If the current range sets to [Auto], the instrument will
automatically select the proper current scale.
If the current range sets to [Fixed], it is necessary to set a
value at the upper limit of the current to determine the
current scale, which aims to shorten the test time. It is the
best way for sorting test.

Set leakage current to zero clearing.
Press [Auto Test] key on sidebar to automatically measure
the leakage current of test wire and test fixture and to zero
clearing. At this point, DUT must be removed from the test
line.
Press [OFF] key to clear.

During the judgement of rising, DC withstand voltage test
will judge the value of current test whether is over the
upper limit of striking current alarm.
When the judgement of rising is disabled, DC withstand
voltage test will not judge the value of current test whether
is over the upper limit of striking current alarm.

The setting of the minimum charge current.
It is used to detect the test wire or test fixture whether is
normal connected, to make sure the correctness of the
test result. Since the leakage current is usually quite small
during the DC withstand voltage test, so the lower limit of
leakage current is hard to be the judgement to determine
the test wire or test fixture is correctly connected.
Since DUT is actually with some capacitive, so it can use
charge current of DUT to detect the test wire or test
fixture is normal connected. (The specific steps refer to
the parameter setting of insulation resistance.)
