Calibration
11.1
Overview
All APS products ship with factory calibration. No additional calibration is required when first
received.
11.2
Calibration Interval
The recommended calibration interval for these loads is one year (12 months). Routine annual
calibration can be performed by most calibration labs that have low frequency measurement
and power calibration capabilities. Alternatively, the load can be returned to the manufacturer
to obtain a factory calibration.
11.3
Calibration Coefficients
The 44M04 mainframe requires no calibration but the 41L, 42L, 41D and 42D load modules do.
All calibration is performed through software. No manual internal adjustments have to be made
as part of routine calibration.
Calibration coefficients for the following parameters and functions are stored in non-volatile
memory:
Parameters

Calibration Procedures
Certified calibration labs may request a copy of the calibration manual for the relevant load
model by contacting the nearest Adaptive Power Systems company location. Refer to Section 1,
“Contact Information”.
