Hioki 3455-01

Measure insulation of high-voltage equipment ( such as transformers, cables, and motors) Adjustable testing voltage ( 250 V DC to 5.00 kV ) in 25 V steps up to 1 kV, and 100 V steps from 1 kV to 5 kV Step voltage testing, temperature compensation, temperature measurement, and leakage current display Automatically calculate and display PI ( Polarization Index) and DAR ( Dielectric Absorption Ratio) Wide measurement insulation range, up to 5 T© ( at 5 kV testing voltage, 1 T© = 1012 © ) Data storage and USB interface Large, Easy to Read Display Maximum 5kV Test Voltage - Up to 5T© of Insulated Resistance Testing The 3455 can generate test voltages ranging from 250 V to 5 kV. Settings can be made in steps as fine as 25 V. Very high insulation resistance measurement up to 5 teraohms is possible. Ideal for All Insulation Diagnostic Applications Functions such as automatic calculation and display of PI ( Polarization Index) and DAR ( Dielectric Absorption Ratio) , as well as step voltage test, temperature compensation, temperature measurement, and leakage current display make the 3455 suitable for a variety of diagnostic applications. Data Memory Function The 3455 provides a manual storage function for 100 data and a logging function for 10 data ( 360 times) . The date and time of measurement are also recorded.
