Select the method with the desired multi-gas setting in the method editor. See
"Select method [ } 49]".
3 Press the "Use Method" button.
4 Adjust the flow control valve. When using the multi-gas measurement, use the
thumbscrew to open the flow control valve.
6.4 Calibrating
Use a calibration test to check if the leak detector is correctly set-up and that leak
rates can be correctly measured. This determines the ratio between signal and noise
(signal-to-noise ratio).
For proper leak testing regular calibration is absolutely necessary. You can perform
the calibration only with the calibration leak mounted on the device.
Without calibration, no measurement process can be started. The "Leak Test" button
in the "Mini" and "Measure" measurement windows is not active in this case but is
shown in gray.
To carry out measurements, perform a calibration. Perform the calibration once a day
or if there is any doubt about the measurement readiness of the device. After a
standstill period for the device of more than 12 hours or after regeneration, perform 2
to 3 calibrations in sequence to ensure the required measurement readiness.
► Carry out a calibration which results in the value of the parameter "S/B 100 ratio" >
100.
6.4.1 Perform calibration
► Mini > Calibrate or Measure > Calibrate.
ð The device calibrates. The finished calibration is displayed in the "Measure"
window by the yellow message text "Calibration Finished".
