Code 12 *T.ADJ 1
First select sensor 1 or sensor 2 for temperature adjustment
(*T.ADJ 1 or *T. ADJ
2)
.
With the process temperature sensor at a stable known temperature, the
temperature reading is adjusted in the main display to correspond.
The calibration is a zero adjustment to allow for the cable resistance, which will
obviously vary with length.
*T.ADJ 2
The normal method is to immerse the sensor in a vessel with water in it,
measure the temperature with an accurate thermometer, and adjust the reading
for agreement.
