Digital calipers

Subject: Digital calipers

 

My calipers are the dial type and seem to be more accurate than plus or
minus 5 thousandths providing they are properly zeroed first. 

That said, I still make a double check with a micrometer when dealing with
wire or pin sizes, just to be sure. 

Another tool I find useful is a digital micrometer.  Mine is a cheapo Harbor
Freight special that was around $20 on sale a year or so ago.  The digital
readout is not electronic, but mechanical, similar to a car odometer.  I'm
usually wary of cheap tools, but this one has been fool-proof so far.  I
sure makes for easy readability.

It is important to develop a "feel" for your micrometers and calipers when
closing them against your specimen and closing them.  Without this important
control, you will not get consistent, dependable measurements.  BTW, these
instruments must be stored in their closed position to keep them clean and
corrosion free.
