ADC digital sphygs have a pressure sensor self test that is activated each time you power on the instrument. If the microprocessor detects anything wrong with either the pressure sensor or the chip that analyzes the readings, an error message will be displayed BEFORE measurement. If the unit beeps and displays 0, you can be confident in the instrument’s accuracy.
