Calibrate Load Cell for Early Winter 2023 Hotfire operations. #31

Closed harrisonCassar closed 1 year ago

harrisonCassar commented 1 year ago

Motivation/Description

Currently, we do not have any recent calibration values for our Load Cell. We need a Load Cell (well-calibrated) for 11/5 Hotfire operations!

Work To-Be-Done

Support Load Cell calibration, computing calibration coefficients, and updating ADC source code with results.

Similar to PT calibration process done in #10.

This will tentatively be done during the beginning of winter quarter with Emily and Logan (Electronics and VE Leads).

This was completed but never closed. All work has been completed.

For completion sake, here's the complete calibration values (load cell is represented in the last column):

char labels[10][100] = {"lox_fill", "fuel_tank", "cc", "low_press", "lox_tank", "pneumatics", "lox_manifold", "fuel_manifold", "high_press", "load_cell"};
double a[10] = {245.29, 249.93, 247.55, 247.4, 248.81, 47.864, 251.65, 253.77, 1248.9, 462};
double b[10] = {-266.93, -271.7, -261.56, -274.58, -260.28, -61.123, -282.75, -272.97, -1233.3, 0.954};
