About the design

When you pick up the AMM-1 know that you are holding
a precision piece of equipment. If treated as such it
should provide you with many years of reliable service.
We have chosen a 9V battery as a power source for a
few reasons:

They are readily available

Isolating the AMM-1 from the electrical system under
test, this guarantees that it will only measure what it
is supposed to measure.

Everyone hides these in the back of the book. We are
proud of our specs, so we are put them up front.
