2 colours are used to indicate a value, which change according to the output
status.
When "8" is shown on the display. It is called 7-segment because 8 consists of
7 pieces of "- (segments)".
Refer to "Analogue output (function)".
A function to output the voltage or current in proportion to the pressure.
Refer to "Analogue output (function)".
A function to automatically set up the pressure by having equipment hold and
release a workpiece via vacuum adsorption. This function is used in an
application where vacuum adsorption of a workpiece is confirmed by a
Pressure switch.
Displays the minimum pressure reached up to that moment.
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.
A Pressure switch whose settings are copied to when using the copy function.
A function to copy a pressure setting value and function setting (excluding fine
adjustment of display value).
A Pressure switch whose settings are copied when using the copy function.
Shows how precisely the pressure can be displayed or set by the digital
Pressure switch. When 1 digit = 1 kPa, the pressure is given with an increment
of 1kPa, e.g., 1, 2, 3, ..., 99, 100.
With the self-diagnostic function of the Pressure switch, this indicates that there
is an error which could cause a switch failure.
Refer to "Fine adjustment of display value".
A displayed pressure value can be adjusted within the range of ±5%R.D.
(±5% of the displayed value). It is used if a true pressure value is known or to
correct the difference of a displayed value of the measurement equipment
nearby which measures the same pressure.
Abbreviation for full span or full scale; this means the maximum fluctuation
range of the Pressure switch rated value. For example, when the output
voltage is 1 to 5[V], the F.S. will be 5-1 = 4[V]. (Ref: 1%F.S. = 4 × 0.01 = 0.04[V])
This is a mode in which each function is set up, and is a separate menu from
the pressure setup. If the setting needs to be changed, "F∗", each item can be
set up. The items to be set up are: display colour, operation mode, output type,
response time, display resolution, fine adjustment of display value, auto preset,
power-saving mode and security code number.
The difference between the pressure switch ON and OFF points, used to
prevent chattering.
Refer to "List of output modes" on page 29.
