This manual describes the HB40X series smart current meters, covering power requirements, measurement ranges, display options, and optional relay and transmission functions. It includes detailed specifications such as power supply (AC/DC 85‑260 V, 3 W) and accuracy for DC (±0.8 %+3 d) and AC (±1.0 %+5 d) current measurements.
The document guides users through panel operation, parameter setting (zero, full‑scale, decimal point, digital filter), alarm threshold configuration, and transmission output setup (0‑20 mA or 4‑20 mA). Wiring diagrams and model dimensions are provided for proper installation and application examples. This manual is written in Chinese.
| Power supply | AC/DC 85‑260 V, 3 W |
|---|---|
| DC current measurement accuracy | ±0.8 %+3 d |
| AC current measurement accuracy | ±1.0 %+5 d |
| Relay contact capacity | AC 220 V / 3 A |
| Operating temperature range | 0 °C – 50 °C |
| Relative humidity limit | ≤85 % RH |
| DC current display range | -1999 to 9999 |
| AC current display range | 0 to 9999 |
Enter the parameter setting mode with the appropriate password, then set PvL for the zero value (commonly 0000) and PvH for the full‑scale value; these define the display values for 0 A and the maximum input current.
Use the alarm parameter setting mode (password 0089) to define AH1/AL1 for the upper alarm and AH2/AL2 for the lower alarm; set the relay contact values accordingly to trigger alarms at the desired current levels.
