Frequently Asked Questions - C-4 Electronics International
How do I change the battery in my C-4 multimeter?
Turn off the meter, remove the screw on the back cover, lift the cover, replace the 9V battery with a new one, and reattach the cover. Ensure polarity is correct.
What does the symbol "OL" mean on the display?
"OL" stands for Overload. It indicates that the input exceeds the selected range. Switch to a higher range or ensure the measurement is within the meter's capabilities.
Can I measure AC current with the C-4?
Yes, the C-4 can measure AC current up to 10A. Insert the black lead into COM and the red lead into the 10A jack. Set the dial to the appropriate AC current range.
How do I test continuity?
Set the dial to the continuity function (usually a diode/continuity symbol). Connect the test leads across the circuit. A beep will sound if continuity exists (resistance below ~50Ω).
What is the maximum voltage the C-4 can measure?
The C-4 can measure up to 600V AC/DC. Exceeding this may damage the meter and pose a safety hazard. Always start with the highest range.
How do I calibrate the C-4?
Calibration should be performed by a qualified technician using a known reference. Refer to the service manual for detailed procedures. Annual calibration is recommended.
Why does the display show a negative reading?
A negative reading indicates that the test leads are reversed. Swap the red and black probes to obtain a positive reading.
Can I use the C-4 to measure temperature?
Yes, if your model includes a thermocouple probe. Set the dial to the temperature function (usually labeled TEMP or °F/°C). Insert the thermocouple into the input jacks.
What should I do if the meter does not turn on?
Check the battery first. If the battery is good, inspect the battery contacts for corrosion. Also ensure the dial is not in an off position. If still not working, contact support.
Is the C-4 safe for use in high-energy circuits?
The C-4 is rated CAT II 600V and CAT III 300V. It is suitable for most household and industrial circuits, but not for high-energy environments like substations. Always follow safety guidelines.
