Info:
Instrument type and serial number
In this menu item, the adjustment units of the instrument are deter-
mined. The selection determines the unit displayed in the menu items
"
Min. adjustment (Zero)
" and "
Max. adjustment (Span)
".
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.
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.
The installation position of the instrument can shift the measured
value (offset). The position correction compensates this offset. By do-
ing so, the actual measured value is taken over automatically.
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.
Save your settings with
[OK]
and move with
[ESC]
and
[->]
to the
next menu item.
After the position correction is carried out, the actual measured value
is corrected to 0. The corrective value appears with an inverse sign as
offset value in the display.
The position correction can be repeated as often as necessary. How-
ever, if the sum of the corrective values exceeds 20 % of the nominal
measuring range, then no position correction is possible.
During adjustment, the pressure is entered e.g. for the level with full
and empty vessel, see following example:
Basic adjustment - Ad-
justment unit
Basic adjustment - Posi-
tion correction
