Measurement Function
Keyboard Lock
Preventing accidental modification of test condition, or forbid the test
condition from being modified.
Zero Clearing
Current flowing through the insulation resistance and distributed
capacitance between the output lines can be cleared to zero.
Boot-up Delay
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.
ARC Detection
Singular signal of sampling current is to judge the potential risk and size
in loop.
Ground Current Detection
Protect people from electric shock and leakage.
Volume Adjustment
OFF, low, middle, high
High Voltage Indicator
Window indicator and LED
Storage and Interface
File programming and Storage
It can programe 100 test files, each file can have 20 test projects.
