Product Description Ideal for OEM and industrial applications, this 5 kV insulation resistance tester is perfect for the diagnostic testing and maintenance of high-voltage electrical equipment. In addition, this tester features a full suite of test modes, onboard memory, and the ability to stream data/download data to a PC/laptop.Insulation Tester 5kV IRT, IR, IR(t), DAR, PI, DD, SV, Ramp, USB, Battery and Line Powered to 10TOhmsOutput voltage maximum 5kVResistance range max 10TΩSmaller size and lighter weight allows easier transport and use without compromising performance.Timed IR plus PI, DAR, DD, SV and ramp tests maximize diagnostic testing capability.CAT IV 600 V safety rating on all terminals.Date and time-stamped test results reduce the risk of error in result interpretation.Up to six hours continuous testing (5 kV) on a single battery charge.Operate from line power when battery fully discharged (charges while operating).USB Connection to download measurement detailsThe Megger MIT525 5-kV Insulation Resistance Tester is designed for high voltage diagnostic testing and maintenance of electrical equipment. The unit is capable of measuring insulation resistance to 10 TΩ as well as performing various diagnostic tests such as Polarization index, Dielectric Absorption Ratio, Step Voltage, Dielectric discharge, and ramp testing.This new version features a tough dual-case design which provides additional protection for the unit and for users. The MIT525's inner case is fire retardant, providing extra safety when dealing with high voltages. The outer case provides excellent protection against drops and knocks as well as environmental variables. The unit's outer case is actually IP65 rated, meaning it is sealed tightly against dust and water. The unit also features a CATIV 600 V safety rating, good for testing at up to 3000m in altitude. Even with this tough new design, the MIT525 is actually smaller and lighter than its predecessor.Product ParametersResistance Range10 kΩ to 15 TΩ at 5 kVAccuracy (73.4°F [23°C])250 VFrom 1 MΩ to 50 GΩ: ±5%From 1 MΩ to 500 GΩ: ±20%500 VFrom 1 MΩ to 100 GΩ: ±5%From 1 MΩ to 1 TΩ: ±20%1000 VFrom 1 MΩ to 200 GΩ: ±5%From 1 MΩ to 2 TΩ: ±20%2500 VFrom 1 MΩ to 500 GΩ: ±5%From 1 MΩ to 5 TΩ: ±20%5000 VFrom 1 MΩ to 1 TΩ: ±5%From 1 MΩ to 10 TΩ: ±20%AC Voltage (auto-ranging)90 to 264 Vrms, 47 to 63 Hz, 100 VATest Voltage250, 500, 1000, 2500, and 5000 VUser-defined test voltage: 40 V to 1 kV in 10 V steps, 1 to 5 kV in 25 V stepsAccuracy: +4%, -0%, ±10 V nominal test voltage at 1 GΩ load (32 to 86°F [0 to 30°C])CapacitanceRange: 10 nF to 25 μF (with a test voltage set above 500 V)Measurement accuracy: ±10%, ±5 nFCapacitorCharge: <3 s/μF at 3 mA to 5 kVDischarge: <250 ms/μF to discharge from 5 kV to 50 VCurrentRange: 0.01 nA to 6 mAAccuracy: ±5%, ±0.2 nA at all voltages (68°F [20°C])VoltmeterRange: 30 to 660 V AC or DC, 45 to 65 HzAccuracy: ±3%, ±3VShort Circuit/Charge Current3 mA at 5 kVInsulation Test Alarm100 kΩ to 10 GΩGuard Terminal PerformanceGuards out parallel leakage resistance down to 250 kΩ with a maximum additional resistance error of 1% with a 100 MΩ loadDisplay Analog100 kΩ to 10 TΩDigital10 kΩ to 10 TΩInterference3 mA from 450 V to 5 kVTimer RangeUp to 99 minutes 59 seconds, 15-second minimum settingMemory Capacity5.5 hours logging at 5-second intervalsTest ModesIR, IR(t), DAR, PI, SV, DD, Ramp testInterfaceUSB type B (device)Real-Time Output1 Hz output readings (V, I, R)BatteryCharge time: 2.5 hours deep discharge, 2 hours normal dischargeVoltage: 10.8 V, 5.2 Ah Li-ion batteries, meets IEC 62133:2003Life: 6 hours (typical) continuous testing at 5 kV with a 100 MΩ loadEnvironmental ConditionsMaximum altitude: 9842.5' (3000 m)Operating temperature: -4 to 122°F (-20 to 50°C)Storage temperature: -13 to 149°F (-25 to 65°C)Humidity: 90% RH non-condensing at 104°F (40°C)IP rating: IP65 (lid closed), IP40 (lid open)Safety: CAT IV 600 V to 9842.5' (3000 m) altitudeDimensions12.4 x 11.2 x 7.1" (315 x 285 x 181 mm)Weight10 lbs (4.5 kg) Packaging & Shipping
