PI(t2/t1) Polarization index PI is the relationship between insula-
tion resistance values measured after 1 minute PI(t1),
and after 10 minutes PI(t2). Other durations can be
selected if required.
PI (limit) Selected polarization index limit value: appears in the
footer in the measuring menu
DAR(t2/t1) Absorption ratio DAR is the relationship between insu-
lation resistance values measured after 30 seconds
DAR(t1), and after 60 seconds DAR(t2). Other dura-
tions can be selected if required.
DAR (limit) Selected absorption ratio limit value: appears in the
footer in the measuring menu
