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
