Service Code
(dec) (hex)
Service
Name/
Access Rule Description of Service
53 0x32 U-Coarse
Zero
Adjustment
Sends a Target pressure value, usually zero, to the device. Corrections
to the digital zero are made to bring the pressure Value (Attribute 0x6)
to the specified Target Value. The range of this service is –4 to +20%
of Full Scale. This service is also initiated by depressing the Coarse
Zero Push Button for at least 2 seconds.
75 0x4B U-Fine Zero
Adjust
Sends a Target pressure value, usually zero, to the device. The value of
Offset-B (Attribute 0x10) is modified to bring the pressure Value
(Attribute 0x6) to the specified Target Value. The range of this service
is ±2% of Full Scale.
76 0x4C U-Gain
Adjust
Sends a Target pressure value to the device. The value of the Gain
(Attribute 0x0E) is then modified to bring the pressure Value
(Attribute 0x6) to the specified Target Value. Valid gain values range
from 0.98 to 1.02.
