This manual introduces the AWE21 series single‑phase power analyzer, its measurement capabilities, hardware structure and recommended applications. It also details the safety class, input voltage requirements and warranty information.
The document walks the user through unpacking, power connections, configuration of communication interfaces (USB, RS‑232, RS‑485), operation of measurement functions, PC software usage, and routine maintenance such as fuse replacement and cleaning. This manual is written in Chinese.
| Input voltage | 110 V AC or 220 V AC ±15% (47‑63 Hz) |
|---|---|
| Voltage range | 25 V / 75 V / 150 V / 300 V |
| Current range (model A) | 0.02 A / 0.1 A / 0.5 A / 3 A |
| Frequency range | 40 Hz – 1000 Hz |
The analyzer can be powered from 110 V AC or 220 V AC with a tolerance of ±15 % at 47‑63 Hz.
Turn off the power, check the fuse, and replace it with a fuse of the same rating as indicated on the rear panel.
The instrument complies with Safety Class I as defined by IEC 61010‑1.
