Software Calibration Procedure
This section covers the software calibration procedure for the CFS series power sources. The
software verification should be performed after any hardware adjustment if any were
needed. Otherwise, it can be performed annually after the Hardware Verification
procedure. This procedure should be used before any software calibration is performed. All
Tests should be performed at 60Hz.
10.4.1
Required Calibration Instruments and Standards
The following equipment is required to perform annual software calibration.
•
High Bandwidth True RMS DVM ( >50kHz) capable of measuring 300Vac
•
0-40 Amp AC True RMS Ammeter
•
4000 W Capable Wattmeter or Power Analyzer
•
A 475kΩ, ¼ watt resistor
•
A 10uF, 115V non-polarized capacitor
•
Power Resistors by Model:
o
CFS108:
12Ω, 1000W
& 100Ω, 100W
o
CFS116:

Software Calibration Procedure
To Activate Calibration Mode
To enter the calibration mode power on the unit while holding the 4 key on the numeric
keypad. When in the calibration mode the display will look as follows:
Use the up or down arrow soft keys to navigate to the parameter that you would like to
calibrate. The parameters available for calibration are Voltage 150.0V, Voltage 300.0 V,
Current xx.xxA, Power xxxxW, and A-Peak xx.xA. The actual values for the Current, Power,
and A-Peak will change according to the model number. For example if you are calibrating
the 4kVA model CFS140, the readings will be Current 2.0A, Current 36.00A, Power 4000W,
and A-Peak 52.0A.
