Using a Digital Multimeter Setup: A digital multimeter, power supply, grounding strap, safety glasses, and a bread board with multiple resistors and diodes. Properly attach the grounding strap at both ends. Wear safety glasses. Safely set up a digital multimeter to the output of a power supply by attaching the red meter lead to the +V out and the black lead to V out. Using a digital multimeter, measure volts. Check the correct voltage range (V--- when measuring DC or V ~ when measuring AC). Connect the test leads correctly. When measuring DC, the black test lead should be connected to V-ohms, and the red test lead should be connected to COM. When measuring AC, the black test lead should be connected to COM, and the red test lead should be connected to V-ohms. Read the voltage reading on the display. Using a digital multimeter, measure current. Select the correct current range. (A --- when measuring DC or and A ~ when measuring AC) Connect the test leads correctly in series with the circuit.. The red lead should be connected to the ma jack for input up to 200 milliamps and to the 10A jack for input up to 10 amps. Read the current reading on the display. Using a digital multimeter, measure resistance. Prepare to measure the resistance by discharging the capacitors in the circuit. This can be done by shorting across the terminals of each capacitor with a jumper wire. Select ohms on the multimeter. Connect the test leads correctly. The black test lead should be connected to COM, and the red test lead should be connected to V-ohms. Read the resistance reading on the display. Troubleshoot any problems.

Using an Analog Multimeter Setup: Setup: An analog multimeter, power supply, grounding strap, safety glasses, and a breadboard with multiple resistors and diodes. Properly attach the grounding strap at both ends. Wear safety glasses. Safely set up an analog multimeter to the output of a power supply by attaching the red meter lead to the +V out and the black lead to V out. Using an analog multimeter, measure volts. Set the function switch to +DC or AC. Set the range switch to the correct range position. When in doubt, start with the highest and work down. If measuring DC voltage, connect the black test lead to the negative side of the circuit being measured and the red test lead to the positive side of the circuit. If testing AC, connect the test leads across the voltage source (in parallel with the circuit). Read the voltage back on the appropriate DC or AC scale. Using an analog multimeter, measure current. Set the function switch to +DC. Plug the black test lead into the (common) jack and the red test lead into + 50 milliamps or 10 amps. Set the range switch of the appropriate range position. Open the circuit in which the current is being measured. Connect the multimeter in series with the load across the voltage source. Connect the red test lead to the positive side and the black test lead to the negative side of the part of the circuit you are measuring. Do not connect the test leads directly across voltage when the meter is being used to read currents. Read the current on the black DC scale. Convert the number according to the range being measured. (Use 0 to 50 figures to read directly in microamperes. For the 1mA range, use the 0-10 figures and divide by 10. For the 10mA range, use the 0-10 figures and multiply by 10. For the 500mA range, use the 0-50figures and multiply by 10. Using an analog multimeter, measure resistance. ((Mod 33204, pp. 23-24)) Ensure that no power is flowing to the circuit. Disconnect the component from the circuit before measuring its resistance. Set the range switch to the appropriate range position. Set the function switch to either DC or +DC position. Adjust the zero ohm control for each resistance range. Check that the ohms range will not damage any of the semiconductors. Rotate the function switch between the two DC positions to reverse polarity in order to determine if there is a difference between the resistance in the two directions. Measure resistance of the component. Troubleshoot any problems. Using a group of diodes, identify the damaged or bad diode. Using a group of resistors, identify their values with the digital multimeter.
