HIPOT Tester 19071/19072/19073 User's Manual
Key [F1] shows "NEW", it means press this key can add a test step. When Function
Key [F1] shows "FIRST", it means press this key can switch the first test step.
(2) Use Function Key [F2] can switch the functions as shown below:
STEP 2/2
VOLT :0.500kV
HIGH :0.500mA
TIME : 3.0s
VOLTAGE IS 0
(3) Function Key [DELETE] to delete a selected test step.
(4) Function Key [INSERT] to insert a new test step set.
(5) Function Key [DOWN] to select to previous test step set.
Selecting Test Mode
■
Press Function Key [F3] to move the highlight and stay in the test item. Use Function
Key [F1] and [F2] to select the test mode. There are AC/GC/PA/OS, AC/DC/GC/PA/OS
and AC/DC/IR/GC/PA/OS test modes for selection by different model. Different test mode
has different test parameters for setting.
Description of each test parameter setting: The following explain the parameter
■
setting of each test mode.
(1) AC HiPot Test Mode
STEP 1/1 AC
VOLT:0.000kV
HIGH:0.500mA
TIME: 3.0s
SELECT MODE
VOLT : Set the required voltage for HiPot test.
HIGH : Set the upper limit for leakage current.
TIME : Set the required time for testing, 0 means continuous test. (Judge the high
and low limit for leakage current during the time.) The voltage value is
shown which within specification, the minimum test time should be ≥ 0.3
second. When the displayed voltage is not reach to 9/10(Software AGC
ON) or 2/3(Software AGC OFF) of setting voltage value, the judgment
function will show FAIL.
LOW : Set the low limit for leakage current, 0 means OFF.
ARC : Set the high limit for ARC, 0 means OFF.
RAMP : Set the required time for rising to selected voltage, 0 means OFF.
FALL : Set the required time for falling from selected voltage to zero, 0 means OFF.
