Gossen Metrawatt Z270M Coil Adapter XTRA for Winding Short-Circuit Testing with METRAHIT IM Series

When testing motors, transformers, or chokes for inter-turn faults, the Gossen Metrawatt Z270M Coil Adapter XTRA connects directly to your METRAHIT IM series multimeter. It uses the impulse voltage method to detect shorted turns and winding insulation defects that ordinary resistance measurements miss.

Why choose it

The Z270M extends the capability of your METRAHIT IM multimeter to perform reliable winding short-circuit tests. It provides the necessary interface and accessories to apply the impulse voltage method, enabling early detection of insulation weaknesses before they lead to costly failures.

Ideal use cases

• Quality control in motor and transformer manufacturing
• Maintenance and troubleshooting of industrial electrical equipment
• Testing coils and relays in automotive or appliance repair
• Field service for generators and large motors

Good to know

The maximum test voltage depends on the connected METRAHIT IM instrument, up to 1000 V. The adapter is designed for use in environments with up to 75% relative humidity and temperatures from -10 °C to +50 °C during operation.
