Select High-point Calibration

This is the Calibration Status display, again.

Use / to select the parameter for the High-point Calibration of Input 1, ‘ip1.H’.

Press

Adjust High-point Calibration

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

Feed the desired high-point calibration signal to the controller, from the calibration source. 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 protect the calibration against unauthorised adjustment return to Operator level and make sure that the calibration parameters are hidden. Parameters are hidden using the ‘Edit’ facility described in Chapter 3.

To perform a User Calibration on Input 2, proceed as with Input 1 above, except that when ‘CAL.S-nonE’ appears,

press / until ‘CAL.S-iP2.L’ is obtained, then proceed as with Input 1. Repeat the procedure for ‘iP2.H’
