Power the system down. With continuity, check that VCC and GND are correctly wired to the pins on the microcontroller and other devices. The system may be powering up, but the individual ICs may be wired wrong. Assuming you can get the microcontroller running, set the multimeter aside, and...

Read the multimeter. Wiggle the leads slightly if the outlet is not registering. If it still doesn't register, check the circuit box to make sure the power is on.
straight line next to it). Multimeters are generally not autoranging. You have to set the multimeter to a range that it can measure. For example,2Vmeasures voltagesup to 2 volts, and20Vmeasures voltagesup to 20 volts. So if you've measuring a 12V battery, use the 20V setting. 5V ...
This procedure is also pretty simple. On a battery, you’ll have the multimeter set to read DC voltage (V–). Touch the black lead of the voltage tester or multimeter to the negative terminal, and the red lead to the positive terminal. If you get no reading on your meter, check to ...
off the power of the equipment, remove the casing and you will see a fuse usually located in the Ac input area or power supply section. Measure the fuse with a either an analog or a digital multimeter. If you use an analog meter then select the lowest ohms range which is the x1 ohms...
How to check a fuse with a multimeter If there is 12 Volt at both sides of the fuse, the fuse is OK. If you have a multimeter, there are two ways to check a fuse. The first way is to measure the voltage at both pins (blades) of the fuse. Small fuses in the car have the to...
Use a multimeter or continuity tester to check an appliance fuse. Test a fuse: Touch each end of the fuse with a probe of themultimeterset at RX1 (resistance times 1) or with a continuity tester. The fuse should show continuity, the passage of electricity through the fuse. Replace a fuse...
There are 2 tests we can use to check to see a fuse is good or blown. We can check the fuse visually to see if it's broken or we can do an electrical test on the fuse using a multimeter to see if it's good or blown.
