To measure Kilowatts and Power Factor in a single
phase 2-wire system
• Set rotary switch to PF/kW without jaws clamping onto any
wire
• If the watt reading is not zero, press the DC A/W ZERO
button once to zero out the watt reading.
• Insert the black test lead into the COM terminal and the red
test lead into the + terminal.
• Connect the black test probe to the neutral conductor and
the red test probe to the hot conductor.
• Using the trigger to open the jaws, fully enclose the hot
conductor within the clamp.
• Release the trigger and be sure that the jaws have closed
completely.
• The power clamp selects the appropriate range based on the
Autoranging table.
• Power Factor (PF) is a calculated value based on the
formula
PF=_______
• The kW value is shown on the main display and the PF
value is shown on the upper display.
• Positive PF (+) indicates an inductive load, while negative
PF (-) indicates a capacitive load.

To Measure Voltage and Frequency
• Set the rotary switch to V/Hz
• Insert the black test lead into the COM terminal and the red
test lead into the + terminal.
• Connect the test probes in parallel with the load or circuit.
• The power clamps automatically selects the proper range.
Note: The “+” sign on the jaw must face the power source for
correct measurement.
