How do you check DC voltage with a CEN Tech multimeter?
To measure DC voltage, leave the red lead in the jack marked VΩmA and the black lead in the jack marked COM and turn the dial counterclockwise to the 1000 setting in the DC voltage section (DCV). Take the reading by touching the leads to the exposed circuit wires.
What does DCV mean on a multimeter?
direct current voltage
Understanding Your Multimeter Dial Voltage indicators are labeled as DCV for direct current voltage and ACV for alternating current voltage. You’ll use the former for testing batteries and the latter for testing outlets, fixtures, appliances and electronics.
What setting is continuity on a multimeter?
Know that a reading of 0 indicates perfect continuity. If your multimeter reads 0 ohms, it means that there is perfect continuity in the wire, fuse, battery, or device. Most multimeters will beep continuously when testing a connection with good or perfect continuity.
How do I reset my multimeter?
How to Calibrate a Digital Multimeter
- Set the multimeter to the highest resistance range by turning the dial to the highest “ohm” setting.
- Touch the test probes of your digital multimeter together.
- Press the calibration knob until the display reads “0” on the digital multimeter if you don’t see “0 ohms” initially.
What are the symbols for AC and DC?
Multimeter Symbols You Need to Know
- “V” with a wavy line over it = AC voltage.
- “V” with one dotted and one solid over it = DC voltage.
- “mV” with one wavy line or a pair of lines, one dotted and one solid, over it = AC or DC millivolts.
What is a good ohm reading?
A good set of test leads should normally measure about 00.1 Ohm (that is one tenth of 1 Ohm). With the probes still shorted, waggle the leads about and if the resistance changes significantly, they are faulty.
