No, that's not what HKJ means.
CSV in English speaking countries:
--- Code: ---Time (s), Voltage DC (V)
0.05082, 0.0005
0.111293, 0.0006
0.831361, 0.0006
1.310702, 0.0006
--- End code ---
CSV in European countries:
--- Code: ---Time (s); Voltage DC (V)
0,05082; 0,0005
0,111293; 0,0006
0,831361; 0,0006
1,310702; 0,0006
--- End code ---
That's how Excel works, and it can really mess people up.
IanB:
A few observations from tonight's testing:
1. I would like a way to change the graph update rate (e.g. every second, or every 5 seconds)
- the maximum speed update is sometimes too fast, for example if logging temperature
2. The scroll and pinch gestures on the graph area only affect the time axis, not the vertical axis
- if I pinch or drag in a vertical direction I would like it to affect the vertical graph scale
3. A minor bug: put the meter in temperature mode, press Hold so the value freezes, press Reset to clear the graph
- The vertical axis does not display and graph does not draw a visible line
4. Suggestion: when you press Hold the displayed value is frozen and no new readings are sampled (as expected)
- In this case the graph should stop scrolling since there is no new data to log
5. OS compatibility: I'd like to test the app on my iPad if you can remove the iOS 11.3 required version when installing

Ah right, I've standardized with a ',' symbol. May make it locale aware but no real need at this point.
IanB:
A feature suggestion:
6. When the meter is in auto-hold mode, the logging feature could record one data point per sample (one line of the data table per beep)
This would make it convenient to collect a series of measurements for later processing.

Doh, OK of course.
So in portrait, the save and other buttons are there. But, when I push save it kicks me out of the app (whether logging or not).

Yeah, i get that but axis values Not corresponding - maybe a function of range.?
Also FWIW, i use my iPad mini almost exclusively in landscape mode. Having all buttons available would be nice.

Can you take a screenshot that shows your full portrait screen with one of the DC values that do not correspond, will help in isolating any issue.
I'll try get my hands on an iPad Mini, I haven't got one to test with so in the mean time what are settings that resulted in that error, does it happen every time?

OK, so I can't take a screenshot of the first issue - that is on the iPad mini, when I tap the save button at the bottom of the graph, it just kicks me out of that app every time and puts me back onto the home screen without saving any logged data. This is consistent and does it every single time. The app is still running in the background - I am just booted out of it.
The second issue - the graph axis values with open leads on volt setting was mostly my misreading. I did not immediately get that the small m - meant millivolts and with the tiny font I did not at first see the negative sign for negative values, so without a zero on the y axis it was difficult to orient the labels to what I was seeing on the digital readout. It would help if the axis labels specified the units (eg mV for millivolt - not just m). And with the small font, the negative sign so close to the y axis line with hash marks makes it difficult to discern on the iPad mini.
The x axis time values did not immediately make sense to me either but I think I've now figured them out now.
On the iPad Mini the graphing still has some issues. The axis label font is very small relative to the graph which as I said make the negative sign very difficult to discern. There are also sometimes long pauses before graphing resumes after hitting the reset button. Other times it resumes right away. Lastly the y axis labels with low values (open leads) tend to sometimes, and apparently randomly, throw a microvolt value in with the millivolt values. I have not noticed any of these issues with it running on my iPhone 5s. Screen shots below.
iPad mini 4 - microvolt label inserted amongst millivolt labels on y axis
Also - very small axis label fonts - looks fine here on the enlarged posted picture on a computer screen but on the iPad mini screen the fonts are tiny relative to the graph size - especially the negative - sign.
iPad mini - graph reset but no plotting occurring - even after waiting some time.
iPhone 5s. OK.
