Well, sure. I mean, it's not like the resistence of a diode varies with
voltage.
Oh, wait, actually that's exactly what it does. :-P
So what makes you so certain that passing a current through a sample
can't cause some kind of chemical reaction that affects its electrical
characteristics, given that we don't even know what the hell this
machine is or what it does?

Fortunately, that's pretty easy to work around with a scripting
language. Export tab delimited and then use something like awk to
replcae the tabs with pipes = job done.

Oh, sure, I'm not disputing that. I'm just wondering where the hell some
random user who can barely operate Notepad has heard of pipe-delimited
files from...

Probably a vendor that they interact with who said "we need/will provide
files in this format".
I interact with a company that delivers exams and a company that tracks
exam results and certifications; the typical user of the systems they
provide is non-technical, and they provide data in that type of format -
it's actually fairly widely used because "|" isn't often part of actual
data.
The perhaps surprising thing is that Excel and oocalc both don't have an
option built in for exporting files in that format, given that they are
so widely used.

Nice point ;-)

I got the impression that she created one of these files by mistake, and
then whoever else she was interacting with rewrote the spec to match.
Which still leaves the question "how the hell did you manage to do this
in the first place?" Oh well.

Yeah, I had assumed it would be there...

For a start you know what units it measures and you can research how to
measure “admittance”.
Of course passing a current through a material affects its properties.
Even a resistor will change its resistance as you pass a current through
it and it heats up. The trick is to use as small a current or voltage as
will work and let the material reach its working temperature.
Electronics is not all zeroes and ones, you have to think physical
properties as well.
As for a material having a chemical reaction: If it were to have a
reaction that changed its properties adversely then that is the wrong
way to test it. Someone who understands the problem will come up with a
solution.

There are no stupid questions only stupid answers.
Or as I often say, ask a stupid person, get a stupid answer.

There are no stupid questions. Only stupid people asking questions.

I might argue the *"Only"* if I were that sort of person. ;-)
