Current Measurement: In addition to voltage output, Hipot Testers measure the leakage current that flows through the insulation during the test. The tester provides an indication of the leakage current magnitude, which helps assess the insulation condition of the device or component. Some testers also offer the ability to set a maximum allowable leakage current for pass/fail criteria.
Test current: 1.00-45.00A
Grounding resistance range: 0-600m
Four-terminal test mode to ensure test accuracy
The internal power amplifier circuit drives the current output, which is not affected by the power supply and load
The output holes on the front and rear panels are designed to facilitate the integration of standard chassis
480×272 dots, TFT-LCD display
999.9 seconds test time, which is greater than common 60S test requirements
Keyboard lock function to prevent misoperation
