8 - Operating instructions
Insert the batteries
• Remove the batteries compartment cover at the back of the device.
• Put the 4 alkaline AAA LR03 1.5V batteries supplied with the instrument.
• Carefully respect the polarity.
• Put back the battery compartment.
Perform a measurement
• Place the device in the required location to detect possible gas leak.
• Press ON/OFF key.
• The pre-heating phase of the sensor begins and lasts for 60 seconds. During this
phase, all the visualisation leds of thresholds light one after the other. A few
second before the end of the pre-heating phase, all the leds blinks at the same
time.
• Place the probe as close as possible to the location of the suspected leak.
• Slowly move the probe (approximately 2 cm/second) in the direction to the
possible source of the leak.
It is important to move the probe past the leak and to go back
toward it. The device responds to changes in gas concentration in
the air. Moving the probe allows to the device to respond properly
to these changes.
• If gas is detected, the frequency of the beep repetition will increase
as the detected gas concentration increases and the leds of graphic
visualisation lights from down (low gas concentration) to up (high gas
concentration).
Manual and automatic autozero functioning
The detector performs an automatic autozero every 2 s to set its minimum threshold
of detection. This autozero allows to guarantee an optimum gas detection whatever
the conditions of use (contaminated environment, temperature variations,...). In
case of detection, according to the amplitude of gas measurement, the automatic
autozero will deactivate to guarantee a better location of the leak. It will
automatically reactivate after a return to normal conditions.
In case of high gas concentration with a wide contaminated area, the automatic
autozero can be not enough to detect precisely the location of the leak, there
will be a measurement saturation. In this case, it is possible to perform a manual
autozero into the contaminated area to reset the detection and to get back to a
progressive sensitivity when getting close to the leak source.
To perform a manual autozero, please see next page.
