• The remote zero-adjustment function forcibly displays the
pressure value at the time of application of an external
input signal to zero. Please select the remote zero-
adjustment function at the supplementary setting mode
when using this function.
• In the initial setting mode, if the output mode is set to the
forced output mode ( ), the comparative outputs are
forcibly maintained at OFF level in the sensing mode,
irrespective of Set Values P-1 to P-4.
Further, if the keys are operated as per the procedure
given below, the comparative outputs can be forcibly
switched either ON or OFF without applying pressure
at the pressure port. This is convenient for an operation
check of the comparative outputs or for an inspection
before commencing work.

• At the time of remote zero-adjustment input, the set
values are not corrected. When using the remote zero-

the set values do not exceed the rated pressure range.

PARTICULAR
USE
• Peak hold and bottom hold functions enable the display
of the peak value (maximum pressure value) and the
bottom value (minimum pressure value) of the varying
measured pressure.
These functions are convenient for finding the pressure
variation range or determining the reference for pressure
settings.

• Key-protect is a function which prevents any unintentional
change in the conditions which have been entered in each

Comparative Output 1 operates with the atmospheric pressure as the reference.
• Maintain the pressure at a constant level for at least 2 ms after the
remote zero-adjustment input is made Low (High in case of PNP output
type). If used in a transient state, it will result in wrong operation.
• Use the comparative outputs at least “set response time
+ 2 ms” after the remote zero-adjustment input is made Low (High in
case of PNP output type).
• At the time of remote zero-adjustment input,
is displayed on the
3 1/2 digit display for 1 sec. approx.
• If the power supply is switched off and then on again, the remote zero-
adjustment input value (set Value P-A) is cleared and the sensor returns
to normal operation with atmospheric pressure as the reference.
