  • Pressure is checked in 50 mmHg increments from 0–300 mmHg, and in 50 mmHg increments down again. The data at each testing interval between 0–250 mmHg going up have been combined with the data going down. Overestimates and underestimates include any difference of 0.1 mmHg or more from the reference device.
