SUMMARY
To test a 24V DC ammeter rated for 100A, connect it to a suitable load that can draw between 25 to 50 amps. A car battery can be used as a power source, but it must be shorted to a low resistance load, such as several feet of low gauge wire or a motor, for a brief period. This method ensures the ammeter operates within its defined range and accurately measures current flow.
