9

Calibration consists of two parts:

1.

 

Calibration of the A/D converter, using the set up shown in Figure 3.

2.

 

Reference junction calibration, using the ice bath test set up shown in Figure 2.

To calibrate the A/D portion of the thermometer, follow these steps:

1.

 

Connect the calibrator to the T1 input of the thermometer using copper (non-
thermocouple) wire and a copper thermocouple connector. Refer to Figure 3 for
proper equipment connections.

2.

 

Turn the thermometer on, with a small, blunt probe, press the calibration button
located on the back and in the center of the thermometer. Refer to Figure 4.
