McLaren Applied Technologies - composite materials for the solar panels  Inwhen the main development phase started, Astrium took over responsibility for programme management, and Leicester assumed responsibility for mission management which involved the preparations for the operations post launch and the operations control centre.
Alternators - Off car testing report. After we removed the rear cover, the regulator and the brush holder on the alternator, we were able to carry out tests for the rotor winding to ground and the rotor winding internal resistance test.
In the rotor winding to ground test, we are testing to see if there is a circuit butween the rotor shaft and the slip ring. There should not be a circuit here and the meter should read infinity, when the meter is set to 2k.
If there is a circuit here, it means the rotor winding is shorting to earth, and will need to be replaced. On the rotor winding internal resistance test, we are testing to see if there is a circuit between the two slip rings.
There should be a circuit between the two rings, and with the ohms meter set to ohms, we should get a reading between 2 and 6 ohms.
In my test we got 3 ohms which is a pass. The ohms meter did not have any internal resistance I did not have to subtract it from the reading. If there is no circuit between the slip rings, they need to be replaced.
To carry out the next tests, I had to remove the rectifier, and the housing of the alternator so that we could access the stator winding terminals. We tested the internal resistance in these by connecting the negative of the meter to the common stator winding terminal.
The specifications of the resistance should be between 0 and. I tested them all and found they had a resistance of. The next test was the stator winding to ground test. This is where we test to see if there is a circuit between the stator winding and ground.
We test this by connecting the positve of the meter to the common stator terminal and the negative of the meter to the body of the alternator. My test read infinity so that is a pass.
Next we tested the rectifier positive diodes. The rectifier is what turns the AC current produced by the alternator into DC current. To do this we put the negative lead onto the main terminal and then the positive lead onto each of the four p-terminals.
The readings for the meter should be between. The next test we put the positive lead onto the main terminal and the negative lead on the p-terminals. The meter should now read infinity, and it did so that is a pass.
The next test was to test the rectifier negative diodes. To do this we set the meter to diode test mode. The negative lead gets put onto the E terminal and the positive lead onto each of the p terminals.
The meter should read infinity, which it did, so that was a pass. The positive lead was then put onto the E terminal, with the negative lead onto each of the p terminals. The meter should have read between.
I got readings between. The next test was to test the voltage regulator.Robert Mueller on Capitol Hill in (Yuri Gripas/Reuters) The same logic that spared FBI and Justice Department officials harsher treatment in Michael Horowitz’s report should inoculate the.
The components used to construct digital logic probe are manufactured in integrated circuit form. their encouragements and their support during the preparation of this project grupobittia.com provides various methods and techniques suitable for a variety of logic probe applications and construction.
Experiment 5: Basic Digital Logic Circuits In-Lab Procedure and Report (30 points) Before starting the procedure, record the table # you are working at in your Lab Report. Once a fault is located in the circuit by your Logic Probe, it must next be determined whether the fault is in the IC or in some short external to the node.
For example, if an output from a gate is always low, either the gate is bad or the printed circuit track to the node is shorted to the logic low.
