5 A. Place one hand in your pocket or behind your back. B. Turn on the power. C. Connect the meter ground to the equipment ground. D. Place the positive meter lead on the test point; select for positive or negative polarity. Figure 1A.—Procedures IN ANSWERING QUESTION 1-33, REFER TO THE PROCEDURES IN FIGURE 1A. 1-33. When you measure voltages less than 300 volts, in what order should you complete the task? 1. A B C D 2. B C D A 3. C A D B 4. D C B A _________________________________ IN ANSWERING QUESTIONS 1-34 THROUGH 1-37, SELECT FROM THE MEASUREMENT COLUMN BELOW THE ANSWER THAT MATCHES THE SITUATION BEING DESCRIBED. MEASUREMENT1. Current 2. Inductance3. Resistance4. Capacitance_________________________________ 1-34. This measurement is rarely taken in preventive or corrective maintenance or testing because unsoldering is usually required. Ohm's law is normally applied to determine this value. 1-35. This is a valuable aid in locating faults during corrective maintenance, but cannot be made with power applied. Many technical manuals contain charts that indicate the test points for this measurement. 1-36. This measurement provides an indication of dielectric strength and is used to determine the power factor. 1-37. This measurement is seldom taken during troubleshooting. It can be taken using a bridge or another instrument that is primarily designed to measure another quantity; however, a conversion chart is required. 1-38. The power factor is an indication of the losses caused by which of the following conditions? 1. Excessive voltage 2. Dielectric absorption 3. Current leakage 4. Both 2 and 3 above 1-39. The Wheatstone bridge can be used for precision measurements of which of the following quantities? 1. Voltage 2. Current 3. Impedance4. Resistance
