CONFIGURATION MENU SCREENS
Calibration Type
If input 2 is selected as a standard process input, the user can select the cali-
bration type from base; single or 2-point calibration. Select single to apply a
calibration offset across the entire measured range. Use 2-point to enter cali-
bration offsets at both low and high points of the usable range – refer to the
User Calibration details.
Caution:
The default is Base Calibration. For single or 2-point cali-
bration, the user must enter values to adjust the displayed value to
match a known standard or accurate external reading.
Calibration Offset
The single point calibration offset. Limited by the input span, +Ve values add
to, –Ve values subtract from measured input across the range.
Calibration Low Value
The displayed value for the 1st (low) adjustment of 2-point calibration. Choose
a value close to the lowest level used in the application.
Calibration Low Offset
The adjustment value for the 1st (low) point when using 2-point calibration.
+Ve values add to, –Ve values subtract from measured input at this point.
Calibration High Value
The displayed value for the 2nd (high) adjustment of 2 point calibration. Choose
a value close to the highest level used in the application.
Calibration High Offset
The adjustment value for the 2nd (high) point when using 2-point calibration.
+Ve values add to, –Ve values subtract from measured input at this point.

Calibration Reminder
Enable/Disable
Enables/disables the Calibration Reminder shown at start-up (and daily there-
after), if the due date has passed - Recorder version only
Calibration Reminder

Auxiliary Input A Type
Enables/disables the Calibration Reminder shown at start-up (and daily there-
after), if the due date has passed - Recorder version only
Aux A Input Lower Limit
These scale values relate to when auxiliary input A is at the range minimum
& maximum values. They are adjustable between ±0.001 & ±10000. When
auxiliary input A provides a remote setpoint, the scaled input becomes the ef-
fective setpoint (although always constrained within setpoint limits).
Caution:
Take care to scale correctly especially if being used as
the remote setpoint source for both loops.
Aux A Input Upper Limit
Auxiliary Input A Offset
An offset applied to the scaled auxiliary input A value. Adjustable, from +/-
0.001 to 20000 units or OFF, with. +Ve values add, –Ve values subtracted.
Useful in multi-zone setpoint slave applications. Default = OFF.
