Operation:
During the test run, wait for one minute, DAR will be
displayed automatically; wait for 10 minutes, PI will be
displayed automatically.
3. AUTO OFF:
System will shut down automatically after 3 minutes
without operation.

7.1.8. Introduction of other Functions:
1. Dielectric absorption ratio (DAR):
Ratio of insulation resistance between 1-min and 30-sec
2. Polarization index (PI):
Ratio of insulation resistance between 10-min and 1-min
DAR :
1-min insulation resistance
30-sec insulation resistance
PI :
10-min insulation resistance
1-min insulation resistance
Lower insulation resistance tested takes a longer test time,
which would deteriorate the object under test. Thus, higher
DAR or PI (as close to 1) would create better insulation
grade of the object under test.
