• Guide the sensor slowly (approx. 2 cm/s)
along both sides of the cables.
As soon as the device approaches a leak, the bar
display shows the corresponding refrigerant con-
centration and the signal tone rate or vibration fre-
quency increases in proportion to the refrigerant
concentration.
In dark surroundings, the display lighting and the
two LED lamps switch on automatically.
• To switch the lighting on manually, cover the
sensor below the switch-on button with your
thumb.
Ventilate the sensor thoroughly after each
•
use. To do this, expose the device to fresh air
for approx. 2 minutes before carrying out a
new leak detection.
Measure
Send the device in for repair.
If E2 is still displayed after switching on
again, change the sensor.
