Once all the desired pressure points have been accepted the
adjustment will be performed. The message “COMPLETED” will
then be displayed. Press the
key to finish and return to the
‘Cal menu’.
For absolute units, the following default pressure values
will be chosen for a 2 point calibration:
1 current reading
2 full-scale
For a 3 point calibration, the following default pressure values will
the chosen:
1 current reading
2 midpoint between 1st point and full-scale
3 full-scale
For the first point, you will be presented with the following screen:
The current pressure value is displayed on the upper line. Once you
have set up the desired pressure point and the pressure is stable,
press the
key and you will see the following screen:
This displays the last pressure reading (from the previous screen) on
the top line and on the second line you can set the corrected value.
Set the required value and press the key.
Select ‘Yes’ or ‘No’ at the next screen and press the key.
The procedure for the remainder of the pressure points on an
absolute transducer is identical to that for a gauge transducer.
For both gauge and absolute transducers, the pressure point values
are limited as follows:
Gauge transducers, all points:
>= -1 bar (-15 psi) and < 105% full-scale pressure
Absolute transducers, all points:
>= 0 bar (0 psi) and < 105% full-scale pressure
Additionally, pressure points must lie in the following order:
Point 3 > Point 2 > Point 1
Absolute:
Point: Pressure value:
Point: Pressure value:
Pressure point limitations:
Notes : If at any time during the procedure you wish to exit and
return to the ‘Cal menu’ then press the key.
The message: 'Sure ? No Yes' appears. Select 'Yes' to exit or 'No'
to continue with the zero/span calibration.
