Clarke Digital Multimeter - CDM10C - 5 Function

The CDM10C can measure up to 600V for both AC and DC voltage.

The product description specifies measurement for DC Current only (20µA to 10A). It does not support AC current measurement.

Set the dial to the diode test symbol (often looks like a triangle with a line). Connect the red probe to the anode and the black probe to the cathode of the diode. A good diode will show a voltage drop (typically 0.5-0.8V); a shorted diode will show near 0V, and an open diode will show 'OL'.

No, the Clarke CDM10C does not feature auto-ranging. You must manually select the appropriate measurement range using the rotary dial.

The multimeter is supplied with a folding stand, test probes, and a 9V battery.

It comes with a removable thick rubber casing for protection against impacts. Always ensure the correct function and range are selected to avoid overload. Store it safely when not in use.

The resistance measurement ranges are from 200 Ohms to 2 Megaohms (2,000,000 Ohms).

This indicates an 'Over Limit' or 'Open Loop' condition. The measured value exceeds the selected range. Select a higher range for the current measurement or check for continuity issues.

Ensure the test probes are securely inserted into the correct jacks and making good contact with the circuit. Check if the battery is low and needs replacement. Verify the correct function and range are selected.

Check battery level; a low battery can affect accuracy. Ensure the selected range is appropriate for the measurement. Make sure test leads are not damaged and are firmly connected.

Check if the 9V battery is installed correctly and has sufficient charge. Replace the battery if necessary.
