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.
Capacitance
As part of the insulation test, the Tester measures and stores capacitance when
appropriate. 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 C.
