Calibration
10.1
Overview
All Adaptive Power Systems’ instruments are factory calibrated prior to shipment. The
recommended calibration interval for CFS100 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 10.3,
“Hardware Calibration Procedure”.
If the hardware verification does not indicate that any adjustments are needed, proceed to
Section 10.4, “Software Calibration Procedure”.
10.2.1
Required Calibration Instruments and Standards
The following equipment is required to perform routine hardware verification.
•
High Bandwidth True RMS DVM ( >50kHz) capable of measuring millivolts DC and
115 VAC
•
A 475kΩ, ¼ watt resistor
•
A 10uF, 115V non-polarized capacitor
10.2.2
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.
Verify High Frequency Noise
2.
Connect the output of the instrument to the DVM.
3.
Set the DVM to measure AC mV.
4.
Set the output voltage to 0V in the HIGH voltage mode and activate the output of
the instrument.
5.
Verify that the reading on the DVM is < 350 mV for the models CFS108 and CFS116
and < 550mV for model CFS140.
