Sensor Calibration Page
The Sensor Calibration Page has parameters which can change the internal calibration
of the temperature sensor input signal. There is a low and high calibration point for both
the control sensor and the high limit sensor. To calibrate the instrument, allow the
control to warm up for at least 30 minutes.
To access the Sensor Calibration Page, enter the Setup Mode (see description earlier in
this manual). Press the Page key until Control Sensor is displayed. Press the Menu
key.
The control may have the optional process value retransmission output feature. The
output is a 1 to 5VDC signal. To calibrate the retransmit signal, the RetOutLo and
RetOutHi values from the Control Page must be known. You may bypass calibrating
the control and high limit sensor input to access only the retransmit calibration by
pressing the Menu key until RetCalLo is displayed (skip steps 4-17).
To re-calibrate the instrument:
