Term Definition
P
Peak value display (mode)
Shows the maximum pressure from when the power was supplied to the
current time.
Power saving mode
Operating mode in which the digital display turns off and power consumption
is reduced.
Pressure setting
The set pressure value that determines the point at which the product turns
ON and OFF.
Proof pressure
Pressure limit that if exceeded will result in mechanical and/or electrical
damage to the product.
R
Rated pressure range
The pressure range within which the product will meet all published
specifications.
Values outside of this range can be set as long as they are within the set
pressure range, but the specifications cannot be guaranteed.
R.D.
Current read value
For example, when the display value is 1.000[MPa],

5%R.D. is

5% of
1.000 [MPa], which becomes

0.05 [MPa]. When the display value is
0.800 [MPa],

5%R.D. is

5% of 0.800 [MPa], which becomes

0.04 [MPa].
Repeatability
Variation in repeated measurement of pressure display or ON-OFF output
point when the pressure changes at 25 centigrade.
Residual voltage
The difference between the ideal ON voltage and the actual voltage when the
switch output is on. Varies with load current. Ideally should be 0 V.
Resolution Refer to "Display resolution".
Reversed output
One of the switch output types. In hysteresis mode the switch output is turned
ON when pressure less than or equal to the switch output set value is
detected. In window comparator mode, the switch output is turned ON when
pressure is outside the switch output set values (n1L to n1H) is detected.
(Refer to the "List of output modes" on page
32 )
Ripple A type of chattering.
S Set pressure range The pressure range that can be set for switch output.
Switch output Sometimes referred to as "ON-OFF output".
U
Units selection function
A function to change the units in which the measured pressure value is
displayed. The display units can only be changed if the product is equipped
this function. It is not possible to purchase the product with this function if the
product is used in Japan.
The product for Japan is displayed in SI only.
W
Window comparator mode
An operating mode in which the switch output is turned on and off depending
on whether the flow is inside or outside the range of two set values.
(Refer to the "List of output modes" on page
32 )
Withstand voltage
A measure of the product’s resistance to a voltage applied between the
electrical circuit and case. Durability in withstanding voltage. The product may
be damaged if a voltage over this value is applied.
(The withstand voltage is not the supply voltage used to power the product.)
Z Zero-clear function This function to adjust the displayed pressure to zero.
