Polarization Index (PI)
As part of the insulation test, the Tester measures and stores polarization index
(PI), when appropriate. A polarization index test requires 10 minutes to
complete. Therefore, the Tester will start a countdown at 10 minutes. When an
insulation test is 10 minutes or more, the polarization test is completed and
stored. The results are available for display during a test by pushing the '
button or by storing the test results and scanning the RESULTS fields. The
field is identified by PI .

Dielectric Absorption Ratio
As part of the insulation test, the Tester measures and stores dielectric
absorption ratio (DAR), when appropriate. A DAR test requires 1 minute to
complete. Therefore, it is measured and stored as invalid data for all insulation
tests less than 1 minute. When an insulation test is 1 minute or more the DAR
test is included in the results. The results are available for display during a test
by pushing the ' button or by storing the test results and scanning the
RESULTS fields. The field is identified by DAR .
