Model: MS5202 - Measure insulation resistance in the current-carrying elements of high-voltage power networks - The measurement results are shown by means of a big pointer indicator with a mirror scale meant for increasing of measurement accuracy. The digital display shows output voltage. Since the insulation resistance testing requires high voltage (up to 25 kV) the Mastech MS5202 uses a double confirmation system for test setup and control over operation - Designed according to the IEC1010-1 standard CAT II 5000V - Analogue and digital display - Inner battery test function is provided - Double test switch is to avoid incorrect operation - Unique design is to protect inner circuit from wet and cankerous air - The instrument tests insulation up to 100000 Mohm at 2500 V - Insulation resistance accuracy (analog display): 100 ~ 50000 Mohm+/-2.5% 0 ~ 100 Mohm/50000 ~ 100000 Mohm +/-3.0% - Automatic range control - Output voltage (digital display): 2500 V+/-5.0% (100 ~ 50000 Mohm) - The tester is powered from 8 x AA 1 5 V batteries (included) and 1 x 6F22 9 V battery (included) - Package includes: - 1 x MS5202 insulation tester - 2 x Alligator clips - 8 x AA batteries - 1 x 6F22 battery - 1 x Carrying bag - 1 x English/Chinese instruction
