Instructions Remarks
06/97 3.00PREnn 06/97 Test versions
01/98 3.00 11/97-11/00 First serial version. Errors when empty spectrum recorded
with WAVE-STICK; automatic reset when signal is extremely
weak.
05/98 3.01 11/97-11/00 Elimination of errors in V. 3.00; improved application of empty
spectrum at tank bottom.
07/99 3.02 05/98-11/00 Implementation of the ModBus protocol; adaptation to
PROFIBUS interface; improved application of empty
spectrum at tank bottom; improvement of PC-CAT protocol
switching in multidrop operation; definition of 3.6 mA as lower
error current for the IS current output; improved tank bottom
tracing; improved spectrum evaluation at tank heights > 15
m.
11/99 3.03 05/98-11/00 Correction of a bug in the mode "Hold on Error" (output
current went to 1 mA or 3.6 mA; only V. 3.02); Adaption of the
HART protocol for operation with the program AMS, and
some smaller error corrections; Improved "tank bottom
recognition" (measured value now always goes to the
programmed tank bottom position); If no measured value is
found after start-up, the instrument goes directly into "tank
bottom recognition" and the local display to level = 0, if Fct.
3.2.5 Error Messages = NO is set.
