[AT] Reading ohms on a digital VOM

Thanks dudley having not used them I was wondering how you take care of the  
fact that differant battery levels give differant readings.

Walt,

The digital Fluke meter I have does not provide any  mechanism for zeroing
out the resistance (ohm) scale.  However, as I  believe someone said in a
post earlier today, for really low resistance  readings (like coils of 1 to 2
ohms) you probably will want to short the  digital meter probes together just
like you would the probes on an analog  meter.  However, instead of then
zeroing out the resistance meter  reading like you would with the analog ohm
meter you merely "remember" this  digital ohm meter reading and then subtract
(algebraically) this "offset  value" from any resistance measurements that
you then make.  Maybe  there are digital meters that do have a mechanism for
zeroing out the  resistance scale.  If so I'd like to have one of them.   It's
asking a lot for me to have to remember this offset value - I often  have
trouble remembering why I even have the meter in my  hands.
