value.
NOTE: The Meter is designed for
measurement in single - phase systems. It
is possible to measure in a three - phase
system by creating an artificial neutral
point by using a three phase adapter.

4.6 Measuring power factor

WARNING:
VOLTAGE OF AC VOLT RANGE IS 750V
RMS. DO NOT ATTEMPT TO MEASURE
ANY VOLTAGE THAT EXCEEDS 750V RMS
TO AVOID ELECTRICAL SHOCK HAZARD
OR DAMAGE TO THE INSTRUMENT.
1. Put the Meter in the COS range.
2. Connect the black and red test
leads to the COM and V terminals
respectively.
3. Clamp the jaws around the current
carrying conductor ensuring a good
contact between the closing faces of
the jaws.
4. Apply the test leads to the circuit
under test. (See figure 4.5).
5. Read the displayed value.
A time lag / lead power factor is
indicated on the display by – and +
signs (of the upper part ) as well as
by "Ind" and "Cap" letters (of the
lower part).
4.7 Measuring AC Voltage
1. Put the Meter in the V range.
2. Connect the black and red test
leads to the COM and V terminals
respectively.
3. Apply the test leads to the circuit
under test.
4. Read the displayed voltage.

4.8 Measuring AC Current

CAUTION: MAXIMUM INPUT CURRENT
IS 700A RMS. BEFORE SELECTING THE
CURRENT MEA-SUREMENT FUNCTION

MAXIMUM
INPUT
ENSURE THAT THE TEST LEADS ARE
DISCONNECTED FROM THE INSTRUMENT.
1. Put the Meter in the A range.
2. Clamp the jaws around the current
carrying conductor, ensuring a good
contact between the closing faces of
the jaws.
3. Read the measured current.

4.9 Integrating Energy

WARNING:
VOLTAGE OF AC VOLT RANGE IS 750V
RMS. DO NOT ATTEMPT TO MEASURE
ANY VOLTAGE THAT EXCEEDS 750V RMS
TO AVOID ELECTRICAL SHOCK HAZARD
OR DAMAGE TO THE INSTRUMENT.
1. When the ENERGY pushbutton has
been pressed, the Meter defaults in
the true energy integrating mode
and time stamping mode (ENERGY,
KW.h,: and AUTO displayed).
2. Connect the black and red test
leads to the COM and V terminals
respectively.
3. Clamp the jaws around the current
carrying
conductor
ensuring a good contact between the
closing faces of the jaws.
4. Apply the test leads to the circuit
under test and press the ENERGY
button to scroll through the true,
apparent, and reactive energy value.
The elapsed time between the last
value and the start of the integration
is shown in the upper display.
5. Press and hold the ENERGY button
for two seconds to exit Energy
Integrating mode. See 3.2 Operating
State Diagram for more information.
