SRMU single function digital resistance meter is a meter designed for industrial process system. It adopts advanced microprocessor for intelligent control, and the input signal is processed by CPU for clear and intuitive display by high-brightness LED. The size is (48 × 96 mm), the appearance design is beautiful and generous, and the use and maintenance are convenient. It meets ANSI-IEEE, IEC and VDE standards, and has comprehensive protection functions for surge interference and abnormal over-input to ensure the normal operation of this series of products.
The SRMU H1-S1 digital resistance meter is designed for industrial process systems. It converts input signals into readable values using a micro‑processor and displays them on a high‑brightness LED digital tube. The device complies with ANSI‑IEEE, IEC and VDE standards and offers protection against surges and abnormal inputs.
The manual covers measurement ranges, accuracy, environmental limits, power requirements, physical dimensions, wiring diagrams, and safety precautions. Proper installation, shielding, and storage guidelines are provided to ensure reliable performance. This manual is written in Chinese.
