Function Details
C
Display calibration function (F 6)
D
Peak and bottom display function
E
Key lock function
This function prevents incorrect operations such as accidentally
changing the set-value.
F
Zero-clear function
This function clears and resets the zero value on the display of
measured pressure.
For the pressure switch with analog output, the analog output shifts
according to the indication.The indicated value can be adjusted
within
±
7% F.S. of the pressure when ex-factory. (ZSE40AF (for
compound pressure)
±
3.5% F.S.)
B
Auto-preset function (F 4)
Auto-preset function, when selected in the initial setting, calculates and stores the set-value from the measured pressure.
The optimum set-value is determined automatically by repeating vacuum and break with the target work piece several times.
Fine adjustment of the indicated value of the pressure sensor can be
made within the range of
±
5% of the read value.
(The scattering of the indicated value can be eliminated.)

Formula for Obtaining the Set-Value
A
Copy function (F97)
The settings of the master pressure switch can be copied to the slave pressure switches.
This can reduce the labor for setting and prevent the entry of incorrect set-values.
The set-value can be copied to up to 10 switches simultaneously.
(Maximum communication distance 4 m)
1) Wire as shown in the left figure.
2) Select the slave switch which is to be the master, and
change it into a master using the buttons. (In the default
setting, all switches are set as slaves.)
3) Press the button of the master switch to start copying.
This function constantly detects and updates the maximum
(minimum) value and allows to hold the maximum (minimum)
pressure value.
When the buttons are simultaneously pressed for 1 second or
longer, while “holding”, the hold value will be reset.
