6. The calibration command is sent to the device after a delay of 10 seconds. The delay is
introduced by the GUI to allow the device to settle with the specified input. During offset
calibration, the device enters the Calibration mode in which all sensors are disabled, and
the data recording is paused.

7. After the offset calibration is done, the system prompts the user for confirmation to
perform a low gain calibration.

TX-AFE:
•
For Voltage/mA loop/DC calibration, the device proceeds for only low gain calibration
•
For Current/External Clamp CT, the device proceeds for low gain as well as high gain
calibration.
HIA-AFE:
•
In HIA-AFE, all channels have only one gain calibration.
