CLAMP
(10) Loosen HOLDING CLAMP (fig. 5) slightly.
(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 9a(1) through 9a(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 digital multimeter power to ON.
(b)
Set digital multimeter to measure dc volts and auto range.
(c)
Connect digital multimeter to UJ1 (fig. 4).
Verify digital multimeter indications vary between 0 2 V dc and 15 2 V dc.
(d)
(e) Wait for READY lamp to stop blinking and remain illuminated.
