In fact, my goal is a PDA device that does the same thing, them dumps
data down to a PC for further data processing by the user.
Characterizing an HV PS, for example, requires hundreds of readings
on several points, resulting in several thousand readings taken for a
single characterization.
HV is that high voltage? Where I am from high voltage is above 69kv. Anyone
will to work with a PDA near that should get a good life insurance policy.
Get a real meter like the durantz/bmi or my favorite the Reliable Power
Meter now owned by Fluke.
Make damn sure the equipment is rated for the voltage your playing with.
I worked for a EOM that intruduced PDA-IR controls to low voltage circuit
breakers (below 1000v). I agrued against it and fought like hell to stop it.
During the first roll out it was found that IR had little in the relm of
security and false signals were causing unintentioned results,,,,,, "But it
worked fine in the lab. " I will say that the idea of collecting data that
way was ~ appealing to some. I found that most PDA's lack the memory needed
for a real study and every time you move data there is a chance for
corruption.
I know a lot of people love their "electronic assistants". I have not found
one that was not just an extra burden to sync the data base. Call me the
"ancient one"
My data sheets were the shit, and so were my subsequent spreadsheet
plots, not to mention what I could have done, had our firm been able
to afford the expensive math and plotting apps. Had I had a good PDA
and data collection hardware with several ports on it, I could have
gone a long way further in a shorter period during such activities.
I have had execellent luck with Excel. Bit clunky sometimes and ya are
limited in the presentation. I personally love to give my boss the radar
graphs. At least now he finds them funny.
