Peak-to-peak with peak backup
The peak-to-peak with peak backup measurement principle is selected with the
Measurement mode
setting using the value
“
P-to-P+backup
”
. It is similar to the
peak-to-peak mode, with the exception that it has been enhanced with the peak backup. In
the peak-to-peak with peak backup mode, the function starts with two conditions: the
peak-to-peak value is above the set pickup current or the peak value is above two times the
set
Pickup value
. The peak backup is enabled only when the function is used in the DT
mode in high and instantaneous stages for faster operation.
