Step 1:  Turn on the Meter

To turn on the Greenlee multimeter, press the power button. The display will light up, and you will see the current measurement. You can also check the battery level on display. If you want to take a measurement, ensure the multimeter is on. If you are not using it, turn the multimeter off to conserve battery life. The multimeter will also turn off automatically after a certain period of inactivity.

Step 2:  Select the Desired Measurement Function

There are many functions available on the Greenlee multimeter. To select the desired measurement function, press the mode button until the desired function is selected. The available functions are DC volts, AC volts, DC, AC current, resistance, and continuity. After selecting the desired function, you can take measurement accordingly. It is important to note that the measurement function must be set correctly for accurate readings.

Step 3: Connect the Probes to the Multimeter

It would help if you connected the probes to the multimeter to take a measurement. For DC voltage measurement, connect the black probe to the COM (common) port and the red probe to the VΩmA port. You can use the same connection for AC voltage measurement. For DC measurement, connect the black probe to the COM port and the red probe to the 10A port. For AC current measurement, connect the black probe to the COM port and the red probe to the mA/µA port.

Step 4: Take a Measurement

After connecting the probes to the multimeter, you can take a measurement. For example, press the range button for DC and AC voltage measurements until the desired range is selected. Then, the black probe is touched to the negative terminal, and the red probe is touched to the positive terminal of the circuit. The display will show the voltage measurement. You can also check the battery level on display. You can take similar measurements for other functions like DC and AC current, resistance, and continuity.

Measuring Resistance:

If you want to measure resistance, press the range button until the “R x 1” is selected. Then, touch the black probe to one end of the resistor and the red probe to the other. The display will show the resistance measurement.

Measuring Current:

To measure current, press the range button until the “A” is selected. Then, the black probe is touched to the negative terminal, and the red probe is touched to the positive terminal of the circuit. The display will show the current measurement.

Testing Continuity:

You can also use the multimeter to test continuity. Press the range button until “Continuity” is selected. Then, touch the black probe to one end of the circuit and the red probe to the other. If there is continuity, the multimeter will beep.

Step 5: Turn Off the Multimeter

After taking the measurement, press the power button to turn off the multimeter. Then, disconnect the probes from the circuit and store the multimeter safely. When not using the multimeter, it is always a good idea to turn it off. This will help preserve battery life.

Taking accurate measurements with a Greenlee multimeter is essential for ensuring the safety of your electrical work. With these simple steps, you can ensure that you’re using your multimeter correctly every time.

What Measurement Can You Take With Greenlee Multimeter?

You can take measurements of AC and DC voltage, AC and DC current, resistance, capacitance, frequency, and continuity with a Greenlee multimeter. Here are the most common things that are measured with a multimeter:

AC Voltage:

The AC voltage setting measures alternating current (AC) in electrical devices. To use the AC voltage setting, connect the black lead to the COM jack and the red lead to the VΩ jack. This will give you a measurement of volts (V).

DC Voltage:

The DC voltage setting on a Greenlee multimeter measures the potential difference between two points in a direct current circuit. To use this setting, first ensure that the rotary switch is set to the “DCV” position. Next, connect the black lead of the multimeter to the point in the circuit with the lower voltage and connect the red lead to the point with the higher voltage. The display will then show the voltage difference between the two points.

Checking Continuity:

The continuity setting on a Greenlee multimeter is used to determine if there is a complete path between two points. To use this setting, first ensure that the rotary switch is set to the “continuity” position. Next, touch the multimeter’s black lead to one point in the circuit and the red lead to the other. If the circuit is complete, the multimeter will beep. If the circuit is open, the multimeter will not beep.

Diode Testing:

The diode testing setting on a Greenlee multimeter is used to test the functionality of diodes. To use this setting, first ensure that the rotary switch is set to the “diode” position. Next, connect the multimeter’s black lead to the diode’s anode and the red lead to the cathode. The multimeter will then display a voltage drop across the diode.

Capacitance Measurement:

The capacitance setting on a Greenlee multimeter measures the amount of electrical charge stored in a capacitor. To measure the capacitance, first set the dial to the capacitance setting. Then, connect the positive lead of the multimeter to the positive terminal of the capacitor and the negative lead of the multimeter to the negative terminal of the capacitor. The reading on the multimeter will be in picofarads (pF).
