6.3.15 Change the sniffer line pressure monitoring
In the operation mode Sniffer (SL200 or SL3000) automatic pressure monitoring is
activated. The preset pressure limits define a maximum and a minimum inlet pressure.
If the pressure does not lie within these limits then generally the caliper is either
blocked or broken. Fault messages are issued according to the following rules:
Inlet pressure > Upper limit: Caliper defective.
Inlet pressure < Lower limit: Gas flow is too low through the caliper (blocked caliper).

"Lower pressure limit SL200 capillary clogged" (lower limit)
"Upper pressure limit SL200 capillary broken" (upper limit)
"Lower pressure limit SL3000 capillary clogged" (lower limit)

6.3.16 Calibrating
In order to be able to measure leak rates correctly, the leak detector has to be
adjusted at regular intervals by calibration. The mass spectrometer is adjusted
automatically.
You can perform the calibration using the device internal calibration leak or using an
external calibration leak. Normally, calibration should take place on a daily basis or if
there is some doubt as to the measurement ability of the device.
