How to Use Your Multimeter
How to Measure Resistance
Set the rotary switch to the resistance (Ω) setting.
Connect your test leads to the circuit or device you wish to measure. It's crucial to connect the common (COM) test lead before connecting the live lead. When removing the test leads, remove the live lead before removing the common test lead.
Once the leads are connected, the resistance value will appear on the multimeter's display.

How to Test for Continuity
Set the rotary switch to the continuity (s) setting.
Connect your test leads to the circuit or device you wish to test. It's important to connect the common (COM) test lead before connecting the live lead, and to remove the live lead before removing the common test lead when you're done.
If the multimeter beeps, this indicates that there's continuity, meaning the circuit is closed and electricity can flow from one end to the other. If there's no beep, it means there's no continuity, and the circuit is open or broken.

How to Measure AC Voltage
Set the rotary switch to the appropriate AC voltage setting, denoted by V~.
Connect your test leads to the circuit or device you want to measure. Always connect the common (COM) test lead before connecting the live lead and remove the live lead before removing the common test lead when you're done.
Read the AC voltage on the multimeter's display.

How to Measure DC Voltage
Set the rotary switch to the appropriate DC voltage setting, denoted by V-.
Connect your test leads to the circuit or device you want to measure. As before, connect the common (COM) test lead first and remove it last.
Read the DC voltage on the multimeter's display.

How to Measure Capacitance
Set the rotary switch to the capacitance (S) setting.
Connect your test leads to the capacitor you wish to measure. As always, connect the common (COM) test lead before connecting the live lead, and remove the live lead before removing the common test lead when you're done.
The capacitance value will appear on the multimeter's display.

How to Measure Frequency
Set the rotary switch to the frequency (Hz) setting.
Connect your test leads to the circuit or device you wish to measure. It's important to connect the common (COM) test lead before connecting the live lead and remove the live lead before removing the common test lead when you're done.
The frequency value will then appear on the multimeter's display.

How to Test Diodes
Set the rotary switch to the diode test (symbol of a diode) setting.
Connect your test leads to the diode you wish to test. Always connect the common (COM) test lead before connecting the live lead and remove the live lead before removing the common test lead when you're done.
If the diode is in good condition, the multimeter will display a value. If the diode is in bad condition (open or shorted), the multimeter will display OL (overload).
