1 Features
* Widely used to test the sound level of the environment, machinery, vehicle, ships
and other noise
* Multi functional: it offers 4 measurement parameters:
Lp (sound level), Lmax (maximum sound level),
Leq (equivalent continuous A sound level) and
Ln (percentage of all readings over alarm value set).
* With alarm set and alarm output
* This instrument permits choice of “A”, “C” or “Flat” Weighting and “Slow” / “Fast”
response times
* DC output: 0 up to 1.3V 10mV / dB
* Auto range selection and digital display with no reading errors
* Manual or automatic shut down. The tester can be switched off by pressing the
power key at any time.
On the other hand, the tester can be set to “Auto-Power-off” between 1 to 9 minutes
