Trigger
Press the lever to open the transformer. When the lever is released, the jaws
will close again.
12.
Transformer jaws
Pick up the AC or DC current flowing through the conductor. The "+" marking on
the jaw indicates direction of DC current existing on the conductor being tested
which follows forward and vertically with jaws, and reading shown on display is
positive.

Other Functions
Auto Power off
1. Auto power off: approx. 30 minutes.
2. After auto power off, press any button to restart the meter, and the reading
of measurement will be maintained in the display.
Cancellation Of Auto Power Off Feature:
Press and hold the (RANGE) button while rotating function switch from off to
any position to turn the meter on. The auto power off feature is disabled.
Noto “APO” annunciator is missing from the LCD.
HOW TO MAKE MEASUREMENTS
Before making any measurements read safty precautions. Always examine the
instrument and accessories used with the instrument for damage, contamination
(excessive dirt, grease, etc.) and defects. Examine the test leads for cracked or
frayed insulation and make sure the lead plugs fit snugly into the instrument
terminals. If any abnormal conditions exist, do not attempt to make any
measurements.
Voltage measurements
1. Turn off power to the device under test and discharge all capacitors.
2. Plug the black test lead into the COM input jack on the meter and conne connect
the test lead tip to a grounded point (the reference point for measurement of
voltage).
3. Set the Function/Range switch to the "V / V " position.
4. Plug the red test lead into the V
Ω input jack on the meter and connect the circuit
where a voltage measurement is required. Voltage is al- ways measured in
parallel across a test point.
5. Turn on power the circuit /device to be measured and make the voltage
measurement reduse the range setting if set too high until a satisfactory reading
is obtained.
6. After complating the measurement, turn off power to the circuit / device under
test , dischange all capacitors and disconnect the meter test leads.
WARNING
To avoid possible electric shock, instrument damage and / or equip-
ment damage, do not attempt to take any voltage measurements if the
voltage is above 1000Vdc / 750Vac. 1000Vdc and 750Vac are the
maximum voltages that this instrument is designed to measure.
