Notes:
Option Slot 1 is a fixed Limit Relay output. A Digital Input module, if fitted to Option Slot A
will duplicate the function of the front Reset key . As these functions cannot be
changed, configuration menus are not required.
Alarm parameters marked * are repeated in Setup Mode.
CAUTION:
Process Variable Offset modifies the measured value to compensate for probe
errors. Positive values increase the reading, negative values are subtracted. This
parameter is effectively, a calibration adjustment and MUST be used with care.
