Frequently Asked Questions - 380562 Extech
How do I measure DC voltage with the Extech 380562?
Set the rotary switch to the DCV position. Insert the black lead into the COM jack and the red lead into the VΩmA jack. Connect the test leads across the circuit or component being measured. Read the voltage on the LCD display.
How do I measure resistance?
Turn the dial to the Ω position. Connect the black lead to COM and the red lead to VΩmA. Touch the test leads to the component leads. Read the resistance value. Ensure the component is disconnected from power.
What does the continuity beep mean?
The continuity function beeps when the resistance between the test leads is approximately 30Ω or less, indicating a continuous electrical path.
How do I replace the battery?
Turn off the multimeter and remove the test leads. Unscrew the battery cover on the back. Replace the 9V battery with a new one, observing polarity. Replace the cover and screws.
How do I test a diode?
Set the rotary switch to the diode symbol (->+). Connect the black lead to COM and the red to VΩmA. Touch the red lead to the anode and black to the cathode. A forward voltage drop (typically 0.5-0.8V for silicon) indicates a good diode. Reverse leads should show 'OL'.
What safety precautions should I follow?
Always start with the highest range and work down. Do not input voltage exceeding the rating. Remove test leads before changing functions. Do not use if the meter appears damaged. Use appropriate personal protective equipment.
How do I measure AC current?
Set the rotary switch to the ACA range (e.g., 200mA or 10A). Connect the black lead to COM and the red lead to the appropriate jack (mA or 10A depending on expected current). Break the circuit and connect the meter in series. Read the current.
What is the maximum voltage the Extech 380562 can measure?
For DC voltage, the maximum is 1000V. For AC voltage, the maximum is 600V. The safety rating is CAT II 600V.
How do I clean the multimeter?
Turn off the meter and remove test leads. Use a damp cloth with mild detergent. Do not use abrasive cleaners or solvents. Ensure no moisture enters the jacks.
How do I use the data hold function?
Press the 'HOLD' button to freeze the current reading on the display. Press again to release and continue measurement. This is useful for capturing readings in hard-to-see locations.
