Test of insulation resistance up to 5TΩ at 250V-5kV (adjustable in 25V /100V steps) for high voltage equipment like transformer, cable, electric motor and more
Supports insulation analysis by polarization index (PI), dielectric absorption ratio (DAR), step voltage measures, temperature compensation, current leakage, log test (up to 8 hours), average value and more
Step voltage test: to check the insulation resistance changes according to testing voltages
Temperature compensation: automatically calculate the insulation resistance under various temperatures
Log test, PI & DAR: to see the leak current decreases after applying a certain voltage
Memories for 100 measures manually and 10 auto-saved records (each 360 measures in maximum) in log test with date & time stamp
GUARD terminal for elimination of surface currents
AC /DC voltage and temperature measurement
Automatic discharge after completed measurement
Built-in calendar, clock and timer. Adjustable measuring time from 30 seconds to 30 minutes
Large and clear LCD with multiple data and bar graph display and back lighting, auto-power off
Alarming: high voltage, wrong input and more
USB 2.0 interface, graphic Windows software and automatic insulation test report
Robust case, rechargeable NiMH batteries & backup batteries for long time working at the spot
Safety as per IEC1010-1 Cat III 1000V & Cat IV 600V
