The following diagram illustrates the conversion characteristic:

The conversion values are given by the formula: Raw digital value:=4095 * Ix/20

Ix: Input current value (mA)

According to the formula, a 4mA input is converted to: Raw digital value=4095*4/20 = 819

This is the value setting for SSL.

A 20mA input is converted to a raw reading of 4095. This is the value setting for SSH.

SCOM-100 physical scale values are limited to integer values between -100,000 and 100,000. It is reasonable to select the physical scale in the range of 0 to 10,000 mBar to gain a better resolution.

The configuration command would then be:
