Investigation method Countermeasure
Install a 5 µm filter to prevent
foreign matter from entering
the pressure port. Also, clean
the filter regularly to prevent
drainage deposits.
Rework the piping.
If an excessive tightening
torque is applied, the
mounting bracket, screws or
the product may be damaged.
After energizing, the display and
output can drift. For detecting
fine pressures, warm up the
product for 10 to 15 minutes.
Replace the product.
"M" in the part number means
that the units cannot be
changed.
(kPa↔MPa can be selected)
∗: The units selection function is
not available in Japan due to a
new measurement law.
∗: It is fixed to the SI unit "kPa",
"MPa".
Replace the product.
Replace the product.
Mount the product on the
panel correctly.
Replace the product.
Rework the piping.
If an excessive tightening
torque is applied, the
mounting bracket, screws or
the product may be damaged.
Replace the product.
(1) Check the pressure
setting.
(2) Reset the function
settings.
(1) Correct the wiring
(2) Correct the wiring
conditions (reduce the
tensile force and increase
the bending radius).
Replace the product.
