4.2 CALIBRATION PROCEDURE

1.

Remove the front lens. Connect power to the meter,
observing proper wiring procedures.

2.

Connect the precision resistance source to the P3
connector observing proper wiring configuration. 
For 3Ðwire connections, use pins 1, 2, 3, and 4. Refer
to 

Figures 4-1

through 

4-3

.

3.

Apply resistance input as indicated in 

Table 4-1

.

4.

Adjust either the 

ZERO

or 

SPAN

potentiometer as

shown in 

Figure 4-4

.

5.

After adjusting the post, go back and verify both
temperature readings. Repeat step 4 as required.

Refer to 

Table 3-1

and 

Table 3-2

for internal jumper

settings.
