1. Bluetooth connection: mobile phone can directly control the multimeter. 2. More applications of measurement data: data recording, data graphics, data sharing, data storage and export, threshold alarm. 3. Multi-meter collaboration: APP can connect four Bluetooth multimeters and simultaneously monitor the measurement data of the four multimeters in real time. 4. Intelligent calculation function: use multimeter data to quickly calculate mathematical formulas such as power. 5. Remote assistance: real-time remote screen synchronization, easy zero-distance communication, and ultra-distance real-time monitoring.
