This display shows air pressure, deflation rate, systolic (maximum) pressure, diastolic (minimum) pressure and pulse (in auto mode only). There is also a second numeric display with extra large digits, for an even easier read. The Automatic inflation of the E-SPHYG 2 9002D to pre-set levels simplifies use. This blood pressure monitor's ECV (Electronic Control Valve) precisely controls deflation at one of three pre-established rates. This helps to make the readings accurate (within 3mmHG). It takes about one minute to get an accurate reading on the E-SPHYG 2 9002D. This blood pressure monitor has both a rechargeable battery (which provides about two hundred measurements per charge) and an AC adapter included. The ADC E-SPHYG 2 9002D has a cuff size of 10.28 inches to 16.1 inches, and so is for use by adults.
