Insulation Diagnosis
1.PI and DAR can be automatically calculated and displayed;
2.Step-voltage measurements and temperature compensation is carried out.
Large Storage Memory
1.Up to 100 manually tested data and 10 groups of log-test data can be saved.
2.Test data can be read on LCD, or uploaded to PC
Clear Display
1.Large-screen display. Test result is displayed with indication through a graduation bar.
2.LCD screen is backlit, which is suitable for viewing when it is dark
PC Communication
1.The meter is equipped with a USB interface, through which the saved test data can be
uploaded to a PC for further table/figure making and report generating with convenience.
