Function Details
Copy function (F97)
L
The settings of the master sensor can be copied to the slave
sensors, reducing setting labour and minimizing the risk of setting
mistakes.
The set value can be copied to up to 10 sensors simulta-
neously. (Maximum transmission distance: 4 m)

1) Wire as shown in the fi gure above.
2) Select the slave sensor which is to be the master, and change it
into a master using the buttons. (In the default setting, all sensors
are set as slaves.)
3) Press the button on the master sensor to start copying.
Analogue free span function (F5)

For the displayed value, the analogue span point (5 V, 20 mA) can
be changed within the rated pressure range of 10 to 105 % ∗

The F in ( ) shows the function code number. Refer to the operation
manual for details on operation procedures and function codes.
Auto-shift function (F5)
M
When there are large fl uctuations in the supply pressure, the switch
may fail to operate correctly.
This function compensates for such supply pressure fl uctuations. It
measures the pressure at the time of auto-shift signal input and uses
it as the reference pressure to correct the set value on the switch.

The above is an example in hysteresis mode. On-off points are
similarly rectified in window comparator mode. Outputs that
enable the auto-shift function can be changed via the settings.

Auto-shift zero
The basic function of auto-shift zero is the same as that of auto-
shift. However, it corrects values on the display based on a
pressure value of " ", which is set as the reference value when
auto-shift function is selected.
