2 3. HANDS ON 3.1 DIODE CHECK Set the Multimeter in Diode mode by pressing Shift and then Fre q . The Multimeter will display the voltage drop across the diode when connected as shown in Figure 1. Write down the values for each diode. Connect the diode to the DMM as shown in Figure 1 (the striped end toward the black cable), when the diode is oriented in the right direction you will hear a beep FIGURE 1 3.2 BRIDGE RECTIFIER Remember to set your Function Generator to “High Z”
