Dave makes a good point. Unless the ammeter got slammed with high current and the needle support pegged & needle or shaft was somehow bent there isn't much that needs calibration. If the generator is putting out volts but very low current that might keep the battery up with just the engine load. Once you start using the high current draw items simultaneously is where you would see the no charge condition.

You can check for volts as was mentioned but I don't think an ordinary VOM will have the capacity to see what the generator is putting out in current. If you can get ahold of a clamp on meter that can read DC then that would work. If not you might have to take it somewhere that has charging system test equipt.
