shunt will stay the same. We know the current will change. Since the shunt measures voltage drop, we have
to be interested in the voltage or pressure in the system. The resistance value of the shunt is set so that we
know there is a 1 to 1 ratio between amps and millivolts. Therefore, a reading of 2 millivolts on the meter face
is equal to 2 amps of current, 3 equals 3, etc.
From this discussion, it should be clear that any meter capable of reading millivolts can be used with the DC
shunt.
