High-Power (P-HI) Mode Calibration
1.
At the FREQUENCY Display, press the
﹀
button to select
(P HI).
2.
At the OUTPUT Terminals, carefully connect a resistive load and connect a
certified, calibrated RMS power meter, of at least 0.2% accuracy.
3.
The size the load should be calculated based on the high-current parameter for
your particular FC200 unit, as shown in the following Calibration Table. Use 120
VAC for the voltage.
4.
An example calculation is shown on page 6-2 in the Section

5.
At the VOLTAGE Display, press the OUTPUT button. The FC200 unit will
automatically perform a high-power output reading and will output
approximately 100 VAC.
6.
Using the VOLTAGE
︿
or
﹀
buttons adjust the voltage to approximately 120
VAC.
7.
The external RMS power meter will display the actual power output. The
CURRENT Display shows the calibration value (see Calibration Table, above).

Adjust the load or the output voltage until the RMS power meter displays the
value shown in the Calibration Table (above). Please note, the value for your unit
will depend on the model.
