Source
triggering source (parameter relevant only for alarm pulse function in
digital output mode):
0 – triggering by RMS/Leq level from the first profile
1 – triggering by the Peak level from the first profile
2 – triggering by max level from the first profile
3 – triggering by P-P/Spl level from the first profile mode
5
SourceType
triggering type (parameter relevant only for alarm pulse function in
digital output mode)):
0 – triggering condition checked every second (Current)
1 – triggering condition checked after the end of the
measurement cycle (Periodic)
6
AlarmLevel
triggering threshold value in 0.01 dB format (parameter relevant only
to alarm function in digital output mode)
7
Polarisation/Slope
polarity of external triggering pulse (parameter relevant only to
instantaneous triggering pulse function):
0 – positive polarity
1 – negative polarity
active slope of external triggering pulse (essential for out-of-range
performance):
0 – active positive slope
1 – active negative slope
