AC and DC voltage measurement; \u003cbr\u003e\n2. Insulation resistance measurement; \u003cbr\u003e\n3. 100 groups of data storage; \u003cbr\u003e\n4. Automatic calculation of polarization index, absorption ratio; \u003cbr\u003e\n5. Backlight and data retention function; \u003cbr\u003e\n  \u003cbr\u003e\nSpecification: \u003cbr\u003e\nMaterial: ABS plastic. \u003cbr\u003e\nSize: 17.2*14*6.2cm\/6.79*5.52*2.48in. \u003cbr\u003e\nPower supply: 8*AA batteries (not included). \u003cbr\u003e\nMaximum display: 2000 counts. \u003cbr\u003e\nMeasuring range: \u003cbr\u003e\n1. Measure the output voltage: \u003cbr\u003e\nMH12: 50V-1000V, (50V, 100V, 250V, 500V, 1000V,). \u003cbr\u003e\n2. Measure insulation resistance: \u003cbr\u003e\nMH12: 0.1MΩ-10GΩ. \u003cbr\u003e\nAbsorption ratio and polarization index standard. \u003cbr\u003e\nAbsorption ratio DAR: \u003cbr\u003e\nThe ratio of the insulation resistance value at 1 minute to the insulation resistance value at 30 seconds. \u003cbr\u003e\n  \u003cbr\u003e\nPolarization index PI: \u003cbr\u003e\nThe ratio of the insulation resistance value at 10 minutes to the insulation resistance value at 1 minute, to judge whether the equipment has affected the insulation resistance due to moisture. \u003cbr\u003e\nInsulating materials all have the absorption process and polarization process of charge after adding high voltage. \u003cbr\u003e\nThe power system requires that the polarization index should be measured in the insulation test of the main transformer, cable, motor, etc., and this data can be used to judge the quality of the insulation, quality and aging problems. \u003cbr\u003e\n  \u003cbr\u003e\nPackage Included: \u003cbr\u003e\n1 x Resistance megohmmeter. \u003cbr\u003e\n2 x Test lead. \u003cbr\u003e\n2 x Aligator clip. \u003cbr\u003e\n1 x Storage bag. \u003cbr\u003e\n1 x Manual. \u003cbr\u003e\n1 x Packing box. \u003cbr\u003e\n  \u003cbr\u003e\nNote: \u003cbr\u003e\nDue to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures.
