1. Correct the wiring.
2. Modify the wiring (bending
radius and stress).
Review the selected model.
Change the indication mode.
Install a 5μm filter to prevent
the intrusion and attachment of
the foreign matter. Also,
exhaust the filter periodically to
prevent drainage deposits.
Rework the assembly process
of the regulator.
If the regulator is tightened at a
torque over the specified range,
its mounting screw could break.
Also, remount the O-ring.
The figures in the display and
output drift when the power
supply is turned on. If fine
pressure needs to be detected,
wait approximate 20 to 30 min.
after turning on the power
supply to allow it to warm up.
