Measuring DC Current

• 3. Rotate the dial to the maximum setting on the
  DCA Range
• 4. Make the connection to the power source to
  send a current through the circuit.

7
Measuring DC Current

• 5. Reduce the DC Amp setting step-by-step until a
  reading is obtained.
• 6. Record the reading.
• What if the reading is in mAmps?
• Convert the reading to Amps.

8
Measuring DC Current

• 7. Disconnect the wire from the power source.
• 8. Rotate the meter dial to off.

Measuring DC Voltage

• 1. Complete the hookup without making the final
  connection to the power source.

11
Measuring DC Voltage

• 2. Connect the leads of the meter across the
  region you wish to know the voltage.

12
Measuring DC Voltage

• 3. Rotate the dial to the maximum setting on the

• 4. Make the connection to the power source to
  send a current through the circuit.

13
Measuring DC Voltage

• 5. Reduce the DC-Volt setting step-by-step until
  a reading is obtained.
• 6. Record the reading.
• 7. Disconnect the meter wires from the circuit.
• 8. Rotate the meter dial to off.

17
Measuring Resistance

• 1. Connect the meter leads, one to each end of a
  resistor.
• 2. Rotate the meter dial in the resistance range
  until a reading is obtained.
• 3. Record the reading.
• 4. Rotate the meter dial to off.
