Support U disk program upgrade
When the customer needs to customize any function and no hardware is involved, the customized changes can be upgraded through the disk interface. You don’t need to send the instrument back to the factory.
Quick import from U disk settings
When multiple HT9920 insulation testers are used in the same production workshop, when new products need to be produced, users need to set the parameters in insulation testers again. It is allowed users to quick import the parameter configuration from U disk to quickly copy the parameter settings between the testers. It improve efficiency while ensuring the consistency of parameter configuration, reducing the possibility of errors.
Low background current
The current sampling part in the traditional instrument cannot be isolated from the ground with high voltage and high insulation impedance. When the DUT or test tool and the ground have poor insulation, the test stability and accuracy are affected by the ground current loop and directly cause the test to fail.
HT9920 insulation tester simulated the high voltage and high insulation impedance isolation between the tester and the ground, eliminating the test problems caused by the ground loop current, so it is particularly suitable for automatic test occasions with complex wiring and tooling.
