. FEATURES
The meter contains several features that enable you to take
and save sound level measurements under a variety of
conditions.
Features include :
Easy of use.
Easy to read large display.
Six measurement ranges.
Fast and slow time weightings.
A and C frequency weightings.
L, Lmax and Lmin three measured parameters are
monitored during measurement and can be viewed
selectively by pressing the MAX key.
Storage of up to 99 data sets for L, Lmax and Lmin with
elapsed time.
Both AC and DC signal output is available from a single
standard 3.5mm coaxial socket suitable for a frequency
analyzer, level recorder, FFT analyzer, graphic recorder;
etc.
