Re: Diode testing with my meter *wierd*

If I set my meter up to test Diodes/transistors I get wierd side
affects.  When I test a diode they should read .2 - .7 from what I
have been reading. Well my meter gives me a measurement of 160 on some
diodes *I have tested a known working one* and 004/0004 *can't
remember which* on a different diode I tested.

Can someone tell me why it is doing this? I read the manual on how to
hook up the leads on the meter, but nothing changed. I really don't
want to spend a fortune on a meter, but I am thinking I might have to
grab one from either radio shack, home depot, or lowes.

IMHO, the key is that you get good conductance (low resistance) in one
direction and poor conductance (much higher resistance), when you
reverse your leads. You can lift one lead to get it out of circuit if
need be.

In circuit measurements generally are worthless unless you've
calculated all parallel paths too. Exception: If you have an identical
(Known Good) board or circuit to reference to, or have measurements
that someone has recorded.
