2.3.5 POST TEMPERATURE SENSOR CALIBRATION
Perform the post temperature sensor calibration as follows using the test
connector set referenced in Section 1.1. The display screen calls for connecting
specific resistances to the X44 (NTC-POST) connector position on the
distribution panel (See Figure 1, pg. 5) for each test. The test connectors contain
resistors which are the closest 1% tolerance resistor available to these values. In
the following procedure, each test connector is identified by the number marked
on its cover.
From the Calibrate Sensors screen, select the Post Temp Sensor screen
button. The screen will change to the following:
1. Remove the distribution board cover from the back of the machine.
Unplug the X44 (NTC-POST) connector from the distribution board.
Connect test connector 34 (6.808K) into X44 (NTC-POST) connection
on the distribution board.
Wait for the Post-Temperature Reference data box to stabilize.
Press the [CONFIRM] key to save the data. The screen will change.
