Quick Start Guide
9.5 Selecting sensitivity levels
Ultrasonic levels can be viewed as a kind of leak "volume."
You can use the "sensitivity adjustment button" to adjust the sensitivity of the METPOINT
to the corresponding surroundings. This will heavily affect the device's acoustic behaviour and
increase or reduce the valid value range. Reducing the sensitivity level will reduce the range of the
leak measurement. However, the "relevant area" illustrated with a circle on the display will also be
smaller, making exact pinpointing much easier.
Sensitivity levels
0 ... 60 dB
10 ... 70 dB
20 ... 80 dB
30 ... 90 dB
40 ... 100 dB
The METPOINT
CID will have its auto function enabled by default and will switch between levels
®
(10 ... 70 dB to 40 ... 100 dB) by itself.
You can set the device's highest sensitivity level (0 ... 60 dB) with the "HiSn" button or manually
select the sensitivity level with the "sensitivity adjustment button." Use this mode if you want to
find small leaks in quiet environments.
9.5.1 Sensitivity adjustment button
The device's maximum sensitivity level (intended for when there are small
leaks and no noise); can be selected with the "HiSn button" or "sensitivity
adjustment button"
Leaks and noise will become "quieter" and the range will decrease.
Leaks and noise will become "quieter" and the range will decrease.
Leaks and noise will become "quieter" and the range will decrease.
Least sensitive level (large leaks, a lot of noise -> for a heavy-duty
application)
You can either use the "Sensitivity" adjustment button
to switch between individual sensitivity levels manually
or select the auto function for adjusting the level. The
sequence is shown in the figure to the left.
