Frequently Asked Questions - 31-6113 Clas Ohlson
How do I measure DC voltage?
Set the dial to the V (DC) position, connect the test leads to the device, and read the display. Make sure the red lead is in the VΩmA terminal and the black lead in COM. For unknown values, start with the highest range and work down.
What do the symbols on the dial mean?
The dial positions represent functions: V for voltage (DC or AC), A for current, Ω for resistance, and the sound wave icon for continuity. A battery icon indicates the battery is low.
How do I perform a continuity test?
Turn the dial to the continuity symbol, connect the leads across the circuit. If resistance is below approximately 100 Ω, the buzzer sounds continuously.
How do I replace the battery?
Remove the screw from the back cover, lift the cover, and disconnect the old battery from the snap connector. Attach a new 9 V battery, close the case, and tighten the screw.
What is the maximum voltage I can measure?
The maximum DC voltage is 1000 V, and the maximum AC voltage is 750 V. Do not exceed these limits to avoid damage or injury.
How do I measure resistance?
Ensure the circuit is de-energized, then set the dial to Ω mode, connect the test leads across the resistor, and read the value. For in-circuit measurements, isolate the component.
Why does the display show '1' or 'OL'?
This indicates an overload or an open circuit. It means the value is above the selected range or no connection is made. Select a higher range or check the leads.
Does the multimeter have an auto-off function?
Yes, it automatically powers off after 15 minutes of inactivity. You can turn it back on by pressing any button or rotating the dial.
How should I care for the multimeter?
Keep the device clean and dry. Wipe the case with a soft cloth slightly dampened with water. Do not use solvents or abrasive cleaners.
Is it safe to measure voltage on a live circuit?
Yes, if you observe safety precautions. Use the correct range and rating (CAT II up to 1000 V). Never connect the device to a circuit exceeding the maximum limits, and follow standard electrical safety procedures.
