2.5.1
In the Offset & Gain fields, the offset and gain registers for both channels are displayed in hexadecimal
and decimal formats. These registers can be modified directly by typing the desired value in the hexadec-
imal display fields. There are two types of offset registers: DC offset and AC offset. The AC Offset register
only affects the RMS register values. The DC & AC offset registers are two's complement numbers whose
values ranges from -1 to +1. The gain register value ranges from 0 to 4.
2.5.2
Offset and gain calibrations can be performed on both the voltage and current channels of the CS5463.
Because the initial values in the calibration registers will affect the results of the calibrations, it is generally
a good idea to software reset the CS5463 before running calibrations. A software reset will reset these
registers back to the default values of zero offset and unity gain. Offset calibration should be performed
before gain calibration to ensure accurate results.
2.5.2.1
The calibration value(s) will automatically update when the calibration is completed.
2.5.2.2
The calibration value(s) will automatically update when the calibration is completed.
The Calibration Window also contains the Power Offset Register display and adjustment. The user can
read and write the value in the power offset (Poff) register.
