Measured value display
During normal operation the measured value can be read at V0H0 In addition to this,
several other fields contain system information which might be needed, e.g., for
trouble-shooting. Table 4.1 summarizes the measured value displays.
4.7
Locking the parameter matrix
When all parameter entries have been made (see also Chapters 5
…
6) the matrix can be
locked by entering a code number.

The lock is released when a number between 670 and 679, e.g. 672, is
entered into the matrix at the same position.

Remarks
V0H0
Level or volume
Display in %, m, ft, hl, m
3
, ft
3
, t etc. according to
calibration and/or linearization.
The entries for the 0/4 mA and 20 mA value at V0H5
and V0H6 control the 10-step LCD bar diagram.
V0H8
Current measuring
frequency
Displays the frequency which is actually measured
by the probe. Can be used as a fault check (must
change as level changes)
V0H9
Measured value before
linearization
Indicates level in the units used for calibration or
before linearization
V9H0
Current error code
Error code of fault with highest priority appears on
fault condition, alarm LED lights or blinks
V9H1
Last error code
The previous (corrected) error code can be read and
deleted here - press »E« to delete
V9H3
Software version with
instrument code
The first two figures indicate the instrument, the last,
the software version; 33 = Version 3.3
