Function
P0
50/60 Hz filter
P0=1, activated
P0=0, deactivated
P1
Programming the second channel
P1=1, channel 2 is programmed
P1=0, channel 2 is not programmed
P2
Notification of peripheral fault in the event of a measuring
overrange
P2=1, peripheral fault is reported
P2=0, peripheral fault is not reported
P3
P3=1, normal operation
P3=0, both channels in current mode and without wire break
detection
