Digital multimeters use a tone to analyze the measures. Measuring the readings is simple as well. The negative result comes because the multimeter calculates the voltage of the live wire to that of the COM. Only the voltage reading will become negative in this case and not cause any safety issues. Nothing terrible will happen if you switch the wires, so do not worry about it. Further, the red jack goes in to the positive terminal. In DC voltage reading, you must attach the black lead to the battery’s negative end. Step 4: Calculate VoltageĪfter making the essential connections, connect the probes on neutral and live wires to measure any AC voltage reading. However, do not worry even if you twist the wires as the outcome will be the same, but the readings might come in negative. While plugging in the wire, make sure the red one goes into V/Ω/Hz, and the black one is in the COM. Locate this on your Cen-tech digital multimeter and insert it in the leads correctly. To measure voltage, you will need these two terminals, first the COM (common) and V/Ω/Hz. Different functions on the multimeter assist in taking various readings like voltage and amp. In this step, you need to plug in the probes in the digital multimeter. Just remember, AC is present in the home sockets, whereas DC is usually in batteries. Know your current type and range before using the multimeter to avoid errors and faults. Similarly, if it is a V with a curvy or wavy line, the measurements you will be measuring will be in volts. So, before you begin, turn the knob to Ac or Dc voltage as per the requirement.įurther, pointing to V with a straight line indicates that you are measuring DC voltage and not AC. Setting the functions is another crucial part.

Thus, knowing exactly how to measure voltage is vital. It is not guesswork, and one must have the precision to keep themselves and others safe. Moreover, make sure you understand every function and key on your multimeter. Also, provide probe insulation to prevent direct contact with the current while taking readings.

So, before using a cen-tech digital multimeter to check voltage, ensure you follow the instructions in the manual as mentioned above.įor instance, check if the multimeter is in excellent working condition. Thus, it can lead to fatal shocks and serious injuries if you fail to take proper preventive measures. You need to know that working with electrical circuits or appliances can be dangerous. One of the most vital parts of using a multimeter is ensuring safety. Also, using it and knowing its functioning is not tricky.įollow these five steps to measure the voltage of any circuit safely and quickly. Various models of Cen-Tech multimeters are available in the market. Related Posts: How to Use a Cen-Tech Digital Multimeter to Check Voltage
