I am preparing to attach meters to my layout to simultaneously watch amperage and voltage. I'm thinking about do I want them in series or in parallel.
If in series, then the voltage does not include the drop across the ammeter. In parallel, the amperage does not include the current through the voltmeter.
Which is better ? Or is the difference too small to even think about ?

Ammeters are in series with the circuit, voltmeters are across the circuit.
You put the ammeter in series with the transformer A terminal to the load (the center rail), and you put the voltmeter across the load…that is from the center rail to the outside rail that you are watching.
Like this...
The Ammeter is said to be, "In series with the load."
The Voltmeter is said to be, "In parallel with the load."
