Be sure to employ the correct electric value for the proper testing to forbid burns or electric shocks.

5. Ports for Banana Head Probes

Near Cen-Tech high tech multimeters come with multiple ports where you tin can plug in the probes. The flexibility of the ports allows you lot to be able to plug in unlike types of Probes. Ofttimes, yous would find two or more ports for the black and red wire.

Oftentimes, yous would find that each port has a design that can conform assistant head probes.

6. Auto-Ranging

With the machine-ranging feature of the Cen-Tech digital multimeter, the multimeter will always selects the correct range for the quantity under test. So your displayed outcome volition always be the most meaning digits of the value you're measuring.

For instance, if your Cen-Tech digital circuit checker is a four-digit multimeter, on measuring an electrical value it would automatically select an appropriate range to display.

So if yous mensurate a voltage rather than the multimeter displaying 0.029V, information technology would rather display 29.34 mV.

How to Use a Cen-Tech Digital Multimeter to Cheque Voltage?

Hither are five steps that brand using the CenTech digital multimeter to check Voltage in Air-conditioning or DC:

Pace 1: Safety

Safe is an essential part of using a multimeter. You need to have into consideration that electricity can be hazardous, and if care is not taken, it can lead to astringent injuries or even expiry.

So, when using a Cen-Tech digital multimeter to check for Voltage, ensure y'all observe the general safety precaution. Furthermore, inspect the multimeter to ensure it is in good working condition such as the probe especially.

Ensure the probes are well insulated so that you would non come in contact with the current straight. Lastly, make sure y'all utilize the right function of the multimeter for the right purpose.

For instance, do non set your multimeter to the DC voltage when you desire to measure AC voltage.

Step 2: Rotate Selector to Air-conditioning or DC Voltage

To ready the function of the multimeter to mensurate an electrical value, utilise the selection knob. In this case, where we would measure Voltage, plow the option knob to either Ac voltage or DC voltage as the case may exist.

Utilize the department that has a V with a direct line to measure DC voltage. Also, use the role that has a V with a wavy line to measure AC. DC voltage is the type of Voltage observed in batteries, while AC voltage is the ane supplied to our abode sockets.

A typical Cen-Tech digital multimeter can measure out Voltages within the range of 200mV to 1000V DC or 2V to 700V Air-conditioning.

Step 3: Plug the probes.

At this stage, plug in the probes to the ports on the Cen-Tech multimeter. At that place are dissimilar ports on the multimeter, sometimes three or four, used for measuring various parameters.

In the example of measuring Voltage, we would exist using only 2 ports, labeled COM (Mutual) and Five/Ω/Hz. Plug the blood-red wire to the port labeled 5/Ω/Hz, and the black wire to the port tagged COM.

Although if yous twist these wires, you will still get the same value, it would exist the negative counterpart.

Step four: Cheque Voltage

Now that you lot have made all the necessary adjustments, all you lot have to do is connect the probes on the live and neutral wire for AC voltage testing.

If yous are testing a DC voltage, connect the black probe to the battery's negative final, and the cherry-red probe to the positive terminal of the cell. Note that zilch terrible will happen when you twist the blackness wire with the red wire.

Your voltage reading will become a negative number of the actual outcome if you lot switch it by mistake. This negativity is considering a multimeter measures the Voltage of a live wire to the Common (COM) port.

Pace 5: Taking your reading

At this stage, your reading will be displayed on the screen. Depending on the model of the Cen-Tech multimeter, you take, merely near frequently, you would become your result in three or four pregnant figures.

If the result on your screen is zilch, at that place is no voltage is in the wire.
