Calibration

It is advisable to perform a calibration:
● at least once a day,
● to optimize the accuracy of the measure,
● if it is uncertain whether the leak detector is working
properly,
● for intense operation: start calibration at the beginning of
each work session (e.g. work in shifts, every 8 hours).
It is advisable to use a calibrated leak within the range of
10 -5 mbar · l/s (10 -6 Pa · m 3 /s), containing the set tracer gas.
1. Place the sniffer probe in the calibrated leak (calibrated
leak in its storage area or manually handed).
2. Press the CAL button.
3. Follow the instructions given by the leak detector.
Start/Stop a test according to sniffer method by localization
The leak detector is designed to be used only with the
manufacturer's sniffer probe (accessory at the expense of the
user).
1. Install the sniffer probe before turning on the detector.
2. Set the switch/circuit breaker to I.
3. Wait for the detector to enter 'Measure' mode.
4. Test pieces according to graphic opposite.
For the use of another method, see the leak detector
operating instructions.
─ Sweep slowly and from bottom to top, with the sniffer
probe the areas of the piece to be tested that may leak.
─ The test result is displayed on the control panel.
5. Stop the test pressing START/STOP button: screen display
6. Restart a test pressing START/STOP button: screen display
