We all recognize the significance of digital multimeters. But, do you know how to use a cen-tech digital multimeter to check voltage adequately?
Knowing how to use a digital multimeter can be pretty challenging if you lack the correct knowledge. However, if you do not know how to use one, do not worry, as you are in the right place.
This article will help you grasp knowledge and prep you for the challenges that you might face while using it.
Cen-Tech produces various multimeters of different ranges and types. However, you do not require knowledge about each device.
With the assistance of this article, anybody will be capable to use any cen-tech digital multimeter easily.
Digital multimeters are great tools for not just electricians but every person today. Each homeowner must possess a multimeter to make sure that the electrical tasks are safe and reliable.
How to Use a Cen-Tech Digital Multimeter to Check Voltage
Various models of Cen-Tech multimeters are available in the market. Also, using it and knowing its functioning is not tricky.
Follow these five steps to measure the voltage of any circuit safely and quickly.
Step 1: Be Safe
One of the most vital parts of using a multimeter is ensuring safety. You need to know that working with electrical circuits or appliances can be dangerous.
Thus, it can lead to fatal shocks and serious injuries if you fail to take proper preventive measures.
So, before using a cen-tech digital multimeter to check voltage, ensure you follow the instructions in the manual as mentioned above.
For instance, check if the multimeter is in excellent working condition. Also, provide probe insulation to prevent direct contact with the current while taking readings.
Moreover, make sure you understand every function and key on your multimeter. It is not guesswork, and one must have the precision to keep themselves and others safe.
Thus, knowing exactly how to measure voltage is vital.
Step 2: Set the knob to DC or AC Voltage
Setting the functions is another crucial part. So, before you begin, turn the knob to Ac or Dc voltage as per the requirement.
Further, pointing to V with a straight line indicates that you are measuring DC voltage and not AC.
Similarly, if it is a V with a curvy or wavy line, the measurements you will be measuring will be in volts. Know your current type and range before using the multimeter to avoid errors and faults.
Just remember, AC is present in the home sockets, whereas DC is usually in batteries.
Step 3: Attach the probes
In this step, you need to plug in the probes in the digital multimeter. Different functions on the multimeter assist in taking various readings like voltage and amp.
To measure voltage, you will need these two terminals, first the COM (common) and V/Ω/Hz. Locate this on your Cen-tech digital multimeter and insert it in the leads correctly.
While plugging in the wire, make sure the red one goes into V/Ω/Hz, and the black one is in the COM.
However, do not worry even if you twist the wires as the outcome will be the same, but the readings might come in negative.
Step 4: Calculate Voltage
After making the essential connections, connect the probes on neutral and live wires to measure any AC voltage reading.
In DC voltage reading, you must attach the black lead to the battery’s negative end. Further, the red jack goes in to the positive terminal.
Like we have read. Nothing terrible will happen if you switch the wires, so do not worry about it.
Only the voltage reading will become negative in this case and not cause any safety issues.
The negative result comes because the multimeter calculates the voltage of the live wire to that of the COM.
Step 5: Noting the Reading
Measuring the readings is simple as well. Digital multimeters use a tone to analyze the measures. Moreover, the digital screen displays all the readings on it, making it easy to note voltage.
Cen-Tech Multimeters have a particular output tone if your process is going well. Moreover, you will quickly be able to detect any error or fault.
If your screen display zero reading, then there is no voltage flow in your circuit.
Taking readings using the Cen-Tech multimeter is smooth. It is a handy tool with no troubleshooting issues or any other notable obstacles.
Moreover, one of the prominent features of this equipment is that its values are precise and accurate. Also, these multimeters are not tricky to use and work well for everyone.

How to Check Continuity with Cen Tech Digital Multimeter
Checking continuity using a cen-tech device may not be as simple as it seems. There are specific rules and precautions that one must take before using a digital multimeter.
So, if you want to check the continuity of a circuit, kindly follow the steps mentioned below.
Step 1: Check Voltage
Before you start with checking continuity, make sure the multimeter reads zero. It is vital to check that the voltage is 0 and not fluctuating.
After this, switch the dial to the Continuity mode, and if needed, press the button.
Step 2: Connect the probes
Attaching wires in place and correctly is a vital step to follow. So, attach the black-colored jack to the COM and the red-colored jack into the VΩmA.
After this, turn the knob to 200 ohms.
Step 3: Switch the dial
If you are getting the reading as 1, you need to shift your dial into a counterclockwise direction. Keep switching it till you do not get a different result.
It is a critical step because reading 1 indicates that your circuit is not closed and open. So, make sure your reading is any other number and not 1 to be safe.
Step 4: Check the connections
After assuring the voltage and connections are in place, attach the test leads to the wirings of the connection.
In this step, you must ensure that your wires are connected correctly to give you the desired results.
Step 5: Take the measures
Noting the measures is not an issue. A digital cen-tech multimeter displays all the actions on its display and is simple to apprehend.
