Sniffer probe
Leak detector

Global test (A)Localization test (B)The test piece is placed in achamber in which there is a sniffer
probe.
The leak cannot be located.
The tracer gas from the leak accumulates over time inside thechamber. The detector measures
the total leaks.

The sniffer probe is moved over areas likely to contain leaks.
The leak can be located.
The detector does not perform a direct measure of the leak.
The probe captures only a portion of the tracer gas flow escaping from the test piece according to the positioning of the probeby the user. The captured flow depends on:● the distance between the leak and the probe port,● the location of the leak relative to the probe.

Using the sniffer probe
The leak detector is designed to be used only with the manufacturer’s sniffer probe (see chapter “Accessories”).
●
●
●
●
●
●

The sniffer probe should be used for the purposes for which it was designed.
The sniffer probe must not be used in a liquid.
The sniffer probe must not be inserted into an electrical outlet.
The sniffer probe must not be introduced into the human body.
The sniffer probe must not be used without its port.
The sniffer probe nozzle should not be in contact with temperatures < -20 °C and > 60 °C.

Starting a measure

ECO mode enabled: grip the capacitive handle of the sniffer probe.
ECO mode disabled: press the START/STOP button on the control panel.

Stopping a measure

ECO mode enabled: put the sniffer probe down (probe goes into standby
mode after 10 minutes).
ECO mode disabled: press the START/STOP button on the control panel.

Calibration
Calibration helps ensure that the leak detector is correctly adjusted to detect the tracer gas selected anddisplay the correct leak rate.

7.8.1

External calibration
An external calibrated leak is used to calibrate the leak detector.
It is advisable to use a calibrated leak within the range of 10-5 mbar · l/s (10-6 Pa · m3/s), containing theset tracer gas (see chapter “Accessories”). However, the choice of the calibrated leak depends on thelevel of pollution in the work environment.

23/72

Operation
Detector calibration
20 minutes after switching it on, the detector proposes that the user perform a calibration.
For proper use of the detector, this calibration must be performed.
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 detector is working properly,
for intense operation: start calibration at the beginning of each work session (e.g. workin shifts, every 8 hours).

1. Check the following settings (access: menu [Measure]).
● The set tracer gas is that of the external calibrated leak used.
● The name of the calibrated leak reference selected is that of the external calibrated leak used.
● The information of the external calibrated leak used corresponds to the information provided
on the control panel.
● The type of calibration is ‘External’.
2. Place the sniffer probe in the calibrated leak: leak in its dedicated area (1) or held manually (2).

● It is possible to use a calibrated leak other than those proposed by the manufacturer.
● The manufacturer's calibrated leaks are equipped with a hexagonal nozzle to position the leakin the leak detector cover. This nozzle plays no role in calibration.
3. Press the CAL button on the control panel to start calibration.
● A message is displayed on the control panel if the detector tracer gas and the calibrated leakfilling gas are different. Check the 1ststep of the procedure.
4. Following the instructions given by the leak detector. Press [Next] to go to the next step.
At the end of the calibration, the detector returns to ‘Measure’ mode.

7.8.2

Calibration on concentration
A mixture of gases, with known tracer gas concentration, is used to calibrate the leak detector.
The helium in ambient air can be used for a calibration on concentration.
Before launching this function, make sure that the leak detector is in an environment free of tracer gas
pollution.
1. Check the following settings (access: menu [Measure]).
● The tracer gas concentration of the gas mixture used corresponds the data shown on the control panel.
● The type of calibration is ‘Concentration’.
2. Press the CAL button on the control panel to start calibration.
● A message is displayed on the control panel if the detector tracer gas and the calibrated leakfilling gas are different. Check the 1st step of the procedure.
3. Follow the instructions given by the leak detector. Press [Next] to move to the next step.
At the end of the calibration, the detector returns to ‘Measure’ mode.
