We have now 2017
therefore I thing 87V is missing several features:
- It seems not a robust metter , prtection circuit seems to be outdated, even comparing to 101 -> see Joe tests
- Lacking good connectivity, really attaching separate devices to have BT ... this is almost free those days for other 'free/cheap' metters
- Frequency counter - do I really need a cope to check if quartz is doing well, no really , even some of 10usd metter are doing this better, almost all in now populating microcontroller
- Simple serial monitor - not a rich functionalty , simple serial montor, why I need to have a scope for a basic check ?
- Look at component tester for 10usd , it is doing better for several measurements/tests than 87v, why it is so ...
- 5 counts would be nice addition
- Dual display (sic!) amd better display , some of cheap metters offer are doing this better than 87V
etc. etc. etc.
I think it is time to release a new modern universal metter, good V/I/R/C may be not enaught thse days, see Brymen.
