Display type where each individual display character consists of up to 7 separate

(The figure "8" uses all 7 segments)
Indicate the command signal which generate vacuum.
(It is necessary to input the pressure switch)
A function of the Pressure switch to automatically setup pressure just by having
equipment hold and release a workpiece via vacuum adsorption. This function is
used in an application where vacuum adsorption of a workpiece needs to be
confirmed with a Pressure switch.
Indicates the minimum vacuum 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.
Shows how precisely the pressure can be indicated or set by the digital
Pressure switch. When 1 digit = 1 kPa, the pressure is given with an increment of
1 kPa, e.g., 1, 2, 3,..., 99, 100.
Indicate that the vacuum pressure during adsorption is monitored and ON and
OFF of the ejector is automatically controlled.
With the self-diagnosis function given to the Pressure switch, it indicates that
there is a failure which could cause a switch failure.
Refer to "Fine adjustment of display value".
An indicated pressure value can be adjusted within the range of ±5% R.D.
(±5% of the indicated value). It is used if a true pressure value is known or to
correct the difference of an indicated value of the measurement equipment
nearby that measures the same pressure as the Pressure switch.
Abbreviation for full span and full scale; means the maximum fluctuation range
of the Pressure switch rated value.
A mode in which setting of functions is performed. It is a separate menu from the
pressure setting.
If any function settings needs to be changed from the factory default, each setting
can be selected with "F ".
The setting items are: display color, operation mode, output type, response time,
display resolution, display value fine adjustment, use of auto preset, use of power
saving mode, and use of PIN number. Refer to page 24 for a l
modes
that can be selected.
Difference between the points at which the Pressure switch is turned on and off.
