Gain
Enter the Gain value for the user calibration.
The Gain value changes the gain factor of the
A/D raw value.
The value entered must fall within the value
range 0 … 65535.
The resolution is 1/8192.
Offset
Enter the Offset value for the user calibration.
The Offset value moves the zero point of the
A/D raw value (offset on the y axis).
The value entered must fall within the value
range −32768 … 32767.
A/D raw value
Raw value of the analog/digital converter. This is a 14-
bit value.
If the channel is deactivated, “N/A” (not available) is
displayed.
The A/D raw value is read cyclically from the I/O
module.
Current [mA]
Display of the calibrated input current in milliamps
(mA).
This is a 32-bit value.
If the channel is deactivated, “N/A” (not available) is
displayed.
The input current value is read cyclically from the I/O
module.
