I'll embarrass myself with this one, but so what...

Just got this little hobbyist's pocket analog multimeter, and it has a slot
for 1 AAA battery, currently empty. The manual only mentions it and doesn't
say why is the battery needed. When I connect the probes to test the power,
the needle deflects, correctly indicating voltage/resistance, once again -
without the battery present. So what is the battery for then?



Measuring resistance.
