MEWOI9042 Online Wireless Clamp on Current Monitoring Recorder
Ⅰ. INTRODUCTION
Click to download: MEWOI9042 User Manual
MEWOI9042 Wireless Online Clamp Current Monitor Recorder use wireless communication to upload test data to concentrator or server for real-time monitoring of current, leakage current, troubleshooting of circuit insulation fault, monitoring of intermittent leakage fault, checking the time of insulation fault and fault location, etc.
|
MAIN FEATURES
| 1. The built-in communication module supports GPRS communication mode (nB-LOT /433/Lora communication mode can be customized), |
2. Adopt the clamp structure and no need to disconnect the tested circuit line, the test is safe and fast. Adopt double layer magnetic shield and digital integration technology, strong anti-interference and high precision.
|
| 3. With the function fo waterproof and dustproof, protection grade IP65. |
| 4. With anti-theft function, equip with built-in electronic lock, control the clamp lock or unlock by infrared remote controller , can be installed in the outdoor and easy for using. |
| 5. With LCDl display screen (display: current value, battery power, monitor number, network signal strength) can be used as a clamp ammeter, which is a multi-purpose machine. |
| 6. Built-in large capacity lithium battery, ultra-long battery life, continuous online testing for 10 days.The monitor is equipped with a charging seat, which can charge 5 monitors once time. |
