multi meter connections

  The unit is a Stereomour, approximately 1 1/2 yrs old. I believe I've found the problem. The power cords ground terminal was broken where it plugs into the wall if this makes any sense. I replaced it with a different cord and the touching phonomina has gone away. I can get the measurement as low as 2.5 and then it goes to 0.0. With the volume knob turned all the way up the speakers (Cornwalls) are silent.

That is good it is solved.  It is not good to have the safety ground open.

^^^^^^^^^^safety ground open?????  You mean my discover?

 

[Grainger49]

Yes!  Good catch.  Good call Paul.

Now if the quickie would get here.

There is also a current (10A max fused-mAuA) input, just put glue in those holes; they will get you in trouble.

That gave me a good chuckle.

  Good thing my fingers won't fit.

    .  .  .    That gave me a good chuckle.

The current input has to be a very low impedance so it will not affect the circuit that it is inserted into.  If you get the meter probe in the current input and go to measure the voltage at an outlet it smokes the current circuit in the meter and most likely much more.

Working in industry I used the current input for tuning 4-20mA loops.  But I can't think of a reason a hobbyist would use it.

I'll plug em' with something in the morning.
