Evaluating the display for the function "Tightness test"

Chapter 3.5.2 described "Checking the tightness of the monitored system". This function can be
used to obtain an indication of the tightness of the monitored system.

This is only possible if the switching value "Alarm OFF" has been exceeded. It can be repeated
several times in succession.

This check is advisable

before

carrying out a recurrent function test on a leak detector, to see

directly whether there is any need to look for leaks.

After pressing the button, this is confirmed by a brief audible signal which can be heard once,
followed by a flashing signal, i.e. the Alarm LED flashes briefly to indicate the tightness as fol-
lows:

Number or flashes

Evaluation of the tightness

0

Very tight

1 to 3

Tight

4 to 6

Sufficient tight

7 to 8

Maintenance recommended

9 to 10

Maintenance highly recommended

The smaller the above value, the more tight is the system. The meaningfulness of this value
naturally also depends on temperature fluctuations and should therefore be considered to be an
indicative value.
