Megger 210170 Hand Crank Analog Insulation Resistance Tester - Extended Range - 100V to 1000V

Features & Applications:

This Megger 210170 digital insulation resistance tester is the ideal instrument to use when high ranges are needed for measuring insulation resistance. Provides excellent test voltage regulation and an external guard terminal to eliminate surface leakage current from the measurement. It generates a regulated dc high voltage and use low-zero-drift, high-accuracy circuits, with high current sensitivity. Designed for portability, each is enclosed in a molded, impact-resistance, flame-retardant case. This digital, autoranging model provides insulation resistance readings up to 1999 MΩ. It has a 0- to 600-volt ac measuring range. Test voltages of 100, 250, 500 and 1000 volts dc are selected by a rotary switch, and insulation resistance to 1999 MΩ autoranging can be made on the 500 and 1000 V ranges. It incorporates a 3-1/2 digit LCD calibrated directly in megohms, ohms and ac/dc volts. This testers are used to take a series of measurements over a period of time which will show the gradual decline that takes place in the insulation during its operational life. Such monitoring enables the user or to anticipate future performance and to plan ahead for repairs. Also used to show improvements in the insulation of motor, transformer and generator windings that result from drying-out procedures used after exposure to excessive humidity or water.
