Comprehensive test and measurement service provider-Shenzhen Weike Electronic Technology Co.
● High-speed judgment of up to 50ms
● Quick release of residual voltage
● Arbitrary setting of test voltage value (25 to 1000V (1V resolution) setting)
:: Contact check function (to prevent misjudgment due to poor contact)
:: Short-circuit checking function (to prevent substandard products from entering the market)
The main unit cannot be measured separately. Please purchase a separate test cable for the purpose of measurement.
Basic parameters
| Test items | Insulation resistance (DC voltage applied method) |
|---|---|
| Test voltage/measurement range (manual/automatic) |
25 V ≦ V < 100 V (2.000/20.00/200.0 MΩ), 100 V ≦ V < 500 V (2.000/20.00/200.0/2000 MΩ), 500 V≦ V≦ 1000 V (2.000/20.00/200.0/4000/9990 MΩ) |
