Sharing a Shunt [RE-wrenches]

	Oh, those darn E-meters. The sharing of the shunt was mainly directed at
analog meter movements. The shunt input of the E-meter is a electronic
differential input of a sensitive operational amplifer. Anything that
interferes with the common-mode of that op-amp, or induces offset voltages
will interfere with the reading, as will some types of AC hash on the DC
power cables. Sometimes it works, and sometimes you have to keep trying.
