Clarke 4500007 CDM20 Digital Multimeter F.A.Q.

How do I measure AC voltage using the Clarke 4500007 CDM20 Digital Multimeter?

To measure AC voltage, turn the multimeter knob to the V~ setting. Insert the black probe into the COM terminal and the red probe into the VΩmA terminal. Touch the probes to the circuit terminals and read the voltage on the display.

What should I do if the multimeter display is not turning on?

Ensure that the battery is properly installed and has charge. If the problem persists, check for any loose connections or consider replacing the battery.

Can the Clarke 4500007 CDM20 measure DC current?

Yes, to measure DC current, switch the dial to the A setting, use the appropriate port for the expected current range, and connect the multimeter in series with the circuit.

How can I test the continuity of a wire with this multimeter?

Set the multimeter to the continuity test mode, indicated by a diode symbol. Insert the probes into the COM and VΩmA terminals, then touch the probes to both ends of the wire. A beep indicates continuity.

What precautions should I take when using the multimeter?

Always start with the highest range for unknown measurements, ensure the multimeter is set to the correct measurement type, and never exceed the maximum input limits.

How do I replace the battery in the Clarke 4500007 CDM20?

To replace the battery, remove the protective case, unscrew the back cover, replace the old battery with a new 9V battery, and reassemble the multimeter.

What should I do if the multimeter is not measuring resistance correctly?

Ensure the probes are properly connected and the device being measured is disconnected from power. Check the multimeter settings and try recalibrating if necessary.
