14 July 2008Back to lab after meeting → worked with Labview and Maex to fix apparatus Dan came to the lab around 6pm to help me with the system
Diagrams of circuits on pg __ of my (Rima’s) notebook Daniel Ludwig came to lab *helped me set up amplifier with power source Diagrams of the AD524 (CD amp chip) and circuit set-up on power supply on page__ of my (Rima’s) notebook Daniel drew simple diagram of our two resistors in series on page __ of my (Rima’s) notebook Equations that set parameters of our system: i=V/(R1+R2) V1= iR1 V2= iR2 V(input)=V(R1/[R1+R2]) With R1 being the comparison resistor and R2 being the solution of cells (or whatever is being measured)
Our test: R1= 9.91kΩ R2= 477.7kΩ V(input)= 1.02V Saved as “test” under Team resistance documents
Initially, the circuit was wired under the consideration that it was under the property RSE (reference single ended) because the circuit was wired to a single ground However, Maex keeps switching to Differential, so Dan helped me re-wire the system according to differential To do this we wired each input with the respective input ground across from it (0→8, 1→9, 2→10, as described in meeting with Professor Daniels) Labview program
To potentially reduce noise (fluctuations)
Apparatus is now ready for testing Made 2 pVJ4 cultures for dilutions tomorrow Incubate 8:20pm |
