Radio Shack Micronta 22-204 A Operating Instructions Manual page 2

This high-sensitivity MirRONT A Multi tester is designed to me. a sure AC and DC
voltages, DC current and Resistance with accuracy and ease. The large, single­
knob Range/Function control is easy to use and read. The Range Doubler switch
(V•A/2 - V-n-A) effectively doubles the number of AC and DC scales available.
This means you can obtain meter readings in the upper half of the scale, resulting
in consistent accuracy. An "OFF" position is provided to insure meter protection
during transit.
T he sensitive 15 µA meter movement with 4¼" face and mirrored scale makes
accurate reading a simple matter. The meter scales are in 3 colors for rapid iden­
tification. The lowest DC ranges - 125 m V and 25 µA - are great for solid-
state circuit work. The handle can be flipped around to the back to support the
meter at an easy-to-read angle.
These features combined with rugged design and quality parts insure you of many
years of accurate measurements.
