4.5 I/O
The I/O input/output allows to connect 2.5 mm jacks. It is located at the bottom of the unit behind the
rubber breastplate.
I/O 2
out:
DC continuous analogue output: 0-10V for connection to a recorder or industrial controller.
I/O 1
in
corresponds to the
input
for the launch and stop measurement from an industrial controller and is for
Leq-St – 1/1 oct – NR
measurement modes. Launching of the measurement is made for a continuous high level and stopping the measurement is made for a
continuous low level.
I/O 1 Out
corresponds to the
detection output
compared to a preset sound level and is for
L
-
Leq-St – 1/1 oct
measurement modes.
A high level appears in output when the sound peak pressure level reaches and exceeds a certain value.
For this type of output, the following items must be configured:
•
The level type: choose L, Leq or LPK depending on the mode of measurement.
•
Programming with scrolling knob key the desired level of detection by 1 dB steps.
•
Set a timer for maintaining the continuous signal detection after sub-overshoot sound level (from 1s to 10s by 1s pitch).
4.6 Autonomy
Autonomy provides information on the remaining memory
capacity and allows time measurement
according to the chosen method of
measurement.
The measurement time is calculated automatically based
on the remaining memory capacity. It is immediately
compared to the remaining capacity of the power system:
batteries, battery or AC adapter.
