What must trailer stations have?

For a trailer station, it is essential to have a low range type ammeter. This is because the low range ammeter is specifically designed to measure lower currents, which are typical for trailer lights and brake systems. These systems often operate under lower voltage conditions, and using an appropriate ammeter ensures accurate readings. Proper functioning of trailer lights and brakes is critical for safety, making this equipment vital for any inspection station dedicated to trailers.

Other options, such as a high range type ammeter, advanced diagnostic tools, or a double inspection platform, do not directly address the specific needs for evaluating the electrical systems commonly found in trailers. The low range ammeter’s capability to monitor these lower electrical currents is why it is deemed necessary for trailer stations.
