One of the most useful tools in an RV toolkit, used properly, a multimeter helps you fault find electrical problems. Digital multimeters measure voltage, resistance, and more.
A camper has 100's of meters of wire and dozens of appliances and components. When something goes wrong, you need a tool to pinpoint where the problem lies.
The way to use a multimeter differs a little depending on what measurements you’re taking. Here are some hints and tips to get started.
The black probe connects to the COM port; the red to the mAVΩ port.
Choose the function and the appropriate range for the system you're testing.
Be careful not to cross the probes. You may need to apply light pressure to get a good contact.
Check the instruction manual for how your device displays error codes.
