Trigger sensitivity
This sets the voltage level of the spectral component of the input signal above 1.5 kHz.
Predefined settings of low-medium-high for the trigger level allow an easy configuration
based on the required trigger sensitivity, where low is the most sensitive setting. You can
configure a custom setting when the session should, for example, store only events >500V.
Mains Signaling. Power distribution systems can carry control signals to remotely switch on
and off appliances (also known as ripple control). The control signals are present only at the
moments that a remote appliance has to be controlled. The Mains Signaling trigger can
capture the occurrence (signal level) of control signals with 2 different frequencies.
Parameters to configure:
Trigger on/off
Mains Signaling Voltage (MSV) frequency 1 and MSV frequency 2 in Hz
Frequency range is 100 Hz up to 3000 Hz
Limit
The voltage threshold limit value is defined as % of nominal voltage. The value is typically in
the range of 1 % to 5 %.
Recording time
The event triggers a 10/12 cycle recording of up to 120 s.
