Performs pressure setting automatically by detecting the increase and
decrease in pressure. For example, if this function is used for a suction test,
the pressure setting will be completed by performing suction and release of
the workpiece.
Shows the minimum pressure from when the power was supplied to the
current time.
The problem of the switch output turning ON and OFF repeatedly around the
set value at high frequency due to the effect of pulsation.
A function to delay the response time of switch output in order to prevent
chattering.
The setting time from when the signal of the connected pressure sensor
reaches the set value, to when the ON-OFF output actually begins working.
Delay time setting can prevent the output from chattering.
The response time indicates when the set value is 90% in relation to the step
input.
Shows how precisely the pressure can be displayed or set.
When 1 digit = 1 kPa, the pressure is displayed in increments of 1 kPa, e.g.,
1, 2, 3, ..., 99, 100.
Function to add digital filtering to the fluctuation in the input signal.
Smooth the fluctuation of displayed value for sharp start up or fall of the
pressure.
When the function is valid, digital filtering is reflected to the ON/OFF of the
switch output.
Output chattering or flicker in the measurement mode display can be reduced
by setting the digital filter.
Shows The maximum deviation between the displayed pressure value and
the true pressure.
Indicates the colour of the number of digital display. Always green, always
red, green (switch OFF)  red (switch ON), red (switch OFF)  green (switch
ON) are available.
Indicate in how many the rated pressure range can be divided to display.
(Example: When the value can be displayed down to 0.001 MPa for the
product for 0 to 1 MPa, the resolution is 1/1000)
Displayed pressure value can be adjusted within the range of 5%R.D. (5%
of displayed value). It is used if the true pressure value is known, or to
eliminate differences between the displayed values of different instruments
that are measuring the same pressure.
Switches the switch output to ON/OFF when an error is displayed.
