13 . Ambient Pressure Compensation
Open the applied pressure to the surrounding air so that it equals the
ambient pressure and press the button for 3 seconds or more
while the current value or reference value is being displayed.
The ambient pressure point will be corrected.
*1 Ambient pressure can be corrected within a range of ±5 % of F.S.
When atmospheric pressure compensation has been performed, the
settings will be saved even when power to the sensor is turned off.
*2 AP-C31/C31P/C33/C33P: Can be used during focus mode operation
as well. Values will be compensated based on the center pressure.
14 . Key Lock
Disables operations that would modify the sensor’s configuration. Display
content can be toggled.
Pressing and holding either or for at least 3 seconds while pressing
button will lock the keypad and cause the display to flash.
* The same key combination will deactivate the key lock feature.
11 . Default Mode Settings (Initialization)

15 . Error Displays and Corrective Actions
■
Error displays during normal operation
• No difference in sensitivity
(during 2 point tuning/active
tuning).
• There is an applied pressure
of 5 % of F.S. during ambient
pressure compensation.
• An excess current is flowing to the
control output.
• Reading is falling below
(exceeding) configuration/display
pressure range.
• Reading is exceeding (falling
below) configuration/display
pressure range.
• When there were not at least 2
shift inputs during active 2 point
tuning.
Adjust the air pressure device so that
there will be a difference in sensitivity.
(Return to atmospheric pressure.)
Repeat atmospheric compensation.
Check the load and return it to the
rated range.
Return the pressure to the rated
pressure range.
Return the pressure to the rated
pressure range.
Repeat the active tuning procedure so
that there are at least 2 shift inputs.
