Multi Gas Leak Detector MGLD.3000
Operating instructions
Probe
• Display indicator of the currently measured concentration (value and unit
ppm) or leak rate (value only).
• Change to dynamic search mode
Entry
• Change (back) to analysis mode
• As the concentration increases the tone sequence of the acoustic signal
of the hand probe becomes shorter. When the threshold value is exceeded,
a continuous tone is emitted. The LED trend indicator also acts
as an indicator for the current concentration relative to the threshold
value.

The dynamic search mode is provided for quick leak detection. The display of
the leakage level is made qualitatively using an indicator with changing color
(green, yellow or red with increasing leakage level).
Using the sliding controller, the sensitivity can be set in 5 levels (min. - lowest
sensitivity to max - highest sensitivity).
The optical and acoustic signal outputs are not based on the absolute concentration
or leak rate, but rather on the quantity of their change. A large
change in concentration generally indicates a large leak.
After detection of a large concentration increase and subsequent removal of
the probe from the leakage, "AUTOZERO" can be displayed between the
sliding controller and the indicator for the leakage level. The sensor returns to
its zero point while this message is visible. During this time the response
characteristics are limited particularly when small leakages are detected.
