CURRENT SIMULATION (4-20 mA)
The transmitter can simulate an output between 4-20 mA.
Using five predefined steps or a free selectable value between 3,80 mA
to 20,8 mA (Transmitters with HART® Protocol 3,90 mA to 20,8 mA)
5.
Navigate to program point
1.10 – CURR SIMU
, and push the navigation button to enter the
menu.
6.
Two choices appear on the screen: “
Set
” and “
Free
”
7.
Choosing
Set
allows a value to be set in five steps: 4, 8, 12, 16, 20 mA
By default the current simulation is
Not active,
as shown in the display
Choose one of the five steps, and push to confirm
The status on the display will change to
Active
and the current simulation is started for
the selected step.
Push the navigation button to de-activate the current simulation.
Move the navigation button to the left to go back and leave this menu.
8.
With the option
Free
, a current between 4 and 20 mA can be configured.
By default the current simulation is
Not active,
as shown in the display.
Enter the desired value, and push to confirm.
The status on the display will change to
Active
and the current simulation is started for
the selected value.
Push the navigation button to de-activate the current simulation.
Move the navigation button to the left to go back and leave this menu.

TANK LINEARIZATION
In this menu, various tank linearization’s can be selected.
Factory setting = No linearization
For a horizontal tank or a tank with a cone, linearization can be configured. The volume as
a measured value will be displayed on the home screen. (Must be set in
1.04)
The values (configured in the following settings) must be in meters.
1.
Navigate to program point
1.11 – TANK LIN,
and push the navigation button to enter the
menu. Six choices appear on the screen:
No Lin
= No linearization
Hor. Tank
= Linearization setting for a horizontal tank: cylindrical and elliptic
Vert. Cone
= Linearization setting for a vertical tank with a conical bottom.
Vert. Sphere
= Linearization setting for a vertical tank with a
spherical bottom.
Vert. Trunc
= Linearization setting for a vertical tank with a
truncated bottom
.
Free lin
= Free linearization setting, adjustable in 70 free programmable points.
The following describes the setting for each linearization configuration.
LINEARIZATION DISABLE
With the choice
No. Lin
. an existing linearization can be turned off and can be identified by the
symbol on the home screen:
Linearization can be recognized by the following symbol on the home screen:

Select
No Lin.
and confirm this with the button.
For measuring weight (Kg and Tons), a reliable accuracy cannot be guaranteed, the SDT43 cannot compensate for
Specific Gravity changes or any thermal increase or decrease.
