(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.
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.
