6.4.5 Distance measurement
The instrument displays distance measurements when an output is set to distance. Menu items
related to distance measurement are:
•
output function (C.3.1 or C.4.1)
•
tank height (C.1.2)
•
blocking distance (C.1.9)
•
detection delay
Use the flange facing as the reference point for the 4 and 20 mA current output settings. The 4
and 20 mA current output settings are the minimum and maximum points of the measurement
scale. You can change the reference point from which distance is measured. Use this menu
item:
•
reference offset (C.1.10)
NOTE!
If you move the reference point above the flange, add this value when give a distance for the 4
and 20 mA current output settings. If you move the reference point below the flange, subtract
this value when you give a distance value for the 4 and 20 mA current output settings.
CAUTION!
If the distance for the 4 mA is set in the blocking distance, the instrument will not be able to use
the full current output range.
