(11) Increase pressure on thermocouple No. 2 to produce a slight bow in
thermocouple wire by sliding laboratory clamp forward (toward TI) in holding clamp, then
tighten holding clamp (fig. 5).
(12) Repeat technique of steps 9 a (1) through 9 a (3) (e) and record values on "MRT
Target Temperature Worksheet". Temperature error will be between 0.45 and 0.45 C; if
not, perform b (2) below and repeat this step.
(13) Deenergize and disconnect all leads.
(14) Perform steps in paragraph 10 for final procedure.
b. Adjustments
(1) Perform steps (a) through (f) below:
(a) Set multimeter power to ON.
(b) Set multimeter to measure dc volts and auto range.
(c) Connect multimeter to UJ1 (fig. 4).
(d) Verify multimeter indications vary between 0 2 V dc and 15 2 V dc.
(e) Wait for READY lamp to stop blinking and remain illuminated.
(f) Verify multimeter indication is 15 2 V dc.
(2) Perform steps in (2) (a) through (f) below:
(a) Set TI ON/OFF switch to OFF position.
(b) Remove large cover plate (fig. 2).
(c) Ensure ON/ALIGN switch is set to ON.
CAUTION
Disconnect ac power cable from TI before changing dip switch
settings and reconnect TI to ac power cable after changing dip
switch settings.
NOTE
Ensure dip switch 1, A and B are set to ON. Ensure dip switch
2, C and D are set to ON. Refer to figure 9 for example of
settings.
(d) Refer to calculated temperature error for BAR target recorded on BAR
Target Temperature Worksheet or for MRT target recorded on MRT Target Temperature
Worksheet and set dip switch 1 and dip switch 2 (example in figure 9) to indicate
temperature error C as indicated in table 4 (R).
