TRMS multimeter, motor winding and insulation tester with 30,000 digits. The METRAHIT COIL is a digital multimeter with insulation measurement and short-circuit detection. It is robust and reliable for professional use and has an attractive design with housings made of impact-resistant plastic and is technically state-of-the-art. METRAHIT COIL is a portable and robust measuring device, especially for servicing electrical machines and vehicles, e.g. generators, industrial trucks or forklifts. It is suitable for field use and has an internal mains-independent power supply. TRMS multimeter with 30,000 digits resolution for voltage, current, temperature, etc. Insulation resistance measurement with 50 to 1000 V test voltage and external voltage detection Short-circuit detection with 1,000 V test voltage (surge test). Compact tester for electrical machines, drives and generators. Detection of insulation faults and short circuits between windings, even those that only occur under load, with a test voltage greater than the operating voltage. Extensive multimeter functions for service and diagnosis, e.g. with duty cycle measurement for setting motors running in parallel. The METRAHIT COIL enables simple and efficient diagnosis of short circuits between windings in electrical machines, both in the laboratory and on site. The device is used in particular in the service of machines and vehicles with electric drives. The device is suitable for field use and has an internal mains-independent power supply.
