The Levelflex is precalibrated at the factory to the probe length ordered so that in most cases only
the application parameters, which automatically adapt the device to the measuring conditions, need
to be entered. For models with a current output, the factory calibration for zero point and span F is
4 mA and 20 mA, for digital outputs and the display module 0 % and 100 %.
A linearization function with max. 32 points, which is based on a table input manually or semi-
automatically, can be activated onsite or via remote operation. This function allows the conversion
of the level into units of volume or weight, for example.
Note!
The Levelflex M also makes it possible to monitor the probe for breakage. On delivery, this function
is switched since any probe shortening would be mistaken for a broken probe. To activate this
function, perform the following:
1. With the probe uncovered, perform a mapping ("range of mapping" (052) and "start
mapping." (053)).
2. Activate the "broken probe det" (019) function in the "safety settings" (01) function
group.
Complex measuring operations necessitate additional functions that the user can use to customize
the Levelflex as necessary to suit his specific requirements. The functions available to do this are
described in detail in BA245F – "Description of Device Functions" on the CD-ROM supplied.
Comply with the following instructions when configuring the functions in the "basic setup" (00):
• Select the functions as described on → ä 31.
• Certain functions (e.g. starting interference echo suppression (053)) prompt you to confirm this
function after entering the data. Press
function is now started.
• If you do not press a key during a configurable time period (→ function group "display (09)"),
the system returns automatically to the measured value display position.
Note!
• The device continues to measure while data entry is in progress, i.e. the current measured values
are output via the signal outputs in the normal way.
• If the envelope curve mode is active on the display, the measured values are updated in a slower
cycle time. Thus, it is advisable to leave the envelope curve mode after the measuring point has
been optimized.
• If the power supply fails, all preset and configured values remain safely stored in the EEPROM.
Caution!
All functions are described in detail, as is the overview of the operating menu itself, in BA245F –
"Description of Device Functions" on the CD-ROM supplied.
