Operation
NOTICES: Read and understand all warning and precaution statements listed 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 is not in use.
AC 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 400 or 200A or20A or
2A range. If the range of the measured is not known,
select the higher range first then move to the lower
range if necessary.
2. Press the trigger to open jaw. Fully enclose one conductor
to be measured.
3. The clamp meter LCD will display the reading.
AC/DC Voltage Measurements
1. Insert the black test lead into the negative COM terminal and the
red test lead into the positive Vterminal.
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.
Resistance and Continuity 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 •))) Ωposition.
3. Use the multifunction MODE button to select resistance.
4. 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.
5. For Resistance tests, read the resistance on the LCD display.
6. For Continuity tests, if the resistance is < 120Ω, a tone will sound.
Diode 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 •))) 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 0.4V to
0.7V. Reverse voltage will indicate “OL”. Shorted devices will indicate near 0mV
and an open device will indicate “OL” in both polarities.
Data Hold
To freeze the LCD meter reading, press the data hold button. The data hold button is located
on the left side of the meter (top button). While data hold is active, the DH display icon appears
on the LCD. Press the data hold button again to return to normal operation.
MAX Hold
To hold the highest reading on the LCD, press the MAX hold button. The MAX hold button is
located on the left side of the meter (bottom button). The meter reading will not change as
readings change, rather it will only display the highest reading encountered since the MAX hold
button was pressed. Press the MAX hold button again to return to normal operation.
Manual Ranging
The meter turns on in the autoranging mode. Press the Range button to go to manual ranging.
Each press of the range button will step to the next range as indicated by the units and decimal
point location. Press and hold the Range button for two seconds to return to autoranging.
Manual ranging does not function in the AC Current, Diode and Continuity check functions
Backlight
The backlight function illuminates the display and is used when the ambient light to too low to
permit viewing of the displayed readings. Press the button for one second to turn the
backlight on and press the button a second time to turn the backlight off.
Battery Replacement
1. Remove the one rear Phillips head screw
2. Open the battery compartment
3. Replace the Requires two “AAA” batteries (UM4 R03)
4. Re-assemble the meter
