5. OPERATION
5.1 AC+DC Power /. Watt Measurements
1) Connect the test leads to the voltage source in parallel
with the load
2) Clamp on one of the wires to the load.
3) Select AC or DC voltage range and check the voltage
reading.
4) Select the AC or DC current range, and check the
current reading.
5) Select the appropriate Watt range.
6) Read the KW value shown on the LCD.
5.2 AC Current Measurements
WARNING: To avoid electric shock, disconnect the test leads from the meter before making current
measurements.
1) Set the Function switch to the 400A AC range.
2) Press the jaw trigger and clamp around a single conductor fully enclosing it. Do not allow a
gap between the two halves of the jaw.
3) Read the ACA value on the LCD.
5.3 DC Current Measurements
WARNING: To avoid electric shock, disconnect the test leads from the meter before making current
measurements.
1) Set the Function switch to the 400A DC range.
2) Press the DCA zero key to null the meter display.
3) Press the jaw trigger and clamp around a single conductor fully enclosing it. Do not allow a
gap between the two halves of the jaw.
4) Read the DCA value on the LCD.
5.4 AC Voltage Measurements
WARNING: To avoid electric shock or damage to the meter, do not make any voltage
measurements that exceed the maximum specified.
1) Set the Function switch to the VAC position.
2) Insert the test leads to the meter as follows: Red lead to “V,W,Hz” terminal; Black lead to the
COM input.
3) With the pointed end of the test leads measure voltage. Remember that voltage
measurements are made in parallel with the device/circuit under test.
4) Read the ACV value on the LCD.
