P.3

Part B - Procedures 1. Switch on the variable DC power supply and adjust the DC output voltage to 10V. Figure 5 shows a typical DC power supply and the symbol used to represent it. OO oo Figure 5 (a) variable DC power supply (b) Its symbolic representation + DMM Figure 6 Connection of DMM to variable DC power supply. Connect the probes of the DMM to the output terminals of the DC power supply as shown in Figure 6. Meter reading Hot 9. 94 v Reverse the test probes and note the new reading, including its sign. Meter reading toy - 9.95 v + Repeat 2 and 3 at E = 1.5V. Indicate meter readings and your observation regarding the range of the DMM, i.e., did your meter automatically change range or did you have to do it manually. Use the manual changing range function to record the indication of 1.5V at three different range settings: Range setting 20V 200V readings 1. 473 V
