It is not a strange question. The sensitivity of digital ohmmeters vary
quite a bit. When you are testing 100 lames just prior to a competition,
you need to look at how efficiently you are going to be able to sample the
entire surface to reject those with dead spots. The armorer strokes across
the lame using the conductive terminal attached to the weight. Analog
ohmmeters would "flicker" over a dead spot quicker than MOST digital
ohmmeters. The more expensive digital ohmmeters have a higher sampling
rate (1000 Hz vs 10 Hz), that is, number of observations per interval of
time. Theoretically (Nyquist frequency), one has to sample at least twice
as high as the frequency that one aims to reproduce digitally. An expensive
Fluka ohmmeters would be equivalent for the task (i.e.: stroking along
across from side to side in the anterior surface of the lame in a time less
than a second). Using a digital ohmmeter that is sampling at 10 Hz, you
only will detect death spots of 2 or 3 inches, while using one that samples
at 1000 Hz will have a much higher sensitivity. I think that digital
ohmmeters over $100 (professional grade) will be OK, but those $19.99 from
Radio Shack would not make it for this task at this speed.
Hope that it helps. Thanks again for the lock-tite tip (Thread lock), I
used the red level.
