Recommendations on how to use the offset can then be supplied. Only a small
percentage of users have special working conditions or procedures that will benefit
from using the offset functionality.
In section 6.0 "Status" there are four sections:
-
6.1 "Sw ver.".
-
6.2 "Actual Pressure".
-
6.3 "Total Cycles".
-
6.4
"Last Service Date”.
In sub-
section 6.1, “Sw ver.”, the current software version of the PCI is shown
(For instance; 1.17 or 1.21 or 1.26).
In sub-section 6.2,
“Actual Pressure”, the pressure measuring accuracy of the PCI
can be checked.
When entering this menu point and connecting a pressure vessel (tire or air tank),
the PCI will show the actual air pressure of the vessel. With the + / - buttons it is
now possible to increase or decrease the air pressure in the vessel.
This way, the PCI 1200 accuracy (full range) can be compared with the measured
pressure of a reference pressure measurement instrument (Subsequent
verification).
Be aware of the accuracy of the reference pressure measurement instrument when
comparing the two pressure measurements.
In sub-section 6.3,
“Total Cycles”, the total number of completed filling sequences is
shown.
In sub-section 6.4,
“Last Service Date”, the number of completed filling sequences
since the last service is shown.
Calibration of PCI 1200:
Calibration is carried out at the factory before delivery. No recalibration is necessary.
All pressure values on the PCI are displayed relative to the current atmospheric pressure.
For instance: A wheel filled with 3.0 bar has a pressure of 3.0 bar above the current
atmospheric air pressure on the actual geographical location / geodetic height.
However for a more accurate measurement you have to take in account the deviation from
the e
xpected “zero”. This zero is at 1020 mbar at 20°C at sea level.
