Question

30%te Q1.- Using a 3% digits DMM and a VOM to measure a 12V voltage source and the results are recorded in the following Table 1:4 VOM 12.1ve 11.9ve 12.2ve 11.5ve 11.8V DMM 12.02ve 11.97ve 11.98ve 12.04ve 11.95ve Tahle Accuracy of the meter: VOM (+0.5% of 50V full-scale reading) DMM (0.3% of reading + 1 digit) Tahle 1 (1) Draw the circuit diagram with the voltmeter connected. (ii) Compare the two sets of data in Table 1 in terms of accuracy and precision (iii) Find the accuracy of VOM in terms of guaranteed limit if the range of VOM is 50V? (iv) Find the accuracy of DMM in terms of guaranteed limit if the true value voltage of the power pack is 12V that the DMM will be used to measure? (v) Compare the accuracy of VOM and DMM. Which one has a higher accuracy? الم
