• The displayed pressure when the pressure port is left
open is adjusted to zero.
• The sensor will automatically enter the sensing
mode when power is supplied.
• Let the pressure port be at atmospheric
pressure (i.e., no applied pressure condition),
and press, simultaneously, the UP and
DOWN keys continuously.
• is displayed and, when the fingers are
released, zero-point adjustment is completed
and the sensor returns to the sensing mode.
• Pressure ‘Unit’, ‘Display’, and ‘Output mode’ of the outputs
are set.
• In the sensing mode, press key while
pressing UP key.
• Initial setting is displayed.
• If sensor is being used for the first time,
is displayed.
• The settable digit blinks.
• The settable digit changes when UP key is
pressed and the setting is changed when
DOWN key is pressed.
•
‘NO / NC’, ‘Display cycle’, ‘Response time’ and ‘Pressure range’ are set.
• In the sensing mode, press both DOWN key
and key simultaneously.
• The setting item and the setting condition are
displayed alternately.
• The setting item changes when UP key is
pressed.
• The set condition of each item changes when
DOWN key is pressed.
• Sets output to Set Value 1 to 3 (P-1 to P-3).
• Press the key in sensing mode.
•
The mode changes in the order Set Value 1
(P-1) setting mode, Set Value 2 (P-2) setting
mode and Set Value 3 (P-3) setting mode each
time the key is pressed.
• If key-protect has been set, make sure to release key-protect before operating the keys.
(Please refer to ‘Key-protect function’ on p.787 for the procedure.)
• Set Value 1 (P-1) and Set Value 2 (P-2) can be made common for all the output modes.
• The setting of Set Value 2 (P-2) with respect to Set Value 1 (P-1) can only be towards the high pressure side in case of
the positive pressure type sensor and only towards the high vacuum side in case of the vacuum pressure type sensor.
• The conditions which are set are stored in an EEPROM. Kindly note that the EEPROM has a life span and its guaranteed
life is 100,000 write operation cycles.

• Use the UP key and DOWN key
to check Set Value 3 (P-3).

Note: Set Value 3 is only displayed when automatic sensitivity setting mode
has been set. Furthermore, if Set Value 3 is between Set Value 1 and
Set Value 2, the UP key and DOWN key can be used to correct it.
