Using this pocket multimeter is a breeze. First, insert the two included AA batteries into the battery compartment. To measure different electrical parameters, simply turn the dial to the appropriate setting, like DC or AC voltage, resistance, etc. When you get the reading you want, press the data-hold button to freeze it. Remember, after about 15 minutes of inactivity, the multimeter will turn off automatically to save battery. This is a great feature, but if you need to use it again right away, just turn it back on. The PTC auto - resetting fuse inside protects the current - sensing side. You don't have to worry about replacing it. Keep the multimeter in its hard - shell case when not in use. The case not only protects the meter but also helps you remember to turn it off. And use the cord - wrapping area to keep the leads organized. This will prevent them from unwrapping and potentially causing damage. If the multimeter gets dirty, you can use a soft, dry cloth to clean it. Avoid using any harsh chemicals as they may damage the device.
