Zero-point adjustment
The displayed differential pressure when the pressure port is left
open is adjusted to zero.
Set to sensing mode
The sensor will automatically enter the
sensing mode when power is supplied.
The figure on the left shows the display when
the pressure unit is set to 'mmH
'kPa'.
Perform zero-point adjustment
Let the pressure ports (Hi-port and Lo-port)
be at atmospheric pressure (i.e., no applied
pressure condition), and press, simultane-

Your set data is registered and the sensor
enters into the sensing mode.
Since the initial conditions which have been
set are stored in an EEPROM, they are not
erased even if the power supply is switched
