🔍 Key Concepts

• How the reference anode selector switch is wired in the diagram • What the two leads of the voltmeter (V) are actually connected to • The difference between protective anodes and reference anodes in an impressed-current cathodic protection system

💭 Think About

• Trace the wiring from the voltmeter symbol back to the hull and to the anode selector: what physical points in the system do its two terminals touch? • Look at whether the voltmeter is tied into the protective anode circuit, the reference anode circuit, or the regulator output, and whether it connects to one anode at a time or more than one at once. • Ask yourself: does any part of this diagram show the voltmeter summing or averaging signals, or is it simply reading between two specific points?

✅ Before You Answer

• Verify which symbol in the illustration represents hull ground and see if one side of the voltmeter is connected there. • Check if the selector switch ahead of the voltmeter connects to a single reference anode at a time or to multiple anodes simultaneously. • Confirm that the voltmeter is not connected in series with the protective anode current path (that would be an ammeter role), but rather in parallel between two points.
