Description
DC withstand
voltage test
(DCW)
[W]
Allows you to check whether an electric product or part has sufficient
insulation resistance against the service voltage (dielectric breakdown
does not occur). This test is performed when the dielectric breakdown
cannot be determined because the capacitive components of the test
target are large and a high AC current flows.
Insulation
resistance test
(IR)
[IR]
Allows you to check whether an electric product or part has a sufficient
insulation resistance value against the service voltage.
W-IR/IR-W test
[W-IR]
[IR-W]
Allows you to consecutively perform withstand voltage and insulation
resistance tests.
Withstand voltage test → Insulation resistance test, or
Insulation resistance test → withstand voltage test
Program test
[PROG]
Allows you to consecutively perform withstand voltage and insulation
resistance tests under various conditions.
BDV
measurement
[BDV]
Allows you to measure the start voltage for dielectric breakdown with the
test voltage raised automatically during a withstand voltage test.
