A simple reality test for a volt meter is to measure a fresh
battery. Zinc/carbon or Alkaline should show about 1.56 volts.
(I learned this test from the bias setting instructions for a
Dynakit Stereo 70 amplifier. They built the amp so the test
point read 1.56 volts when the bias is correctly set and
suggested calibrating your meter with a battery. In that era,
the zinc/carbon battery was what ran almost all of the
flashlights (torches for for English speakers) in the world.
