HIOKI 3159 Insulation/Withstanding HiTester
Perform insulation resistance and withstand voltage testing in a single series
Continuous testing of insulation (500/1000 V) and withstand voltage (500 VA transformer capacity). Insulation to withstand series test or witstand to insulation series test at auto mode, or individual test at manual mode. Save up to 10 test settings each for the withstanding and insulation testing modes. Externa I/O, RS-232C interface, Status output (relay contacts).
