2.2.2.3 Carrying the system
The receiver is usually carried in front of the body so that the user
looks diagonally down at the touch screen.
SEWERIN recommends: Use a carrying system for locating op-
erations. The carrying system prevents you from tiring during
work. It also reduces the possibility of radio interference. Ra-
dio interference can occur if the user accidentally covers certain
components in the receiver.
2.2.2.4 Playing back noises
The connected microphone records noises. When a measure-
ment is ongoing, the noises are played back through the head-
phones. You can set the volume of the playback.
The noises are also recorded. Recorded noises can be saved.
Both recorded and saved noises can be played back.
2.2.2.5 Displaying the measurement values
Various measurement values are calculated from the recorded
noises (e.g. current noise level, extreme value of the measure
-
ment).
The measurement values can be displayed in two ways:
●
Visually
●
Numerically
Visual representation
The measurement values are displayed visually on the touch
screen in the main view (volume button):
●
Current noise level (level display)
● Extreme value (black line)
Numerical representation
The measurement value for the noise level is displayed as a nu-
meric value in the centre of the main view on the touch screen.
This measurement value is an extreme value. Whether the ex
-
treme value is a minimum or maximum depends on the settings
