Question 1 of 12
Interpret the pressure measurement displayed by this gauge mechanism, assuming a gauge accuracy of $\pm$ 1
How low and how high could this pressure actually be, given the stated accuracy of this gauge?
Reveal answerPressure = 3750 PSI $\pm$ 60 PSI
This means the actual pressure could be as low as 3690 PSI or as high as 3810 PSI.

Question 3 of 12
Interpret the pressure measurement displayed by this gauge mechanism, assuming a gauge accuracy of $\pm$ 0.5
How low and how high could this pressure actually be, given the stated accuracy of this gauge?
Reveal answerPressure = 560 PSI $\pm$ 5 PSI
This means the actual pressure could be as low as 555 PSI or as high as 565 PSI.
