Standard measurement

Touch the app’s [Hold] button to hold measured values and capture data by touching the [Save Measured Value] button. If connected to an instrument with a hold function, you can use the instrument’s HOLD feature to trigger the app to capture the measured value.

Logging Function

You can specify a logging interval (from 5 sec. to 24 hr.) and then capture data while communicating with the instrument. You can shrink and enlarge graphs of measurement data on the handset. You can also display data for up to eight channels, and you can display statistical data.


The simple oscilloscope function is handy if you think the measured values you’re getting may be anomalous. You can send waveform data such as motor starting current to the app by linking it to the instrument’s INRUSH function.
*CM/DT series only


You can send data automatically to the app simply by placing the probes in contact with measurement points. This capability allows you to save linked measurements without needing to touch your smartphone at all. In addition, the app can automatically generate a PASS/FAIL judgment for the battery based on data captured from the battery tester.
*BT3554-50 series only

Creating reports in the field

You can manipulate measured value data and image data as selected from the data list to create a PDF-format report right there in the field. You can include a title, subtitle, recipient, author, and corporate logo on the report’s cover sheet.

Exchange data in the cloud by connecting to GENNECT Cloud

By logging in to GENNECT Cloud, a cloud service designed specifically for Hioki's GENNECT series, from GENNECT Cross, you can view acquired data in real time from a remote location and share data on the cloud.
