The DC Low Resistance Tester is a specialized instrument designed for precise measurement of DC resistance in critical components such as transformers, motors, switches, relays, and connectors. Engineered for high performance, this tester achieves a basic accuracy of up to 0.05% and offers exceptionally fast measurement speeds, making it an indispensable tool for quality control and production lines.
At the core of its operation, the instrument applies a high-precision constant current through the device. This advanced approach effectively eliminates lead resistance errors, ensuring that the readings reflect the true resistance value. Coupled with a high-accuracy AD converter, the system provides the stability and resolution necessary for demanding high-precision measurement tasks.
Beyond basic measurements, this DC resistance meter significantly enhances workflow efficiency with its integrated sorting function. Users can freely set the resistance upper limit, lower limit, and nominal value. The unit then automatically categorizes components into “Over High,” “Pass,” or “Over Low” bins, enabling rapid and reliable go/no-go decisions. This combination of robust hardware and intelligent software makes the DC Low Resistance Tester a complete solution for manufacturers and technicians who require reliable, high-speed, and accurate component validation, ultimately improving productivity and ensuring the highest product quality.
