How do i make sure my multimeter is working properly?
Every digital multimeter should display something when you turn it on. The range doesn’t even matter since it will either display zero or something very close for the voltage and current ranges or it’s equivalent of infinity or out of range for the resistance and a few other ranges. Some of the low voltage ranges may pick up noise and they won’t read zero unless you short the leads. Some quick tests you can do: Using the DC voltage range, measure the voltage of a new 1.5V or 9V battery. Be sure to use the proper voltage range if it doesn’t auto-select. You should see around 1.4-1.6 volts or something close to 9 volts depending on which battery you have. If you feel safe doing so, you can check the AC voltage at an outlet. Be sure you select the proper AC range. You should measure anywhere from around 110 to about 130 volts in the US. For resistance, select the lowest range. usually 200 ohms. Short the leads together and it should read around 0.2-0.5 ohms. This is also a quick test to b
