Set the knob to "20V" in the DC range (the DC Voltage range has a V with a 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 ...

How Do You Check Voltage With a Multimeter? A multimeter is an instrument that can measure voltage, current, resistance and possibly additional parameters. You can also use it to check continuity of cables and check fuses. If you don't know how to use one, read my guide How to Use a ...
A volt-ohm meter (also known as a multimeter) A logic probe (optional) A regulated 5-volt power supply A collection of TTL chips to experiment with Several LEDs (light emitting diodes) to see outputs of the gates Several resistors for the LEDs Some wire (20 to 28 gauge) to hook things...
To test a capacitor, use a multimeter set to the capacitance setting. Disconnect the power, then remove the capacitor. Place the probes on the terminals and check the reading against the capacitor’s specifications. If the capacitor is bad, you need to replace it. Always ensure the replacement...
Power is supplied on one side of the fuse slot and is designed to flow across the fuse to the other side. Use your multimeter to figure out which side is powered and then plug in the add-a-circuit so the red wire is on the other side. This way you can ensure the fuse is being ...
The pinouts that needs to be identified are (in the given order): The coil pins The Common Pole pin The N/C pin The N/O pin The identification of a typical relays pinouts may be done in the following manner: 1) Position the multimeter in the Ohms range, preferably in the 1K range....
Head to the AC breaker and remove the fuse that protects the DC control board. Next, use your multimeter to determine whether the fuse is of good quality or not. While you are at it, you should take a good look at the fuse of the heating element as well. Faulty fuses would cut off...
If the window motor doesn't operate at all, the first thing to check is the fuses. See: how to check fuses. If the fuses are OK, the next step is to check the voltage at the motor and test the motor itself. It's not uncommon for a window motor to go bad. See how to test ...
Check Fuses:Inspect the main fuse and other significant fuses for signs of being blown. Ignition System Test:Using a multimeter, you can check components like ignition coils or distributors for proper function. Repair & Fixing the Issue:
