Leak size display
The digital leak size display is normally off, but if a leak is detected, a
number between 1 and 9 is displayed independently of the sensitivity
setting for all refrigerants containing HFCs and HCFCs.
The number increases or falls depending on the quantity of refrigerant
detected. The maximum value is displayed when the source of the leak
has been found. The following table shows the approximate size of the
leak.
Maximum value displayed Size of leak in g/year
1 - 3 < 2.83
4 - 6 2.83 to 14.17
7 - 9 > 14.17
Battery charge indicator
Change the 4 AA alkali batteries when the red LED lights up on the
operating panel. See the "Maintenance "section on how to insert the
batteries.
Mute switch function
Press the MUTE key to switch the acoustic alarm signal off. Press the
key again to switch the signal on again. (Note: If the MUTE key is pressed
quickly in succession, it takes a few seconds for the sound to be switched
on again.)
Setting sensitivity
Following the warm-up phase, the leak detector is automatically set to
the NORM (normal) sensitivity level and the green LED is on.
Press the SENS key once to change the sensitivity level to HI (high
sensitivity, the red LED lights up), and again for LO (low sensitivity, the
yellow LED lights up).
Test bottle for functional test
The electrical leak detector comes with a test bottle that you can use to
make sure the device is working properly. The test is carried out as follows:
1. Pull the plastic cap off the test bottle (see the illustration below).
2. Switch the leak detector on and wait until it has warmed up.
3. Hold the sensor near the small hole at the top of the test bottle. The
beeping frequency should increase and the digital leak size display
should show a number from 4 to 6, which indicates that the sensor and
the electronics are working properly.
Remove the cap for the test

NOTE:
Don't forget to replace the plastic cap after the test. Replace the
test bottle when the green colour can no longer be seen.
