Line 1
It allows setting the current date/time and the measuring range in the
same way as for the instant value display
Lines 2- 7
These lines show in real time the values of the following quantities
integrated by the instrument: LAeqT, LCeqT, LZeqT, LAFmax, LAFmin,
LAFeqT, LASeqT, LAIeqT, LAE, E, Cpeak+, Cpeak-
Line 8
In this line, the left part shows the duration of the “Ts” measure set in the
programming menu (see § 4.6.2) and the measuring time “Tm”
5. Press the “ ” key to start the integration measurement. The instrument automatically
