When measuring AC voltage with the analog multimeter the range should be set to a lower than expected range a higher than expected range C. any voltage range selection is ok a. b. The highest AC current that the analog multimeter can handle is this meter cannot be used to measure AC current. b. 10 mA 100 mA a. C. d. 500 mA e. 10 A The zero ohm adjust knob is used to a. set the pointer to infinity resistance on the scale b. set the pointer to zero resistance on the scale set the pointer to zero for all types of readings 4. С. To measure AC voltage with the digital multimeter a. make sure you are set to the correct range (0-250v) b. zero the meter first set the function switch to V С. 6. If the amperage readings register very low on the Amprobe clamp-around meter or the Fluke T5 a. record the reading as this meter reads accurately at all positions of the scale. b. wrap a wire around the clamp several times and connect in series with the load, divide reading by number of turns. c. nothing can be recorded about this current reading As used in this lab, the digital multimeter gave a Amprobe clamp-around meter. accurate reading than the a. more b. less about the same C. 3. 5.

According to Blondel's theorem, the total power is measured with one less number of wattmeters than the number of wires present in the system. So, a single-phase and two-wire system will require one wattmeter and a single-phase and the three-wire system …
