Forging new generations of engineers

2. What is a Digital Multimeter?
A digital multimeter measures AC and/or DC voltage, resistance, and current in an electric circuit. It is highly accurate and displays an LCD number readout.

3. Test Leads
Test leads are used to connect the multimeter to the circuit to be tested.

4. Test Lead Connections - Voltage
Plug the RED test lead into the jack labeled V/ and the BLACK test lead into the jack labeled COM (common).

5. Ohmmeter
The ohmmeter is used to measure the resistance of a component.
POWER CANNOT be applied to the component being tested.
The ohmmeter actually applies a small voltage and uses Ohm’s law to calculate the resistance from the measured current.

6. Multimeter Right now the leads are not touching. Choose
What does the meter read?
What does that mean?
Choose 2M
200k
20k 2k
200 ohms
This section measures resistance in ohms

7. How to choose your setting
Set the meter to the next highest value beyond what you are testing.
IE: you think you have a 330 ohm resistor
What value do you set the meter to? 2M
200K
20k 2k
200

8. To measure a 220K Ohm resistor, what setting do you use?
A setting of 2M gives a reading of .222MΩ =
222K Ω which is within the tolerance for a 220 Ω resistor
Choose 2M
200k
20k 2k
200 ohms
To measure a 220K Ohm resistor, what setting do you use?
200K?
What does the meter on the right read at the 200K setting?
