(3) Test rate
Slow: Test method that uses a stable test value as top priority.
Regular: Test method that finds a balance between stable test value and test speed.
Quick: Test method that saves gear changing time under known test specification conditions.
(4) Spec
Set the test specification of the DC insulation and AC tolerance test; the DC insulation specification
can be set between 0.1MΩ-1000MΩ, 0.1uA-1000uA.
※ When the setting is set as 5MΩ or below 5uA, the maximum test voltage is 650V and the AC tolerance
specification can be set between 0.01mA-5mA.
(5) Offset
AC tolerance test offset.
(6) All-Ground
Ground pin must be set for this mode to perform insulation test for non-grounded cable to specified
grounded cable; its advantage is that the test speed is fast, but its disadvantage is that insulation test is
not performed between non-grounded cables.
All ground test method
(7) Binary
This mode is similar to quick categorization; if there are 8 test pins DUT A B C D E F G H, when test is
performed for each cable or pin, it has to be tested 7 times sequentially in order to determine whether the
DUT passed. But if the quick test method is used, the first time A B C D and E F G H are divided into
two groups for testing, and the second time A B E F and C D G H are divided into two groups for testing,
and the third time A C E G and B D F H are divided into two groups for testing, then the test only needs
to be performed three times to confirm whether the DUT passed. Therefore if the DUT has 128 pins, if
test is performed for every cable or pin, the test has be performed 127 times, but with the quick test
method the test only has to run 8 times. However, the disadvantage is that it cannot find out which are
the error pins and the cable segment resistance will be slightly lower than the actual value because the
cable segments were tested in parallel.
Quick binary test method
(8) Time
Set the DC insulation and AC voltage continuation time for [6] All-Ground and [7] Binary;
the continuation time can be set between 0.01Sec-60Sec.
