To measure AC voltage, turn the rotary switch to the V~ position, connect the test leads to the COM and V terminals, and then touch the test leads to the circuit points. Read the measurement displayed on the screen.
Check the battery compartment to ensure the batteries are inserted correctly and have enough charge. Replace the batteries if necessary. Also, check the fuse and replace it if it is blown.
Set the multimeter to the diode test mode, connect the red lead to the anode and the black lead to the cathode of the diode. The display will show the forward voltage drop. A reading around 0.6-0.7V indicates a good diode.
'OL' indicates that the resistance value is over the range selected on the multimeter. Try selecting a higher resistance range or ensure the component is not open-circuited.
Turn off the multimeter and remove the test leads. Open the battery compartment and locate the fuse. Remove the blown fuse and replace it with a new one of the same rating.
Yes, set the rotary switch to the A--- position, connect the red lead to the mA or 10A jack depending on the expected current, and the black lead to the COM jack. Place the meter in series with the circuit to measure the current.
Ensure the multimeter is calibrated, use appropriate test leads, select the correct measurement range, and avoid measuring in high temperature or humidity environments.
Regularly inspect the test leads for wear, replace the batteries as needed, keep the multimeter clean by wiping it with a damp cloth, and store it in a protective case when not in use.
Set the multimeter to the continuity mode, connect the test leads to the circuit or component, and listen for a beep which indicates continuity.
A continuous beep in continuity mode indicates a closed circuit, meaning there is a connection between the two points being tested.
