Yokins Metal Hand Driven 500V Megger Insulation Tester, 50 Megaohms

Key Features

• Yokins insulation tester (meggers) hand driven generator type Insulation Tester is a compact, portable self-contained Instrument which is used for direct reading of insulation resistance of electrical installations and apparatus. The Insulation tester is composed of a hand driven A.C. generator and a high sensitivity cross-coil Indicator..

• Cross coil indicator: The indicating movement is of the cross coil ratio type and is designed so that voltage fluctuation, caused by irregular cranking have no influence on the results of measurement..

• Infinity adjustment: This has been provided in the Instrument..

• Silent generator: The AC Magnet hand generator drive is extremely smooth and silent. There are no carbon brushes and commutators, to be replaced as in DC generators..

• Quick response: The quick response saves the time and extend the life of the generator..

• General characteristic response time: Less than 3 seconds, when a resistance, the value of which corresponds to the central scale mark is suddenly inserted between measuring terminals..

• Limits of error: The insulation resistance measurement is accurate to within( /-)5% of the indicated value over the effective range and within ( /-)10% of the indicated value at the scale mark for the rest of the ranges in conformity with I.S.2992-1980..

• Tolerance of voltage across measuring terminals: Within ( /-)10% of the rated voltage for scale mark of infinity and more than 90% of the rated voltage for the central scale mark in conformity with I.S.2992-1980..
