Project Objectives:
• To develop an understanding of the ohmmeter function of a DMM.
• To learn how to use the variable resistance section of the Elenco trainer.
ems Needed:
- Electronics Trainer - Digital multi-meter - 10k  resistor
- Jumper Wires - 1k  resistor - 47k  resistor
this project please use the following safety precautions when connecting meters to make resistance
easurements.
1. Disconnect the circuit from the power source.
2. Isolate the component being measured from the rest of the circuit.
3. Use the correct meter mode / function for what you are measuring. (ohms)
4. Be sure to use the appropriate range for the expected resistance.
5. When finished making measurements, be sure to turn the meter OFF.
