Description

Kikusui TOS7301 High-Speed Insulation Resistance & Battery Insulation Resistance Tester with dV Judgement, 25 Vdc to 1000 Vdc, 10 GΩ

The Kikusui TOS7301 is the high-speed, advanced-function model in the TOS7300 series, designed for insulation resistance testing where takt time and visibility of changing measurements matter. It supplies 25 Vdc to 1000 Vdc in 1 V steps and measures from 0.001 MΩ to 10.00 GΩ, with a selectable aperture time as fast as 10 ms. Its dV judgement function can stop a test when repeated voltage changes exceed the configured delta, helping protect the equipment under test, while the 4.3-inch colour LCD can graph measured data to make abnormal characteristics easier to identify. USB, RS-232C and SIGNAL I/O are standard; this model does not include LAN.
