Insulation tester MI 3201 TeraOhm 5 kV Plus

capacitanceinsulation resistancefor high-voltage

The new insulation tester MI 3201 TeraOhm 5 kV Plus is a portable instrument intended to measure insulation resistance by using high DC test voltages up to 5 kV. MEASURING FUNCTIONS • Insulation resistance measurement • Step voltage insulation resistance testing • Withstanding voltage testing • Diagnostic test (PI, DD, DAR) • R(t) graph plotting • Capacitance measurement • Voltage measurement • Frequency measurement KEY FEATURES • Measuring range up to 10 TΩ • Wide range of DC test voltages: from 250 V up to 5000 V in steps of 25 V • Withstanding voltage: testing of insulation with programmable ramp test voltage from 250 V up to 5 kV and programmable threshold current • Step voltage: insulation resistance measurement with five discrete proportionately set test voltages and programmable timer per step • Automated testing: PI, DD, DAR calculations with automated resistance ranging. All data is displayed during one single measurement • Guard test terminal: for elimination of potential surface leakage currents • Fault finding: fully programmable step voltage and withstanding voltage test functions assist in diagnosing faults in insulation • Graph R(t): real time resistance against time graph plotting facility to graphically illustrate the response of a material to an applied test voltage • Built-in timer: programmable timer from 1 s up to 10+0 min • Automatic discharge of tested object after test • Fast testing: 5 mA current source for quick charging of capacitive load • Accurate: selectable noise rejection filters and shielded test leads included in a standard set ensure accurate measurement • Safe: high CAT IV / 600 V voltage protection
