Pfeiffer Vacuum Leak Detector ASM 102 S

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 directly (if applicable)

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

Automatic Calibration Procedure

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

Check if 'AL' is displayed permanently

Verify if the bargraph is available for leak value reading

Connect a calibrated leak to the inlet port of the detector

Select the gas to be used for calibration

Enter parameters of the calibrated leak

Place the external calibrated leak on the test port

Ensure the new needle has the same diameter as the old needle.

Select the method for needle adjustment

Connect a flowmeter (0/100 sccm) between the helium leak detector (or pump) and the sniffer probe.

Ensure inlet pressure is below 10 mbar.

Cut the new needle to 85 mm / 3.35 inch and insert it correctly into the nozzle.

Adjust until the flowmeter displays the maximum flow value (60 ± 2 sccm).
