Checking power with a multi-meter
Many DIYRE kits have test pads for testing the power rails with a multi-meter. To confirm that the power rails are correct with a multi-meter, follow these steps:
- Set multi-meter to read DC volts. The symbol for DC is:
- Place the black probe on the test point labeled GND or 0v
- Place the red test point on each of the power test points in turn. These are usually labeled +16v, V+, etc
When testing a power rail, your meter should display the expected voltage within +/-0.5 volts.
