Tank height
function C.1.2.0
The height of the tank from the top of the tank process connection facing to the tank bottom. If not indicated
in the order, this is set at the factory to probe length.
Blocking distance
function C.1.9.0
Refer to section 7.1.2: Technical data, blocking distance for the minimum recommended value for a given
probe type. This prevents the device from displaying measurements within this distance to the flange and
avoids confusion with parasite signals near to the flange.
Reference offset
function C.1.10.0
Configure the device to measure the distance to the product surface using a reference point other than the
default flange facing.
Move the reference point above the flange facing by typing in a positive value. Move the reference point
below the flange facing by typing in a negative value.
Scaling the current output
The current output setup mode is used to create current output scales for the first and second (if ordered)
outputs that meet your requirements. You must define:
1. Output function
function C.3.1.0 (output 1-distance)
function C.4.1.0 (output 2-volume)
2. 4 mA setting
function C.3.2.0 (output 1)
function C.4.2.0 (output 2)
3. 20 mA setting
function C.3.3.0 (output 1)
function C.4.3.0 (output 2)
4 and 20 mA settings are defined in terms of distance from the flange facing or reference offset. These are
the minimum and maximum points of your measuring scale.
Using the optional second output, you can set up a separate scale for displaying another measurement
function (volume...)
Risk of measurement error!
In order to have the full current output range, do not set 4 mA setting within the device's blocking distance!
