Calibration Setup
APS-1000 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 APS-1010.
The High Current Calibration Procedure (later in this chapter) specifies an output
voltage of 120 VAC, for all models. From the Table of Calibration Settings, you see
the A HI (A) calibration test current for the (example) APS-1010P is specified at 80 A.
