Frequency variation with temperature

Frequency deviation from the mean as a percentage, against temperature in deg C.



Regression slopes: F1/T = -0.00 %/degC;   F3/T = -0.00 %/degC;   F5/T = -0.00 %/degC;  

Q-factor variation with temperature

Q-factor deviation as a percentage of the mean, against temperature.



Regression slopes: Q1/T = 0.01 %/degC;   Q3/T = 0.01 %/degC;   Q5/T = -0.17 %/degC;  

Resistance variation with temperature

Looking just at f3/4 and f5/4 for the underlying temperature trend, free of moisture disturbances.



Regression slopes: R3/T = -0.01 %/degC;   R5/T = 0.17 %/degC;  

Frequency variation with humidity

Frequency deviation as a percentage of the mean, against percentage humidity.



Regression slopes: F1/H = 0.00 %/%;   F3/H = 0.00 %/%;   F5/H = 0.00 %/%;  

Q-factor variation with humidity

Q-factor deviation as a percentage of the mean, against percentage humidity.



Regression slopes: Q1/H = -0.02 %/%;   Q3/H = -0.02 %/%;   Q5/H = 0.08 %/%;
