ATEQ does not accept any liability in regard to calibration or settings on its instruments
which are not carried out by its own personnel.
1.8. POSSIBLE PROBLEMS WITH THE AIRTIGHT CELL
If all the other checks do not resolve the problem, check the airtight cell.
Proceed as follows:
9 isolate the instrument from its environment (pneumatic assembly),
9 connect up the instrument (test output ),
9 choose a program which is not in use,
9 set the parameters as follows :
⇒ the regulator to test pressure,
⇒ the pressure monitoring limits to 20 % of the test pressure,
⇒ waiting times A and B 0 seconds,
⇒ fill time 4 seconds,
⇒ stabilisation time 10 seconds,
⇒ test time 10 seconds,
⇒ dump time 1 second,
⇒ reject limit maximum,
⇒ unit Pa/sec,
⇒ function all functions cancelled.
Run two consecutive cycles.
The result after test time should not exceed 2 Pa/sec.
