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.
