Precision Integrating Sound Level Meter Type 2236
User Manual
Auto Start only works if the sound level meter is switched
off at the set time. Then, at this time, the sound level meter
will switch on, reset and, after a pause of 5 seconds, start
measuring with the set-up it had when it was switched off.
Once the sound level meter has started measuring with Auto
Start, you can control it in the normal way. Measurement
will continue until it is switched off manually or the batteries
run out. Logging will continue until the memory is full or the
batteries run out.
If the sound level meter is already switched on at the time
it has been set to automatically start measuring, Auto Start
is cancelled and has no effect.
When the set Auto Start time has passed, Auto Start will be
switched off when you switch off the sound level meter (until
then, it will appear as though it is set in the Auto Start
screen). This prevents the sound level meter from repeating
an automatic measurement every month.
Auto Start does not affect your use of the sound level meter
while the sound level meter is switched on. Therefore, you
can set the sound level meter up to start measuring at a
particular time and date while measuring without affecting
your current measurement results.

Changing the Displayed
Parameter
The parameters available are listed in section 1.2.1. The se-
lected parameter and its level are shown at the bottom of the
screen. After a reset, “––.–” is shown for the level until after
the first second after a Pause. This is because the level is
not yet available. The quasi-analogue scale always shows the
current RMS input signal level, regardless of the selected
parameter.
