Long-term measurement
This feature allows you to run a measurement over a long period of time, displaying the
history of the recorded noise level as a graph on the screen.
5.2.1
Procedure
Connect the desired microphone and switch on all participating devices.
In the status bar of the screen, a pictogram indicates which mode of operation is
currently set for the mute button:
Mute button works as a “switch”
Mute button works as a “push button”
For long-
term measurements, it makes sense to use the mute button as a “switch”.
To change it, open the Start menu and tap
Management
>>
Settings
>>
Muting
>>
Switch
>>
.
Then proceed as follows:
Step Description
1
In the HL 7000 Start menu, tap the
Long-term
button.
Result:
The menu for the long-term measurement opens.
Muting is active. In the status bar you will see this symbol
, meaning that
there is still no noise measurement.
2
Set the microphone at the desired measuring point.
3
Use the mute button on the HLE 7000 or the CS-7 to start the measurement.
Result:
Muting is switched off. The recorded sound is played through the
headphones. At the same time, the measured level is continuously displayed
on the screen.
You can pause and resume the current measurement at any time with the mute button.
