What Should Be Done

For this, the following are critical:

- Wiring - The red wire from the fan must be connected to V+, and the black wire must be connected to V- or the fan will be smoked.
- The Extech clamp meter must be set at the correct setting, which is 4A DC.
- The Extech clamp meter must be zeroed in-between every measurement.

The Outcome

Both wires can be measured. If the student get's a negative number, then the wire is oriented the wrong direction in the clamp. Turn it around and retake the measurement. Negative numbers are not as accurate.

The current should be around 40 to 70 mA.
