Temperature Measurements
To measure the Detector and Heater Block temperatures, you will need a FLUKE Model 51 K/J
thermometer or equivalent.
To measure Detector and Heater Block temperatures, proceed as follows:
(1)
Open the door of the upper purged enclosure.
(2)
Next, loosen and remove the four two thumb screws that hold the Valve Driver Board.
(3)
Carefully edge the Valve Driver Board off the holding screws. Do not disconnect the Valve
Driver Board from the cable; merely let the board rest face down, secured by the cable.
(4)
Locate the two Type J thermocouples. They are marked #1 (Detector) and #2 (Heater Block).
