
10%.
Power saving
mode Check if the power saving mode is
selected.
Set functions.
Incorrect wiring
Check the wiring for the power supply.
Confirm that the brown and blue wires
are connected to DC(+) and DC(-)
respectively, and that the output line
has not come off (contact failure).
Correct the wiring.
Product failure Replace the product.

flashing.
Peak/bottom
indication
mode Check if the peak indication mode or
bottom indication mode has been
selected.
Release the peak/bottom
indication mode.
Wiring failure

the pressure
does not
satisfy the
specifications.
Intrusion of
foreign matter
Check for the intrusion and
attachment of foreign matter into the
pressure port.
Install a 5μm filter to prevent
the intrusion and attachment of
the foreign matter. Also,
exhaust the filter periodically to
prevent drainage deposits.
Air leakage
Check the air leakage from the
mounted part.
(Presence of the O-ring)
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.
Insufficient
warming-up
Confirm that the specified accuracy is
satisfied 20 min. after the power
supply is turned on.
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.
Product failure Replace the product.
