Introduction to PC9A Digital Micro-Ohmmeter (English)
The PC9A Digital Micro-Ohmmeter is a specialized instrument designed for measuring low resistance values, with applications ranging from metal conductors and wire connections to motor windings and transformer coils. It features an integrated A/D converter and low-drift operational amplifiers, ensuring high measurement accuracy and stable performance. The device covers a wide range from 10μΩ to 1.999kΩ, with six auto-ranging segments (20mΩ to 2kΩ) and corresponding test currents (625mA to 1mA). The large LED display provides clear readings, while automatic range switching simplifies operation. Overload protection is indicated by a flashing "1999" display. Power options include AC 220V or DC 9V (via six R20 batteries), making it suitable for both laboratory and field use. Compact dimensions (240mm×105mm×285mm) and lightweight design (approx. 2.5kg) enhance portability for industrial and research environments.391522
