    1. more than 1 device could be monitored, assuring more measurement safety

    Several units DMMs possibly communicated with the mobile app, freeing people from touching the measured object, human safety fully guaranteed.

    DMM Communications

    1. functioning as multimeter + datalogger

    The measured data always updated, and auto- recorded to the 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 DMMs.

    Multimeter and Datalogger

    1. Offline record function

    A user doesn’t have to leave the phone on measure site, just use App to set the recording interval and sum points. The multimeter will record the data itself and store them in its memory. Load the data from multimeter when there is analysis requirement.
