The reliability of a measuring device refers to its ability to consistently produce the same results under the same conditions, even if those results are not accurate. In this case, since the device consistently overestimates blood pressure by the same amount (10 units) for every assessee, its reliability is not affected by the passage of time. Accuracy (the device's ability to measure the true value) is compromised, but reliability (consistency of measurement) remains unchanged.
