How to Read a Digital Multimeter

The digital multimeter is a useful tool for testing electronic circuits for integrity, voltage output, resistance and other electronic attributes. Knowing the principles of how a digital multimeter works will enable you to use this valuable testing tool with confidence.

Difficulty: Moderate

Instructions

1. Set the range of the multimeter. The multimeter's readout depends on the scale that is chosen, which is dependent upon the current, voltage or resistance you are measuring.

2. Set the multimeter to register what you wish to measure, according to the specific instructions given for your model of multimeter. Once you have set the multimeter to the proper setting, make your tests according to the instructions. Note the reading.

3. Mark down, or notate, if necessary, the reading you have gotten. Be certain that you've set the multimeter to the correct range, and that the controls were set to measure the parameter you wished to measure.

Tips & Warnings

• Use care when working with high-voltage circuits.
