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 instrument to the measuring conditions,
need to be entered. For models with a current output, the factory callibration for zero point and
span F is 4 mA and 20 mA, for digital outputs and the display module 0% and 100%.
A linearization, 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 part 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 Instrumen 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 32.
• 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 instrument 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 advisabel to leave the envelope curve mode after the mesauring 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 Instrument Functions" on the CD-ROM supplied.
