signed to provide maximum insurance
against damage to the component parts.
Very accurate carbofilm resistors are
used to assure long life and depend-
ability. The rectifier for A.C. voltage
measurements is of the full wave bridge
type to provide vibration-free operation
of the meter at all frequencies. The
batteries will have a long life under
normal use, because their maximum
current is held to a small amount.
100 MICROAMPERES-BASIC SENSITIVITY
The indicating meter has a sensitivity
of 78 microamperes. This is shunted
for all measurements so the meter
circuit has a basic sensitivity of 100
microamperes. For the first time in
any commercial multi-tester, the
sensitivity for А. C. voltage measure-
ments is 10,000 ohms-per-volt! This
means that the Simpson Midgetester
