Calibration Setup
FC200 calibration is straightforward. However, you must use the appropriate
calibration instrumentation and text fixtures. In addition to test cables and connectors,
you will need:
RMS Voltmeter,
±
0.2%, at least 300 VAC
RMS Ammeter,
±
0.2%, (See Calibration Settings Table for your APS model)
Restive Load Bank, Calculated for your APS model (See following Example)
How to Calculate the Size of the Test Load (Example)
For an example, suppose your system is an FC210.
The High Current Calibration Procedure (later in this chapter) specifies an output
voltage of 100 VAC, for all models. From the Table of Calibration Settings, you see
the
A HI (A)
calibration test current for the (example) FC210 is specified at 8.00 A.
For 100 VAC and 8.0 Amps, your load should have a resistance of 12.5 ohms.
