7. Check the calibration of the IE convertor
After the temperature sensor calibration, the residual currents of the IE
convertor circuitry of both sensor boards should be checked.
•
Switch cel off and disconnect cell cable.
•
Set the oven temperature at Toven = 35
o
C. Allow the detector to
stabilize for 30 minutes.
•
Go to the SERVICE mode by holding the <ENTER> button for 4
seconds in the MAIN screen. Enter the Adjustments screen (F4) and
subsequently go to ZER.IE adjustment screen (F2) of sensor board 1.
•
Follow the instructions in chapter 5 on page 24 of the service manual.
Only re-adjust the I/E convertor using the AUTO function if the residual
currents for the different resistors is higher than the values specified in
table VIII of the service manual.
•
After the IE convertor calibration, leave the service mode and enter
the DC mode. Make sure that no cell cable is connected and scroll
through all current ranges. Check if the cell current approaches 0 in all
ranges which gives an indication that the calibration procedure was
completed successfully.
•
Follow the same procedure for sensor board 2. One can access board
2 in the SERVICE mode by selecting board 2 with the “+” / “-“buttons
in the SERVICE mode main screen.
8. Dummy cell test
Perform a dummy cell test for both sensor boards as described in chapter 15
on page 55 of the DECADE II user manual (171.0010).
After completion of this installation & calibration procedure the DECADE II with
dual sensor board is ready for use !
