Conditions for safe measuring
mode - device configuration
with increased security during
parameter entry With the "Increased security during parameter entry" method, the device checks whether a number of
operating steps have been performed beforehand and whether certain parameters have been configured with
reliable settings. This method of configuration is no longer possible if one of these operating steps has been
performed or if the configuration is not permitted. A corresponding message is displayed.
The "Increased security during parameter entry" method is no longer possible after the following operating
steps.
– Position adjustment performed or measuring range set on site without using the on-site display.
– Following a download
– After a configuration backup using HistoROM
®
/M-DAT
– After a reset apart from after the reset code "7864"
– After performing sensor recalibration (observe Note

ä
15).
– Following current trimming
– For the LEVEL SELECTION parameter, the "Level Easy Height" or "Level Standard" option was selected
(permitted setting for LEVEL SELECTION is "Level Easy Pressure").
The reset code "7864" resets all the parameters to their delivery status.
After this, the "Increased security during parameter entry" method is possible once more.
Permitted parameter setting:
Only certain settings are possible for some parameters. If a setting that is not permitted has been selected for
one of these parameters, the "Increased security during parameter entry" method is not possible. This method
is possible once more as soon as the permitted setting is selected for the parameter.
