Definition and terminology
Term Definition
A
Auto-preset
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.
B
Bottom value display (mode)
Shows the minimum pressure from when the power was supplied to the
current time.
C
Chattering
The problem of the switch output turning ON and OFF repeatedly around the
set value at high frequency due to the effect of pulsation.
Chattering prevention function
A function to delay the response time of switch output in order to prevent
chattering.
D
Delay time
The setting time from when the pressure applied to the pressure switch
reaches the set value, to when the ON-OFF output actually begins working.
Delay time setting can prevent the output from chattering.
digit (Min. setting unit)
Shows how precisely the pressure can be displayed or set by the digital
pressure switch. When 1 digit = 1 kPa, the pressure is displayed in
increments of 1 kPa, e.g., 1, 2, 3, …, 99, 100.
Digital filter
Function to add digital filtering to the fluctuation of pressure value. 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.
The response time indicates when the set value is 90% in relation to the step
input.
Display accuracy
Shows The maximum deviation between the displayed pressure value and
the true pressure.
Display color
Indicates the color of the number of digital display. Always green, always red,
green (switch OFF)
→
red (switch ON), red (switch OFF)
→
green (switch
ON) are available.
Display resolving power
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)
Display value fine adjustment
(function)
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.
E
Error displayed
The code number displayed, identifying the error detected by the
self-diagnostic function of the pressure switch.
Refer to "Error indication function" on page
91 for details of the errors.
Error output
Switches the switch output to ON/OFF when an error is displayed.
Refer to "List of output modes" on page
36 for operating conditions.
Refer to "Error indication function" on page 91 for details of the errors.
