Digital multimeters also have a wider range of features than analog multimeters, such as the ability to measure capacitance and temperature.

How to Use a Cen-tech Digital Multimeter

To use a Cen-tech digital multimeter, you will need to:

1. Turn on the multimeter. The multimeter will have a power button or switch. Press or flip the switch to turn on the multimeter.
2. Select the measurement mode. The multimeter will have a dial or button that you can use to select the measurement mode. The most common measurement modes are voltage, current, and resistance.
3. Connect the multimeter to the circuit. To measure voltage or current, you will need to connect the multimeter probes to the circuit. The red probe should be connected to the positive terminal of the circuit, and the black probe should be connected to the negative terminal of the circuit.
4. Read the measurement. Once the multimeter is connected to the circuit, you will be able to read the measurement on the display. The display will show the value of the measurement in volts, amps, or ohms.

Advanced Techniques

In addition to the basic measurements, Cen-tech digital multimeters can also be used to perform more advanced measurements, such as:

• Continuity testing: Continuity testing is used to check for a break in a circuit. To perform a continuity test, set the multimeter to the continuity mode and connect the probes to the circuit. If the multimeter beeps, there is continuity in the circuit. If the multimeter does not beep, there is a break in the circuit.
• Diode testing: Diode testing is used to check the polarity of a diode. To perform a diode test, set the multimeter to the diode mode and connect the probes to the diode. If the multimeter shows a positive reading, the diode is forward biased. If the multimeter shows a negative reading, the diode is reverse biased.
• Capacitance testing: Capacitance testing is used to measure the capacitance of a capacitor. To perform a capacitance test, set the multimeter to the capacitance mode and connect the probes to the capacitor. The multimeter will display the value of the capacitance in farads.
