Set the voltage boost speed

There are five voltage boosting levels in total

High voltage limit setting

Step "250V" for adjustment, the maximum can be set to 3000V

Scope of conformity setting

have

Set qualified judgment conditions

The set voltage or leakage current can be used as the condition to judge the qualification

Qualification judgment reminder

The buzzer will sound one time for qualified and three times for unqualified

test pattern

Single: one-click test without preset. Continuous: preset voltage can be set, continuous test is fast and quick.

Insulation resistance test function

Dielectric resistance (Mohm), Polarization index (PI), absorption ratio (DAR) test (for ETCR3800B only)

data storage

Test results with date and time, 1000 sets of varistor, 1000 sets of gas discharge tube, 1000 sets of insulation resistance.

Data upload

USB interface, the stored test records can be uploaded to the computer
