How To Read Battery Voltage With Multimeter. That will not help you get accurate measurements. Voltage drop is a reduction of the voltage reading on an electrical component or battery caused by excessive resistance 2 such as an electrical loadFor example if a battery is powering some equipment the voltage is going to drop as energy is being drawn.
The first test with your multimeter will measure DC voltage indicated with a solid line and a dashed line above a letter V. Nevertheless this small battery-operated circuit tester also provides accurate digital readings for current resistance battery tests diode test and. It will also outline what a multimeter is its parts and how to read.
Set the device to read DC direct current voltage.
Turn the vehicles key to the run position and check the multimeter. Make sure your multimeter is not on the auto-range mode. Plug the black probe into COM and the red probe into mAVΩ. Ensure the ignition lights and radio are off.
