. Keep the probe touching the part under test until the reading stabilizes (about 30 seconds).
4. Read the temperature in the display

WARNING: To avoid electric shock, be sure the thermocouple has been removed before changing to another measurement function

4.8 Non-Contact AC voltage measurements

1. Touch the probe tip to the hot conductor or insert into the hot side of the electrical outlet
2. If AC voltage is present, the detector light will illuminate

NOTE: The conductors in electrical cord sets are often twisted. For best results, rub the probe tip along a length of the cord to assure placing the tip in close proximity to the live conductor.
NOTE: The detector is designed with high sensitivity. Static electricity or other sources of energy may randomly trip the sensor. This is normal operation

Functions

5.1 Mode button
To select DC/ACV,OHM/ Diode/Continuity/CAP, °C/°F

5.2 Data HOLD button

1. To freeze the LCD meter reading, press the data hold button
2. The data hold button is located on the left side of the meter (Top button)
3. While data hold is active, the HOLD display icon appears on the LCD
4. Press the data hold button again to return to normal operation

5.3 REL button
For DCA and Capacitance Zero & Offset adjustment.

Battery replacement
