Is this symbol correctly being used for an ammeter?

Somebody marked up this drawing, and I'm supposed to make the revisions. I'm just questioning if this symbol is correctly being used for an ammeter.

Does it look like a correct symbol was used for the ammeter?

I can provide more context if needed, but this is a 0-50A ammeter, on a CT line from the A phase of a motor to a protection relay.

Right, that's what I would expect.. Any idea what the symbol in the markup is used for?
I would use that symbol to indicate a resistive shunt to be connected to an external (remote) voltmeter to measure the current. Shunts are often used for DC where current transformers do not exist.

It is regularly used for the actual meter 'movements', or coils, on switchgear schematics and wiring drawings.
The 'A in a circle' is a general representation often found on one-line diagrams.
