How use DT830b digital multimeter?

On the DT830b multimeter, place the red probe in the V, W, mA port of the power supply and put the black probe in the COM port. To read the voltage of the DC power supply, you can turn on the digital multimeter and select the appropriate reading mode. You can select either 200m, 2000m, 20, 200 or 1000V.

How do I turn on my multimeter?

To begin, make sure no current is running through the circuit or component you want to test. Switch it off, unplug it from the wall, and remove any batteries. Plug the black probe into the COM port on your multimeter. Plug the red probe into the VΩmA port.

What are the advantages of digital multimeter?

Advantages of digital multimeter:

• The output can be interfaced with external equipment.
• They are having high input impedance, so there is no loading effect in multimeter.
• They are available in smaller sizes or compact.
• An unambiguous reading is obtained.
• There are more accurate than an analog multimeter.

How to use dt830b digital multimeter to read voltage?

Firstly, let’s see how to use the DT830B digital multimeter to read the voltage of any electronics. In this example, I’m using a 12V DC power supply with a DC connector to plug the computer fan. On the DT830b multimeter, place the red probe in the V, W, mA port of the power supply and put the black probe in the COM port.

Where do you put the probe on a digital multimeter?

Put the black probe of the multimeter on the negative end (-) of the connector and the red probe to the positive side (+). You can measure directly the voltage using the digital multimeter since you don’t have to disconnect the fan while you do the readings.

How to use a multimeter-the Home Depot?

Step 1: Plug your multimeter probes into the jacks labeled common and DC voltage. Use the black plug for common and the… Step 2: Adjust your multimeter to measure DC voltage. Some models have a knob, while others use a push button. Adjust… Step 3: Touch the probe connected to the DC voltage

What is the accuracy of the m-830b digital multimeter?

(This means that you can measure changes of voltage of one two thousandth of the maximum, but the actual accuracy of the measurement is only one hundredth of the maximum.) The 830B is made by several manufacturers and sold under many brand names.
