Meters
Supported meters
TestNMeasure launches with live Bluetooth support targeted at the OWON OW18B and OW18E. Any other instrument (clamp meter, thermometer, insulation tester, gas detector) works on day one: type its value into the same step and the report marks it as manual. Live support is added one meter at a time, and only after it has been tested on real hardware.
Meters and instruments

|---|---|---|---|
| OWON OW18B | Bluetooth LE | Launch target¹ | Live readout, all functions the meter reports, flags, battery |

¹ Launch target: a meter is listed as supported only after it has been tested on real hardware. The OW18B and OW18E have not been verified on hardware yet, so we do not call them supported until they have.
Request a meter
Which meter do you use? Mail its make and model to support@testnmeasure.app. That is how we choose the next one.
Coming In the app, Request support for this meter sends us its Bluetooth fingerprint (service UUIDs and 30 s of raw packets, with your consent), so we can build a driver without owning the meter.
Your instrument list remembers every meter by name, battery and firmware. One live meter at a time.
