This is the Calibration Status display. This display shows that no input is selected for calibration.

∙ nonE:

No selection

∙ip1.L: Input 1 (PV1) calibration low-point selected

∙ip1.H: Input 1 (PV1) calibration high-point selected

∙ip2.L: Input 2 (PV2) calibration low-point selected

∙ip2.H: Input 2 (PV2) calibration high-point selected

Use / to select the parameter for the Low Calibration point of Input 1, ‘ip1.L’.

Press

Adjust low-point calibration

This is the display for adjusting the Low Calibration point of Input 1. The lower readout is a live reading of the process value, which changes as the input changes.

Make sure that the calibration source is connected to the terminals of Input 1, switched on and feeding a signal to the controller. It should be set to the desired low-point calibration value. If the lower readout does not show this

value, then use / to adjust the reading to the required value.

Press to return to the ‘ip-List’ header.

To perform the High-point Calibration, repeat the above procedure, selecting ‘ip1.H’ in the ‘CAL.S’ display for

adjustment.

Press three times.

Calibration type

‘USEr’ was selected for the Low-point Calibration, and has remained selected.
