3 Pressure value setting

For the case when output mode is set to either hysteresis

mode (

), window comparator mode (

) or dual output

mode (

).

• ‘Set Value 1 (P-1)’ and Set Value 2 (P-2)’ of the com-

parative outputs are set.

• Press

key in the sensing mode to set to Set

Value 1 (P-1) set mode.

• Enter Set Value 1 (P-1) using

key and

key.

• Then, press

key to set to Set Value 2 (P-2)

set mode.

• Enter Set Value 2 (P-2) using

key and

key.

• Then, press

key to set to sensing mode.

2 Initial setting

• Pressure ‘Unit’, ‘Display’ and ‘Output mode’ of the

comparative outputs are set.

• In the sensing mode, press

key while press-

ing

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

key is

pressed and the setting is changed when

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.801 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.

• Set Value 3 (P-3) is automatically set to the mid-value of Set Value 1 (P-1) and Set Value 2 (P-2).

(When setting the pressure value for the automatic sensitivity mode)

• 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.

For the case when output mode is set to automatic sensitivity

setting mode (

).

• ‘Set Value 1 (P-1)’, ‘Set Value 2 (P-2)’ and ‘Set Value 3

(P-3)’ of the comparative outputs are set.

• Press

key in the sensing mode to set to Set

Value 1 (P-1) set mode.

• Within the required permissible pressure range,

having created a pressure state which is nearest

to the atmospheric pressure, press

key to

enter Set Value 1 (P-1).

• Then, press

key to set to Set Value 2 (P-2)

set mode.

• Within the required permissible pressure range,

having created a pressure state which is nearest

to the high pressure end (for a positive pressure

type sensor) or the high vacuum end (for a

vacuum pressure type sensor), press

key to

enter Set Value 2 (P-2).

• Then, press

key to set to Set Value 3 (P-3)

set mode.

• Check Set Value 3 (P-3) which has been set

automatically. When Set Value 3 (P-3) is to be

changed, enter Set Value 3 (P-3) using

key

and

key.

• After checking and setting, press

key to set to

sensing mode.

1 Zero-point adjustment

• 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 increment and decrement

keys continuously.

•

is displayed and, when the fingers are

released, zero-point adjustment is completed and

the sensor returns to the sensing mode.

• The automatically set Set Value 3 (P-3) can be manually changed

to a value between Set Value 1 (P-1) and Set Value 2 (P-2).

• If using the window comparator mode, set the pressure value

so that there is a difference of 3 digits, or more, between Set

Value 1 (P-1) and Set Value 2 (P-2). No output will be possible

with a 0 to 2 digit difference.
