Product Description
The Digital Micro-Ohm Meter DM-201 is a high-accuracy, 10A low-resistance testing instrument designed for applications requiring extremely precise micro-ohm measurements. With 7-decimal resolution and a 4.5-digit LED display, it provides clear, stable, and highly reliable readings across a wide resistance range from 0.1 µΩ to 19.999 kΩ.
Engineered for demanding industrial applications, the DM-201 delivers 10A test current at the lowest ranges, ensuring accurate measurement of very low resistance values such as circuit breaker contacts, switch contacts, busbars, and heavy-duty conductors. For higher resistance ranges, the instrument automatically reduces current to maintain accuracy.
Its 4-terminal Kelvin connection eliminates errors caused by lead and contact resistance. The SET ZERO knob helps achieve quick zero adjustments and drift-free operation, making it ideal for laboratory and production environments.
The DM-201 is widely used for testing copper and aluminium wires from 0.1 mm to 15–16 mm diameter. It is also suitable for transformer winding resistance measurement, including both primary and secondary sides of potential transformers.
