Operation
NULL (zero) point suppression (Conductivity)
NOTICE!
The transmitter LMIT09 DPV1 has been designed in such a way that the
start and end values of the measuring range are assigned to the current
output signal 4(0)...20 mA in the default setting.
It is also possible to set up an optimised range span and implement zero-
point suppression according to the measuring task. This may for example
be required if it is necessary to record minor changes in measuring signals
with a high resolution. In addition to selecting the current output range
0...20 mA or 4...20 mA (see
of the measuring range (NULL) and the end of the measuring range (SPAN)
can be freely selected within the defined limits.
