This document introduces a new type of photoelectric sensor. The sensor uses a new photoelectric material and structure, which has high sensitivity and resolution. The sensor can be applied to various photoelectric detection fields and has broad application prospects.
This manual describes the purpose of the QHJ series wiring box, which is to equalize sensor sensitivity and output impedance by adjusting output voltage, reducing angular error in multi‑sensor weighing scales.
It provides technical parameters, installation steps, wiring diagrams, and detailed adjustment instructions, including potentiometer tuning and height adjustment, to achieve accurate measurement performance. This manual is written in Chinese.
Verify that the package contains one wiring box and one user manual; contact the company if any part is missing or damaged.
Rotate the potentiometer inside the wiring box clockwise or counter‑clockwise to change the sensor’s output voltage until the measurement error is within the allowed range.
