After this, there are 69 more
linearization points available.
When all (needed) points are filled in,
the linearization must be saved. Push
the navigation button to the left and
select SAVE to save this linearization.
The figure above shows a tank with standard dimensions. Free linearization can applied on a
wide variety of tanks with non-standard dimensions.
Save:
When all desired measurements are completed and all parameters have been set, the
linearization must be saved. Push the navigation button to the left to Exit and select
to save the linearization. The transmitter will return to the main menu.
WARNING AND PRECAUTIONS
When a tank filling (
Xn
) is not configured till 100 %, the transmitter will calculate the
remaining part. This calculating method is linear and will only be used for the remaining part
up to 100 %.
It is not advisable to manually adjust the SPAN in program point 1.02 after a linearization has
been configured. If the SPAN is adjusted after a linearization configuration, a warning will
appear on the screen when entering 1.02.
When the a free linearization is used for measuring weight (Kg and Tons), a reliable accuracy
cannot be guaranteed due to external influences such as heat and tank wall expansion.
The
change of Specific Gravity due to different temperatures cannot be compensated by the
SDT43 pressure transmitter.
SIMULATION
After linearization is entered and stored, it is possible to perform a simulation. (Based on the
stored linearization) The transmitter will convert the entered mWc to hectoliters.

BURST MODE
The transmitter (Only when HART® is present) can be configured for Burst
mode. This will enable continuously broadcasting standard HART® reply
messages.
