Output Operation mode
Change the output operation mode to change pressure detection method.
ON:
OFF:
■ Hysteresis
• Set the hysteresis for pressure detection
directly.
• Setting: Pressure detection level (ST1,
ST2), Hysteresis (HYS1, HYS2)

■ Hysteresis - Window
comparison output
• It is available both hysteresis mode
and window comparison output mode
operations.
• Setting: Pressure detection level (ST1),
Hysteresis (HYS1), High limit (HIGH), Low
limit (LOW)

■ Forced output control
• It displays the present pressure with
forcibly holding comparing output OFF
regardless of setting value.
• Manual ON/OFF for OUT1/2 is possible
by [M], [▼] or [▲] key during forced
output control operation.

■ Window comparison output
• It detects pressure at the desired range.
• Hysteresis is fixed as min. display interval.
• Setting: High limit (HI1, HI2), Low limit

Zero-point Adjustment
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 affects
analog output.
• For precise measurement, execute zero-point adjustment periodically.
Maximum / Minimum Value Monitoring
Time
In order to identify abnormal conditions of the system that are not easily identified 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'.

Max. memorized input
Display / Output Scale
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).

Response Time
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 filter increase, so stable
measurement is possible, but the measured value may differ from the actual input
value.
