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].
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.
Variation in repeated measurement of pressure display or ON-OFF output
point when the pressure changes at 25 centigrade.
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.
Refer to "Display resolution".
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 36.)
A type of chattering.
The pressure range that can be set for switch output.
A stainless steel pressure-detecting part of the pressure-detecting element. It
is suitable for measuring fluid such as water.
Sometimes referred to as "ON-OFF output".
TSJ is an abbreviation for Tube Swage Joint. As a fitting, a Swagelock fitting
is recommended.
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.
URS is an abbreviation for Union Ring Joint. As a fitting, the Swagelock VCR
fitting is recommended.
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 36.)
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.)
This function to adjust the displayed pressure to zero.
