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.
• Do not measure current on a circuit whose voltage exceeds 240V.
• 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 25VAC rms or 35VDC. 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.

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/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
80ADC, 4ADC, 80AAC or 4AAC
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 wire to be measured.
3. If measuring DCA, press ZERO button to
enter the zero reading.
4. The clamp meter LCD will display the reading.
DC/AC 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 with 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 < 150Ω, 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.
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 cap position.
2. Insert the black test lead banana plug into the negative (COM) jack.
Insert the red test lead banana plug into the positive (V) jack.
3. Touch the test leads to the capacitor to be tested.
4. Read the capacitance value in the display
Frequency or % duty cycle measurements
1. Set the rotary function switch to the “Hz/%” position.
2. Insert the black lead banana plug into the negative COM jack
and the red test lead banana plug into the positive V jack.
3. Select Hz or % duty with the Hz/% button.
4. Touch the test probe tips to the circuit under test.
5. Read the frequency on the display.
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 HOLD display icon appears on the LCD.
Press the data hold button again to return to normal operation.
Note: The HOLD feature will activate when the Backlight is turned on.
Press the HOLD key again to exit Hold.
Backlight
Press and hold the HOLD key for >1 second to turn on or off the display backlight function.
Note: The HOLD feature will activate when the Backlight is
turned on. Press the HOLD key again to exit Hold.
ZERO BUTTON
For DCA and Capacitance Zero & Offset adjustment.
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
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
