Shanghai Electric Instrument ZX25a DC Resistor User Manual

The ZX25a DC resistor is a multi‑value resistor composed of six ten‑position switches in series. Each resistance element is connected between switch contacts, and the resistance value is adjusted by moving the brush position. The switches use silver‑plated metal brushes for low contact pressure, long life, and minimal drift. The device can be operated in both horizontal and vertical orientations and complies with the ZBY162‑83 laboratory resistor standard.

The manual describes the intended applications (laboratory, industrial, and educational), provides detailed technical specifications, and lists safety and maintenance guidelines such as pre‑rotation of knobs, power limits, storage conditions, and warranty information. This manual is written in Chinese.
