Unit of measurement:
If the level should be adjusted in a height unit, the density of the me-
dium must also be entered later during the adjustment.
In addition, the temperature unit of the instrument is specified. The se-
lection determines the displayed unit in the menu items "Peak value,
measuring cell temperature", "Peak value, electronics temperature"
as well as "HART variables".
Temperature unit:
Enter the requested parameters via the appropriate keys, save your
settings with [OK] and jump to the next menu item with the [ESC] and
the [->] key.
In this menu item, you select the unit of the Secondary Value (SV2).
It can be selected from the distance units such as for example m, mm
and ft.
Especially with chemical seal systems, the installation position of the
instrument can shift (offset) the measured value. Position correction
compensates this offset. In the process, the actual measured value
is taken over automatically. With relative pressure measuring cells a
manual offset can also be carried out.
If the actual measured value should be taken over as correction value
during automatic position correction, this value must not be influ-
enced by product coverage or static pressure.
With the manual position correction, the offset value can be deter-
mined by the user. Select for this purpose the function "Edit" and
enter the requested value.
