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 the 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 %.
Alinearization function with max. 32 points, which is bades 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 with 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 Instrument Functios" on the CD-ROM supplied.
Comply with the following instructions when configuring the functions in the "basic setup" (00):
• Select the functions as descriped on → ä 27.
• Certain functions (e.g. starting interference echo suppression (053)) prompt you to vonfirm 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 return 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 advisable to leave the envelope curve mode after the measuring point has
been optimized.
• It he power supply fails, all preset and confured 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.
