IMPORTANT SAFETY INFORMATION
Please read this manual thoroughly before use and store in a safe place for future reference
WARNING
• Do not exceed the maximum allowable input range of any function.
• Do not apply voltage to multimeter when resistance function is selected.
• Set the function switch OFF when the multimeter is not in use.
• 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
• Improper use of this multimeter 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 multimeter itself for any damage before operating the
multimeter. 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 multimeter 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difcult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speciedbythemanufacturer,theprotectionprovidedby
the equipment may be impaired.

METER FUNCTIONS
DC/AC CURRENT MEASUREMENTS
1. Set the rotary function switch to the 1000A or 400A or 40A ranges.
a. If the range of the measured is not known,
   selectthehigherrangerstthenmovetothe
lower range if necessary.
2. Select AC or DC with the MODE button.
3. Press the trigger to open jaw and fully enclose one conductor to be measured.
4. The clamp meter LCD will display the reading.
WARNING: Ensure that the test leads are disconnected from the meter before making current clamp
measurements.
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 rotary 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 on the 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 rotary function switch to the Ωposition.
3. Select Resistance with the MODE button.
4. Touch the test probe tips across the circuit or component under test.
a. 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 <100, 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. Set the rotary function switch to the Ωposition.
3. Select with the MODE button.
4. Touch the test probe to the diode under test.
a. Forward voltage will indicate 0.4V to 0.7V.
b. Reverse voltage will indicate “OL”.
c. Shorted devices will indicate near 0mV.
d. Open devices will indicate “OL” in both polarities.

CAPACITANCE MEASUREMENTS
1. Set the rotary function switch to the CAP position.
2. Insert the black test lead banana plug into the negative COM jack and the red test lead banana plug
into the positive V jack.
3. Touch the test leads to the capacitor under test.
4. Read the capacitance value in the display.
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.
FREQUENCY OR % DUTY CYCLE MEASUREMENTS
1. Set the rotary function switch to the V position.
2. Insert the black test 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.
TEMPERATURE MEASUREMENTS
1. Set the rotary function switch to the TEMP position.
2. Insert the Temperature Probe into the negative COM jack and the positive V jack,
making sure to observe the correct polarity.
3. Select oC or oF with the MODE button.
4. 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 (about 30 seconds).
5. Read the temperature in the display. The digital reading will indicate the proper decimal point
and value.
WARNING: To avoid electric shock, disconnect both test probes from any source of voltage before
making a temperature measurement.
WARNING: To avoid electric shock, be sure the thermocouple has been removed before changing to
another measurement function.
DATA HOLD AND BACKLIGHT BUTTON
• Press the DATA HOLD button to “freeze” the reading on the indicator.
• “HOLD” will appear when the reading has been “frozen”
• Press HOLD button again to return to normal operation.
NOTE: The HOLD feature will activate when the Backlight is turned on. Press HOLD button again to
exit hold.
• Press the HOLD button for 1 second to turn on the Backlight function.
• Press the HOLD again to turn off the Backlight.
