(4) TEMP switch to NORM.

b. Connect TI to autotransformer, using power cable supplied with TI.

c. Connect autotransformer to a 115 V ac power source and adjust for 115 V output.

d. Set POWER switch to ON and allow at least 15 minutes for warm-up.

8. Temperature

a. Performance Check

(1) Connect multimeter to SIGNAL OUTPUT (J2) pin E (+) and pin D (-).

(2) Place probe end of thermometer adjacent to terminals of J2. Wait 10 minutes

for thermometer to stabilize.

NOTE

Constantly check thermometer temperature values to insure

proper millivolt values.

(3) Set TEMP OUTPUT control for 400 C plus value in degrees C as indicated on

thermometer. If multimeter indication is not between 16.14 and 16.65 mV dc, perform

b (1) below.

(4) Set TEMP OUTPUT control for 800 C plus value in degrees C as indicated on

thermometer. If multimeter indication is not between 33.031 and 33.523 mV dc, perform b

(2) and (3) below.

(5) Repeat technique of (4) above at TEMP OUTPUT control settings listed in

table 3. Multimeter indications will be within limits specified.

b. Adjustments

(1) Adjust R40 (fig. 1) for 16.400 mV dc indication on multimeter (R).

(2) Adjust R42 (fig. 1) for 33.257 mV dc indication on multimeter (R).

(3) Repeat a (3) and (4) and b (1) and (2) above, as necessary, for best in-tolerance

compromise.
