is displayed in hexadecimal. Many of the Modes register bits are reserved or unused. Only the usable bits
are displayed in the Setup window.
2.4.8 Cycle Count / Pulse Output Registers
These fields display the values of corresponding register in both hexadecimal and decimal format. Each
register can be modified by typing a value in the corresponding Decimal Value or HEX: field.
2.4.9 Voltage Sag / Current Fault / Ichanlevel / Emin (Irmsmin) / VFrms / Tsettle /
LoadMIN / Epsilon / Temperature Registers
These boxes display the values of the corresponding register in both hexadecimal and decimal format.
Each register can be modified by typing a value in the corresponding Decimal Value or HEX: field.
2.5 Calibration Windows
The Calibration window is used to display and write to the CS5464 offset and gain calibration registers.
The user is also able to initiate the CS5464's calibration sequences that are used to set the calibration
values. Both AC and DC calibrations can be run for offset and gain, for either the voltage channel or the
current channel, or both simultaneously. The user should refer to the CS5464 data sheet for more details
on calibration.
The Refresh Screen button will update the contents of the screen by reading all the register values from
the part. It is a good idea to press the Refresh Screen button when entering the Calibration window, or
after modifying any registers to reflect the current status of the CS5464.
