Customizes the scale of display / output value from rated output range. If the measured
input is a, b, and the arbitrary values to be displayed are A, B, the display / output value
are outputted for input a and b linearly (a = A, b = B).

In order to identify abnormal conditions of the system that are not easily identied or
to diagnose the max. / min. input that has occurred, save the value and notify it.
• When the memorized max. / min. pressure is higher / lower than the rated pressure, it
displays 'HHHH' / 'LLLL'.

With the pressure port open, the current pressure value on display is set to zero forcibly
by removing deviations from opening the pressure port. Zero-point adjustment aects
analog output.
• For precise measurement, execute zero-point adjustment periodically.

Input
Prevents chattering of the output by changing the response time of the control output
and pressure display value.
When the response time is longer, the number of digital lter increase, so stable
measurement is possible, but the measured value may dier from the actual input
value.
Auto shift
The judgment level is corrected by applying the standard pressure which is set
when external input signal is applied.
• Correction set value ST1 = ST1 + SH.IN
Correction set value HYS1 = HYS1 + SH.IN
SH.IN is the reference pressure set by Auto shift input.
