offerdle Megger MJ10 Multi-voltage Insulation and Continuity Tester
Item is in unused condition. Meter is new. Box has marks on it from storage. No leads or instruction manual included.Stored in a plant supply room until plant closed.
It has four insulation testing voltages 100 V, 250 V, 500 V and 1000 V with a single measuring range for insulation resistance of 0 to 2000 MΩand∞. In addition it has a 4Ωresistance range making it ideal for use when testing electrical installations to the requirements of BS7671 (1992) (IEE Wiring Regulations).
The tester is intended for the direct measurement of insulation resistance and continuity of domestic and industrial wiring, cables, transformers, motors, generators electrical machinery and appliances. Because it is self-powered, the tester is suitable for use during installation and commissioning work aswell as for service and maintenance applications.
