Easily adjust the speaking speed to your liking, allowing you to stay focused on your work without interruptions. Enjoy a seamless and personalized user experience, making your tasks more efficient and distraction-free.
Bluetooth 4.0 stable transmission
Enjoy stable Bluetooth 4.0 transmission, ensuring a seamless connection between the multimeter and your mobile phone or PC. Both devices can display the same screen in real-time, providing convenience and efficiency for monitoring and analyzing measurements on the go.
Bluetooth multimeter and also a data-logger
The Bluetooth multimeter is not just a powerful tool; it's also a flexible data-logger. With its data recording function, you can log measured values and view them in charts or tables. Adjust the recording interval as needed, with a default setting of over 0.5 seconds, providing customizable and precise data capture for your convenience.

Simultaneous measurement of multiple sets of data for analysis and comparison

Enable simultaneous measurement of multiple sets of data for comprehensive analysis and easy comparison. This advanced feature streamlines the process of capturing and evaluating different measurements concurrently, providing users with a convenient and efficient way to assess and compare various data sets in real-time.
Off-line Recording Function
1
After setting the sample interval (1 to 4,200,000 seconds) and the number of recording points (0 to 10,000 points), the multimeter can be disconnected from the mobile phone, the data will be saved in the internal memory of the multimeter.


2
After the recording is finished, to analyze the recorded data, use your mobile app to download the data from the meter's memory. If the battery is low, the meter will shut down for data protection, before the data is downloaded.
Bluetooth Transmission

The measured data can be saved in the mobile phone (CSV format) via the Bluetooth transmission. Users can recall the data in the software at any time for analysis and comparison.

After the data is saved, to quickly share the measurement results, you can share the data in the software, send it to the social media or other software.
