I down ON: when I down < Ix < I up ，PASS；
When Ix ≤ I down or Ix ≥ I up，FAIL；（condition I down < I up）
I down OFF: when Ix < I up，PASS；when Ix ≥ I up，FAIL；
The judgement mode of insulation resistance is the same as above.
Current upper limit
of I up
Current upper limit
of I down
Upper Limit of Resistance
Lower Limit of Resistance
PASS/FAIL and LCD, sound alarm
0 s – 999.9s， (Only when withstand voltage is pass)
0.3s – 999.9s (Only in DC withstand voltage and meet the rising time+
test time > waiting time）
0.1s – 999.9s (When in TIMER ON)
Preventing accidental modification of test condition, or forbid the test
condition from being modified.
Current flowing through the insulation resistance and distributed
capacitance between the output lines can be cleared to zero.
When start to test (press START）, output high voltage start signal, and
then wait for while to output high voltage.
Judgment of Current Overrange
Hardware can quickly judge the insulation breakdown. It’s quick and
safety than voltage sampling and reducing the shokc damage to the
product.
Singular signal of sampling current is to judge the potential risk and size
in loop.
Protect people from electric shock and leakage.
File programming and Storage
It can programe 100 test files, each file can have 20 test projects.
