Unformatted text preview: Dalhousie University Department of Electrical and Computer Engineering ECED 310E} Electromechanics Lab 1 Introduction tc Lachlt Data Acquisition System Object : To become familiar with the LabVolt Data Acquisition System for laboratory measurement. Activity 1) Construct the following circuit with appropriate instrumentation to measure V5, V“ V. and I. Apply 120 V and record readings. Tti'r 2) With your instrumentation in place _1 I ccnnect the Lahh'olt DA] unit to make 3mg; the same measurements. Be carefirl with polarities. fine a I m 3} On the LabVolt screen open the V‘ o " Oscilloscope, Phasor Analysis and Metering udndcws. Access and record your data. 4) Look at the ‘sccpe window and measure the phase shift (in seconds) between Va and 1. Convert this to degrees and check for appropriatmess. 5) Save your data for V5, VI. V1 and l in a spreadsheet and copy and paste this intc Excel. 6} Observe the phasor analysis screen and determine if the phascrs are as you expected them fi'om calculations. 1') Use a print screen to dump the Phasor plot into MS Word. 3) Observe the Metering Screen. Create two new meters to measure power factor and impedance at the source. 9) Connect the following circuit. Use your DAI to plot the admittance locus as seen by the source as you vary the circuit capacitance from t} - cc- [or as close as you can come). Report Write up a one page summary of your findings and include the various screen shots and excel data sheets that you have created. ...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
