Dielectric Absorption Ratio - Fluke 1537-II User Manual

Dielectric Absorption Ratio

If appropriate, as part of the insulation test, the Tester stores the dielectric
absorption ratio (DAR) with the measurement. A DAR test has a 1-minute duration
and is measured and stored as invalid data for all insulation tests <1 minute. The
DAR test automatically stops when the insulation test time reaches 1 minute. The
results are available for display after test or by storing the test results and viewing
the DAR field in record. See
The field is identified by:

If appropriate, as part of the insulation test, the Tester stores the
capacitance measurement. The results are available for display after the
test is complete by viewing the capacitance field in the stored record.
