In my opinion, one hardship is good when it is overcome.
It is easy after any difficulty.
In this matter there are many hardships, if one is not overcome, then - many speculation and confusion could occur.
I am at this stage.....
The measured voltage is presented as xxxH, yyyL, and these values are not stable.
for this problem I read again the EPE project of john becker, in the part of "Data sampling" he says :
"About once a second, the pulse train stops while the 32 sample values are averaged, and the l.c.d. display updated. The
pulse train then recommences for another second. This gives the soil time to respond to the re-application of the a.c. waveform, and for the effects of any d.c. currents to be over-ridden." this is not a problem of designing. he intentionally create this.
this Method similar of IP?(similar). EPE meterial of Data is potential(Volt), we need convert Digital Sample to Voltage. number of side # if 1023 mean voltage in P1and P2 is 5V. if 250 near 1.25v -if 500 2.5v or anything.all these if amplitude is equal=1.
therefor in EPE john we have a voltmeter and current source.for watch current use a mA meter at outut current C1.so R=V/I -ohm
For K (geometric Factor):

Tell me if I'm wrong.
in software Electre pro in section "configuration" -Timing, what is that ? Does this determine the sampling time?
Circuits john and robBrt can be combined.
your RM is Pro. how much did you pay for it ?
how does the switching system work?
i can question ? where are you from?
