Manual, 3/2016, A5E37100388-003
Configuration: Device test: Inputs/outputs: Test of inputs
You can use this function to test the status of the analyzer in-
puts. You can test the following inputs:
•
CAL, pump, SYNC (on the motherboard)
• Binary inputs (on add-on board)
After calling this dialog, apply a voltage of 24 V DC to one of the
three inputs to be tested. The result is displayed in the fourth
line (here: "No active input").
The pin assignments of plug X80 (motherboard) und X50 (add-
on board) are described in section Pin assignments (Page 54).
Result of the CAL, pump, SYNC inputs test
Result of the binary inputs test
The adjacent error message occurs if an attempt is made to call
this function for a device without add-on board.
8.4.3.4 Configuration: Device test: Chopper/IR source
You can use this function to switch the chopper and IR source off for test purposes.
NOTICE
Device failure
Incorrect execution of this function may make the analyzer permanently incapable of
measuring!
Therefore this function must only be carried out by qualified servicing personnel.
Note
The analyzer is not ready for measurements for a certain period if the IR source or chopper
has been switched off. To reestablish the measuring capability, you must therefore provide a
sufficiently long warm-up phase depending on the switch-off period, e.g. by restarting the
analyzer.
