The deviation between displayed pressure value and the true pressure.
The colour of the digital display. There are four choices: normally green, normally
red, green (off) to red (on), and red (off) to green (on).
The LED that turns on when the switch output is on.
Insulation resistance of the product itself. The resistance between an electricical
circuit and the pressure switch body.
How fine the rated pressure range can be segmented. (Example: If a product for 0
to 1 MPa can indicate pressure by 0.001 MPa, the display resolution is 1/1000.)
The unit of pressure used on the display.
Refer to "Residual voltage".
A function that locks the setting buttons so that no accidental setting changes can
be made.
Refer to "Max. load impedance".
Manual pressure set up without using auto preset. This term is used to
distinguish from the pressure set up using auto preset.
The maximum value of applied voltage available to the output wire of the NPN
output.
The maximum current available to the output wire of the switch output.
The maximum (minimum) load (resistance value and impedance) which can be
connected to the output (output wire) of the analogue current output.
The condition in which the pressure is detected and displayed and the switch
output is operating. (Refer to "Measurement mode" on page 19.)
Refer to "digit".
The switch output operation in which the switch is turned on when pressure
equal to or greater than the set value is detected. In the (hysteresis mode)
window comparator mode, it is the operation in which the switch is turned on
when pressure is within the switch output range (P1L to P1H or P2L to P2H).
(Refer to "List of output modes" on page 26).
The switch output which uses the NPN transistor for output.
There are two choices, hysteresis mode and window comparator mode.
A restriction.
The resistance value of a component between the voltage output element and
the analogue voltage output. It is indicated as a resistance value which is
converted in accordance with the condition in which resistance is directly
connected to the voltage output element. There may be an error in the output
voltage depending on this output impedance and the input impedance of
customers' equipment. (example: If the Pressure switch with output impedance
of 1 kΩ is connected to the A/D converter to detect the analogue output of 5 V,
the detected voltage by the A/D converter becomes 5(V) × 1(MΩ)/(1(kΩ) +
1(MΩ)) ≒ 4.995(V), and there is an error of approximate 0.005 V).
The operation type of the switch output. Either normal output or reversed output
can be selected. (Refer to "List of output modes" on page 26).
