1. More than 1 device could be monitored, assuring more measurement safety
Several units DMMs possibly communicated with mobile app, freeing people from touching the measured object, human safety fully guaranteed.
2. Functioning as multimeter + datalogger
The measured data always updated, and auto- recorded to mobile device, saving labor to do on-site records; the recoding duration, and sampling duration could be customized, accessible in chart mode, facilitating comparison analysis between several B35.
3. Offline record function
User don’t have to leave the phone on measure site, just use App to set the record interval and sum points. Multimeter will record the data itself and store them in its memory. Load the data from multimeter when there is analysis requirement.
