Calibration
10.1
Overview
All Adaptive Power Systems’ instruments are factory calibrated prior to shipment. The
recommended calibration interval for CFS300 Series instruments is one year (every 12
months).
10.2
Hardware Verification Procedure
This section covers the hardware verification procedure for the CFS series power supply. The
hardware verification should be performed prior to the standard calibration. This procedure
should be used to determine if a hardware calibration should be performed. All Tests should
be performed at 60Hz.
If the hardware verification indicates adjustments are needed, proceed to Section
Error!
Reference source not found.
, “
Error! Reference source not found.
”.
If the hardware verification does not indicate that any adjustments are needed, proceed to
Section 11.3, “Software Calibration Procedure”.
10.2.1

Hardware Verification Procedure Steps
To Activate Verification Mode
1.
Press the “0” and “7” keys both while simultaneously turning ON the power source
at the front panel switch.
Adjust Bias Power Voltage for Control Circuits
1.
Note:
The Bias Power voltage for the control board was set at the time of
manufacturing. Under normal use conditions, there should be no need to adjust this
voltage and this procedure is included only for non-routine situations.
2.
Connect the DVM to the “+15V” and “G” points on the “FLY61000” board assembly.
3.
Set the DVM to measure DCV.
