Digital Multimeter,Infurider YF-90EPC 4000 Counts Auto-ranging Voltmeter Ammeter DMM for AC DC Volt,Amp,Ohm,Cap,Temp,Battery Test with USB Connect to PC

I use the meter every day in my job and found this the best one I have ever purchased I would recommend this to any one

The app doesn't load from playstore and doesn't work. Constantly wants permissions even though they have been granted. So just another cheap multimeter without a working app.

Like that the app that works with it. Nice meter with some nice additional uses when using the app.

This meter looks rugged with the plastic bump casing,tested the various ranges which are in spec, the back light is automatic, which can be annoying.The software is basic but works well on windows 11, though they say up to windows 10.Note if you want to use other leads on this meter they will not reach the contacts because the sockets are recessed, design fault. I have tried cheap and expensive insulated leads from a £500 bench multi meter, And none insulated leads, none of these work.Note in Diode mode it will not rest LED's

I bought this multimeter to do some remote bluetooth data logging of a solar panel battery charge/discharge system. However, the APP data collection does not show negative values!!! Everything is recorded as a positive value even though the meter shows a '-' negative sign.Data is only recorded while there is a bluetooth connection. The link sometimes fails to reconnect and the unit has to be switched off , then on again to reconnect.Supposed to do a 4000 count but the battery went flat after 36 hours without getting anywhere near this number.The other problem is the display is hard to read unless the backlight is on which ONLY comes on in a darkened room! There is no override to turn it on manually.Autoranging is good but there is no way of remotely changing the modes, i.e between voltage and current measurements.Overall disappointing as it wont do what I wanted.

Works as it should, easy to use and easily connects to the app , very happy with it

It was delivered promtly and first impressions are good with a nice clear dissplay. I cannt vouch for it's accuracy as I do not have accsess to any standards but it agrees well with another older meter I have. I contacted the supply with a query and they replied very quickly, brilliant service.

I chose this because, not only does it have a wide measurement capability including temperature but it will also log readings to the phone app and download them to an excel readable file. It was a present for my Son-in-Law who is very satisfied and told me that it performed all these features and integrated with the (Android) app well. Good value for money. 4stars yet as we haven't checked accuracy and reliability.
