Safety
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.
- The meter itself for any damage before operating the meter. Repair or replace any damaged before use.
- Use great care when making measurements if the voltages are greater than 25VAC rms or 35VDC. These voltages are considered a shock hazard.
- 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”.

Operation
AC/DC Current Measurements
WARNING: Ensure that the test leads are disconnected from the meter before
making current clamp measurements
1. Set the Function switch to the 1000A AC/DC. 600A AC/DC range
2.1if the range of the measurement is not known, select the higher range first
then move to the lower range if necessary
3. Press the trigger to open the jaw. Fully enclose one conductor to be
measured
4. The clamp meter LCD will display the reading 
4-2.AC/DC Voltage Measurements
- Insert the black test lead into the negative COM terminal and the red test lead into the positive V terminal.
- Set the function switch to the ACV or DCV position.
- Connect the test leads in parallel to the citcuit under test.
- Read the voltage measurement on the LCD display
-3. Resistance Measurements
- .insert the black test lead into the negative COM terminal and the red test lead into the positive terminal
- .Set the function switch to the 2+CAP position
- Touch the test probe tips across the circuit or camponent under test. It is best ta disconnect one Side af the devnce under test so the rest of the circuit will not interfere with the resIstance reading
- For Resistance tests, read the resistance on the LCD display.
4-4.Diode and Continuity Measurements
- nsert the black test lead banana plug into the negative COM jack and the red test lead banana plug into the positive diode jack.
- Turn the rotary switch to the Q0+CAP position.
- Press the M0DE / INRUSH btton until “+ appears in the display.
- Touch the test probes to the diode under test. Forward voltage will indicate 0.4V to .7V Reverse voltage will ndicate OU. Shorted devices will indicate near Om and an open device willindicate OL in both polarities
WARNING: To avoid electric shock, disconnect power to the unit under test and discharge all capacitors before taking any capacitance measurements. Remave the batteries and unplug the line cords.
- Set the rotary function switch to the 2* CAP position.
- Insert the black test lead banana plug into the negative COM jack. Insert the red test lead banana plug into the positive V jack.
- Press the MODE/ INRUSH button change to capacitance measurements.
- Touch the test leads to the capacitor to be tested
- Read the capacitance value in the display.
4-6.Frequency or % Duty Cycle Measurements
- Set the rotary function swtch to the VAC/Hz/% position.
- Insert the black lead banana plug into the negative COM jack and the red test lead banana plug into the positive V jack.
- Select Hz or % duty with the MODE / INRUSH button.
- .Touch the test probe tips to the circuit under test
- Read the frequency on the display.
4-7.Temperature Measurements
WARNING: To avoid electric shock, disconnect both test probes from any source
of voltage betfore making a temperature measurement.
- Set the function switch to TEMP.
- Insert the Temperature Probe into the negative COM and the V jacks, making sure to observe the correct polarity
- Touch the Temperature Probe head to the part whose temperature you wish to measure. Keep the probe touching the part under test until the reading stabilizes labout 30 seconds).
- Read the temperature in the display. The digital reading will indicate the proper decimal point and value WARNING: To avoid electric shock, be sure the thermocouple has been removed before changing to another measurement function.
Button
5-2.RANGE Button
When the meter is first turned on, it automatically goes into AutoRanging.
This automatically selects the best range for the measurements being made and
is generaly the best mode for most measurements. For measurement situations
requiring that a range be manualy selected, perform the following:
- Press the RANGE button. The “Auto Range” display indicator will turn off, The “Manual Range display indicator will turn on.
- Press the RANGE button to step through the available ranges until you select the range you want.
- Press and hold the RANGE button for 2 seconds to exit the ManualRanging mode and return to AutoRanging
5-4.REL /Backtight Button
REL for DCA and Capacitance Zero & Offset adjustment. Long press this button
to turn on the backtight, then long press the turn backlight off.
5-5.Data Hotld / Flashlight Button
- To freeze the LCD meter reading. press the data hold button. The data hold button is located on the right side of the meter top button|. While data hold is actve, the H display ican appears on the LCD. Press the data hold button again to return to normal operation.
- Long press this button to turn on the flashight, then press the turn-off flashlight.
Battery Replacement
- Remove the one rear head screw.
- open the battery compartment.
- Replace the Requires Three AMA 1.5V Battery.
- Re-assemble the meter.
Maintenance
WARNING: To avoid electrical shock, disconnect the meter from any circuit,
remove the test leads from the input terminals, and turn OFF the meter before
opening the case. Do not operate the meter with an open case.
Cleaning and Storage
Periodically wipe the case with a damp cloth and mild detergent; do not use
abrasives or solvents. If the meter is not to be used for 60 days or more,
remove the battery and store it separately. Type K Temperature Probe
Replacement Note: To use a Type K thermocouple probe that is terminated by a
subminiature (Flat blade) connector, a subminiature-to-banana plug adaptor is
required.
