This high-sensitivity MICRONTA Multitester is designed to measure 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.
Ω
.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.
The sensitive15microamp meter movement with10.8cm face and mirrored scale makes accurate reading a
simple matter.
The meter scales are in 3 colors for rapid identification.
The lowest DC ranges-125 mV and 25 pA — 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.
The "Range Doubler" name is a little misleading. It should really be "Reading doubler, Range halver".
With V. A/2 selected the needle swings twice as far for the smae voltage.
