content: Cool review, interesting cheap meter. Bluetooth and data logging for fifty bucks!Maybe Gossen have competition?https://youtu.be/7BpODKbTyZE

content: Looks like a 121GW knockoff and Dave's meter has not even left the blocks yet.Edit: The title shot with an open Fluke in his hand gives the impression it is the model being reviewed and has proper input protection! Oh well, maybe they will release different (input protection) versions in different countries, like the UNI-T UT61E. The PCB has been designed to accept larger fuses.

content: Mine is sitting in the drawer for the main reason that their app is (was) not in the app store. It required manual install to a link in China. Not going to install any software like that.

content: I did install it, on both an iPad and a cellphone running Android. The logging software is fairly useless, marginally less useless on the Android version. Maybe. Didn't really bother much with it.Typical of Chinese manufacturing to bodge something together vaguely resembling a useful application then abandon it.(They have a newer model out that logs internally as well as having Bluetooth.)

content: Quote from: amirm on May 24, 2017, 05:55:38 amThat seems to have changed. I see "OWON Multimeter BLE" in the Apple App Store, and "OWON Multimeter BLE4.0" in the Google Play store.

content: The OWON B (Bluetooth) series was released 1-2 years ago. The T models have TRUE RMS measurement . The + models have offline recording function (but I think it needs to be activated from the iOS APP, not sure about the Android APP). The 35 series has 3 5/6 digits. There is also a B41T+ with 4 1/2 digit DMM.

content: Quote from: ebastler on May 24, 2017, 09:56:57 amI just tested out the latest version on the iPad -- still shoddy, and truncates the display at the right edge (possibly not tested on iPads despite claiming to work). The Android version works better, but no obvious way to halt logging. No instructions, of course.The meter itself isn't too bad for anything that doesn't require high energy protection, but I think that if you want to log data you'd be better off paying more for something less half-baked.

content: Quote from: IanB on May 24, 2017, 05:07:13 amBad choice of the still title image for that Youtube review, by the way: The opened meter shown there, with the nice HRC fuse, isnotthe OWON but a Fluke that was used for comparison!
