6.1. Performing settings
Setting the sensitivity
There are two sensitivity levels: HI (high, default) and LO (low).
The LO level is 8x less sensitive than the HI setting. At high
refrigerant gas concentrations, set the sensitivity to LO.
> Press [ ] briefly to set the sensitivity to LO.
> Press [ ] again to revert to the HI level.
6.2. Finding leaks
NOTICE
Sensor destruction due to desorbing substances (e.g. oils)!
> Do not operate the instrument in contaminated environments.
1. Move the leakage detector to the site where the leak is
suspected.
Leak detection can only be carried out correctly if the probe
is guided directly over the leak.
2. Guide the probe head over the surface to be tested at a
maximum distance of 6 mm and a rate of 2.5 to 5 cm per
second.
- If the instrument detects a leak, the yellow gas concentration
indicator LEDs light up and the instrument starts to beep
rapidly. The larger the leak, the more segments light up.
3. Move instrument away from the leak briefly.
> In the case of high refrigerant concentrations: before going back
to the leak, set the sensitivity to LO.
4. Guide the probe head back to the leak in order to precisely
locate the site.
> Set the sensitivity back to HI as soon as the leak has been
precisely located.
