Repeat steps 15 and 16 until the adjustments are no longer required.
19.
Press the “X” to exit the menu.
20.
Press the green “√” to save the calibration settings.
NOTE:
If the settings are not saved at this point the new calibration parameters will
be lost. The settings will default back to the original settings prior to
calibration.
High temp models will required a calibration of 5V=120ºC. Check model
number for correct setting.

Verification without calibration
If the Remote Display Module is not available the user may use the follow verification
procedure to ensure the VaporGuard® is still within calibration.
1.
Remove the DDC connector from the Power Supply Module.
2.
Connect the DMM positive lead to connector J5-7 and common to J5-10 of the
Power Supply Module to check the temperature output. Set DMM to DC voltage
mode on 20 volt range.
3.
Place a piece of opaque material (card stock or paper) inside the Source Cup
Assembly. Use template on last page of chapter 5 to create your own level sense
fixture. The photo transistor PCA is closest to the front of the Source Cup
Assembly.
4.
Place the level sense fixture over all phototransistors in the Source Cup
Assembly. Display will indicate 100%. The analog output should read 5VDC.
5.
Slide the fixture so that the next step on the fixture uncovers another
IRLED/Phototransistor pair. Continue until all levels are uncovered.
6.
Check Table 7-1 for corresponding output values for each level.
NOTE:
The software has a discrimination routine that keeps the level stable during
