STEP 4:<br />
INSTALLATION AND CALIBRATION<br />
Measure the ambient temperature around the point at which the thermocouple inputs are<br />
shorted. Adjust R23 so that the displayed reading is equal to the measured ambient<br />
temperature.<br />
STEP 5:<br />
Apply an input voltage to thermocouple input 1 corresponding to 1300 oC for a PtRh 6%,<br />
10% and 13% thermocouple or 1100 oC for a Platinel II or type K thermocouple. For type B<br />
an exception has to made. Because of the less voltage under 400 0C, the adjustment for 0 can<br />
not be done by ambient temperature, but needs to be done by 400 0C.<br />
