Calibration Setup
APS-3000P 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-3030P.
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-3030P is specified at 80 A
per phase.

For 100 VAC and 80 A, each leg of your 3- phase load bank should have a resistance of
The power handling capability of each resistive leg of the test load must be at least
