High Current (A-HI) Mode Calibration
1.
At the FREQUENCY Display, press the
﹀
button to select
(A HI).
2.
At the OUTPUT Terminals, carefully connect a resistive load and connect a
certified, calibrated RMS ammeter, of at least 0.2% accuracy.
3.
The size of the resistive load should be calculated based on the high-current
parameter for your particular FC200 unit, as shown in the following Calibration
Table. Use 100 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-current output reading and will output
approximately 100 VAC.
6.
The external RMS ammeter will display the actual current output. The
CURRENT Display shows the calibration value (see Calibration Table, above).

7.
Adjust the load or the output voltage until the RMS ammeter displays the value
shown in the Calibration Table (above). Please note, the value for your unit will
depend on the model.
8.
At the CURRENT Display, adjust the metered current using the
︿
or
﹀
buttons
until the metered values match.
