sure the jaws are closed and no conductor is
inside the jaw.
2. Press the trigger to the open jaw and fully
enclose one conductor.
NOTE: Only one conductor can be measured
at a time.
3. The LCD will display the reading.
Current Frequency Measurement
1. While in AC current measurement mode and the meter is under test,
press Hz/INRUSH button to enter the Frequency measurement mode.
2. The LCD will display the reading.
3. Press the Hz/INRUSH button again to exit the Frequency
measurement mode.
Inrush Current Measurement
1. While the device to be tested is turned off, set the rotary function
switch to the position.

Capacitance Measurement
1. To avoid electric shock, before taking any capacitance
measurements disconnect power to the unit under test and discharge
all capacitors. Remove the batteries and unplug the line cords.
2. Insert the black test lead into the negative COM terminal and the red
test lead into the positive V terminal.
3. Set the rotary function to the position.
4. Touch the test leads to the capacitor under test.
5. The LCD will display the reading.
NOTE: If the measured capacitor is short-circuited or the capacitance
exceeds the maximum range, the LCD will display "OL". The analog bar
graph is disabled in capacitance measurement mode. When measuring
capacitance >600μF, please allow the meter time to stabilize.
Frequency/Duty Ratio Measurement

Contact Temperature Measurement
1. To avoid electric shock, before taking a contact temperature
measurement disconnect both test probes from any source of voltage.
2. Set the rotary function to the °C/°Fposition.
3. Insert the included Temperature Probe into the negative COM and
the positive V terminals, making sure to observe the correct polarity.
4. Press the SELECT button to change between °C and °F.
5. Place the Temperature probe onto the area being measured. Keep
the probe in place until the reading stabilizes (approx. 30 seconds).
6. The LCD will display the reading.
NOTE: The meter will display "OL" if there is an open input or
a temperature over range. To avoid electric shock, be sure the
thermocouple has been removed before changing to another function.
Non-Contact Voltage (NCV) Detection
1. Set the rotary function to the NCV position.
NOTE: Remove test leads from the meter prior to attempting NCV tests.
Always verify the NCV function on a known live circuit before performing
your tests. Do not use the NCV function if the display does not show EF
when the function switch is turned to the NCV position. If the meter does
not switch on when the NCV mode is initiated, check the batteries.
2. Place the probe near an AC voltage location. If AC voltage is
present, the meter will emit an audible beep, the LCD will display
dashes "---" and the NCV indicator will light up.
NOTE: As the AC voltage signal increases, the frequency of the beeps
and the number of dashes on the LCD screen will increase. Receptacles
in recessed sockets or differences in socket may result in false readings.

Auto and Manual Range
When the meter is rst turned on, it automatically goes into Auto Ranging
mode. This automatically selects the best range for the measurement
being made and is generally the best mode for most applications. For
applications that require a manual range to be set, perform the following:
1. Press the RANGE button. The "Auto" range display indicator will
turn off.
2. Continuously press the RANGE to skip through the available ranges
until the required range is selected.
3. Press and hold the RANGE button for 2 seconds to exit "Manual
Ranging" mode and return to "Auto Ranging".
Relative Mode
Relative mode stores the current measurement reading displayed on the
LCD, resets the meter to zero and maintains the stored measurement
reading as a reference point for all subsequent measurements.
1. Press the REL button to enter relative mode. The indicator will
appear on the LCD along with the relative reading.
2. Press the REL button again to exit relative mode and resume
normal operation.
Note: The meter does not auto range while relative mode is enabled
and does not work under Continuity, Resistance or Diode Test
measurement modes.
Auto Power Off
1. To preserve battery life, the meter is programmed to turn off after
approx. 15 minutes of inactivity.
2. To turn this function off, press and hold the SELECT button while
powering on the meter.
3. If the meter is turned off then back on, the "Auto Power Off" feature
will be enabled again.
