2.3.4.4 Sensor Offsets (Figures 48 - 49)
These screens allow the control values of the analog input points to be
adjusted if calibration shows these devices to be inaccurate. The range of
these offsets is -9.9 to 9.9. Care must be used when applying an offset to an
analog value as erratic operation can result. To modify the offsets, press the
ENTER
key until the desired offset is selected and use the arrow keys until
the desired setting is shown. Press the
ENTER
key to accept the offset value.
To return to the SERVICE MENU, press the
