Diris A40/A41 is a device used to measure and measure the electrical parameters of single phase, 2 phase and 3 phase low / high voltage networks. It can set and display all parameters and implement standard functions for multi-parameter measurement, power measurement, harmonic distortion calculation, operating time measurement, wiring error testing, and provide RS485 communication function, multiple harmonic analysis, analog output and monitoring or inspection/control (output/input) function.
The Diris A40/A41 is a multi‑function ammeter for single‑phase, two‑phase and three‑phase low‑ and high‑voltage networks. It measures voltage, current, power, energy, harmonic distortion and operating time, and can be expanded with optional RS485 communication, analog output, pulse output and monitoring modules.
The manual provides detailed physical description, mounting instructions, wiring diagrams, safety specifications, module installation procedures, network configuration for balanced and unbalanced systems, and step‑by‑step instructions for entering setting mode and performing repetitive tests. This manual is written in Chinese.
