Offset value setting
● Offset value settings are used as a function (zero-point adjustment) to make offset error
adjustments between load devices.
● If the analog input value is "50" when the analog input signal is "0 V", the analog conversion
data is corrected to "0" based on "-50 " as an offset value.
