Frequency Measurement

Frequency measurement is a key feature for working with signals and circuits that oscillate. With this feature, you can measure the number of cycles per second of a signal, or its frequency. To measure frequency:

1. Connect the Leads: Insert the black test lead into the COM terminal and the red test lead into the VΩ terminal (or the frequency input terminal if available).
2. Select the Frequency Function: Turn the rotary dial to the frequency function (often labeled with a 'Hz' symbol). Select the appropriate range if needed.
3. Make the Measurement: Connect the probes to the signal source. The display will show the frequency.

Diode and Continuity Testing

These features are perfect for testing diodes and checking circuit connectivity.

• Diode Test: Allows you to check the functionality of diodes. The DMM sends a small current through the diode and displays the voltage drop. Place the probes across the diode terminals and check the readings. Usually, you'll see a voltage drop (typically between 0.6V and 0.7V for silicon diodes) in one direction and an open circuit (OL or similar) in the other.
• Continuity Test: Used to check if a circuit path is complete. If the circuit is continuous (i.e., there is a path for current to flow), the DMM will beep or display a low resistance value. Just connect the probes to the points you want to check, and listen for the beep!
