HEAT INSULATION Features: 250 V to 10,000 V with 25 V increments Insulation resistance measurement up to 10TΩ RS232 or USB PC connection Real time resistance against time graph plotting facility User selectable Programmable Timer Automatic discharge of test object after measurement Capacitance Measurement Diagnostic tools High EM (noise) immunity High charging capacity Dual power source Built in internal memory (stores 1000 measurements) CAT IV / 600V Amprobe Industrial High-Voltage Insulation Testers have all necessary features for advanced professional insulation diagnostics. Automated calculation of PI, DD and DAR, combined with a possibility to perform a step voltage test make these instruments suitable for the most demanding customers and applications. Large LCD display allows real time R(t) graphs to be displayed. Windows compatible PC Software and either RS232 or USB communications ports serve for connecting the instrument to the PC and management of the recorded test data.
