Re: (ET) one blade not cutting well



You don't want to try it to prove it but these things have survived falls
off ladders.  Once I had to take the movement out to straighten the
pointer from a fall, one of several.  Nothing else busted, still
accurate.  Mine is also pin type.
Got a Triplett mirror scale analog too.  But prefer the 260 - it's
robust.     However it's easier to grab a cheap digital for this Estuff
and I do.  Both these meters will still be around long after they plant
me. 
     Ever see an old telephone bell crank 'ringer' ?  Good continuity
tester just crank the crank and if the line's continuous the bell rings. 
Used it as a demo when teaching school and sometimes as a show display. 
Fascinates people.  Put your fingrs across the terminals gives a pretty
good lectric shock.  Ran across this under the bench couple weeks ago. 
Tested her, Still works.
