Any multimeter that is to be used have the ability to measure both DC and AC. It is important to understand the type of current that is going to be measured, as using the wrong setting can lead to a false reading which can be misleading and dangerous. A multimeter will have a dial that allows the user to select between AC and DC, which will be identified using the common symbols seen below. When working with a PV system, voltage is typically measured for the following reasons:

• To check if there is voltage in a circuit before beginning to work.
• To test the performance of a component in a PV system. Is the voltage within an acceptable range given the conditions? The battery should be fully charged, what is its voltage?
