Digital multimeters are a type of electrical test equipment that combine a number of measurement functions in one unit. A digital multimeter can be used to measure AC or DC voltage, AC or DC current, resistance, and continuity. Cen-Tech digital multimeters are widely available and relatively inexpensive. This article will explain how to use a Cen-Tech digital multimeter to check voltage.
What You Need
-A digital multimeter
-An AC power adapter
-A small screwdriver
1. Plug the power adapter into an outlet and plug the multimeter into the adapter.
2. Turn the multimeter to the “V” setting.
3. Touch the black probe to the black port on the multimeter and touch the red probe to the red port.
4. Touch the probes to the positive and negative terminals on the adapter.
5. Read the voltage on the display. If it is between 100 and 120 volts, then the adapter is working properly.
How to Check Voltage with a Multimeter
A digital multimeter is a versatile tool that can be used to test electrical circuits for voltage, amperage and resistance. You can use it to check the voltage of batteries, AC and DC power supplies, and electrical outlets. In this guide, we will show you how to check voltage with a multimeter.
To check voltage with a multimeter, you will need to set the multimeter to the “V” or “VOLT” setting. Once you have done this, you can touch the positive lead of the multimeter (red) to the positive terminal of the power supply, and the negative lead of the multimeter (black) to the negative terminal of the power supply. The multimeter will then display the voltage of the circuit.
It is important to note that you should never attempt to check voltage while the circuit is powered on. This can be dangerous and could damage your multimeter. Always make sure that the power is turned off before checking voltage with a multimeter.
How to Check AC Voltage
Using a multimeter to check AC voltage is a relatively simply process. First, make sure that the multimeter is turned off. Next, locate the black lead on the multimeter and insert it into the COM, or common, port. After that, locate the red lead on the multimeter and insert it into the VΩmA port. Once the leads are in place, turn the knob on the multimeter to the AC voltage setting.
After the multimeter is on the AC voltage setting, touch the black lead to one of the hot wires Conduct a test by touching each hot wire to ground with one lead and noting which wire has voltage present. The other wire is called a neutral wire and will not register any voltage on an AC setting.
How to Check DC Voltage
To check DC voltage with a digital multimeter, follow these steps:
1.Set the multimeter to the “DC Voltage” position. This is typically represented by a V with a straight line above it.
2.Connect the black, or common, lead to the COM test terminal.
3.Touch the red lead to the VΩmA test terminal.
4.Place the probes on the points you want to measure. For example, if you want to check the voltage at a battery’s terminals, touch one probe to each terminal.
5.Read the voltage displayed on the multimeter’s screen.
How to Check Continuity
Cen-Tech digital multimeters can be used to check the voltage of a circuit, as well as the continuity of a circuit. Checking the continuity of a circuit is important to ensure that the circuit is functioning properly. To check the continuity of a circuit, follow these steps:
1. Set the multimeter to the continuity setting. This setting is typically represented by an icon that looks like a speaker.
2. Place the probes on either end of the circuit.
3. If the circuit is functioning properly, the multimeter will beep or display a reading of 0 ohms.
How to Check Resistance
With your digital multimeter, you can easily check the resistance of an object. This is useful for checking electrical circuits and components to see if they are functioning properly. To do this, you will need to set your multimeter to the “resistance” or “ohms” setting. Once you have done this, follow these steps:
1. Touch the probes of your multimeter to the two points of the object you want to test.
2. The resistance reading will appear on the screen of your digital multimeter.
In conclusion, using a Cen-Tech digital multimeter to check voltage is a relatively simple process. Before you begin, make sure that the multimeter is turned off and that the probes are securely connected. Once you have done this, you can select the appropriate function and range, and then attach the probes to the correct terminals. Once the multimeter is turned on, you will be able to view the voltage readings on the display.
