Pfeiffer Vacuum Leak Detector ASM 192 T2

Record internal parameters values displayed during calibration

Did the digital voice announce 'Detector ready for cycle'?

Was there a calibration failure?

Confirm use of uncalibrated leak detector for test cycle

Check if 'AL' is displayed permanently

Verify if bargraph is available for leak value reading

Is the internal calibration function activated?

Is the checking function activated?

Ensure the leak detector is in Stand-by mode.

Enter the signal value delivered by the internal calibrated leak.

Enter the internal calibrated leak parameters set value.

Is the difference between the signal and parameters set value lower than 15%?

If the difference is higher than 15%, perform a complete calibration of the leak detector.

Remove the screw at the end of the sniffer probe using a 2.5 hexagonal key

Insert the new filter into the port

Hold the assembly straight up and screw on the nipple of the sniffer probe, ensuring torque is less than 1 N.m

Install the screw so that it is totally inside the nipple, ensuring a few threads are visible

Needle and Nipple Cleaning (For sniffer probe with rigid nipple only)

Remove the needle using needlenose pliers

Clean the needle delicately with alcohol and a lint-free cloth

Is the leak detector internally calibrated?

Ensure the following are connected properly

Is the selected test mode the one used by the operator?

Select method to set target value

Enter the target value (if applicable)

Connect a calibrated leak to the inlet port of the detector

Select the gas to be used for calibration

Program all parameters of the used calibrated leak

Place the external calibrated leak on the test port
