Signal Range

The output signal is divided into defined ranges (Figure 17, p. 95).
The transmitter converts the measured pressure into an output current which is nor-
mally in the range from 4 mA (start of scale) to 20 mA (full scale).
On exceeding the measuring limits, measured values are displayed correctly in the
underflow or overflow range. The message "UNDER" or "OVER" appears alternately
with the selected unit in place of the bargraph. The possible overflow range can be
adjusted through HART®. If the overflow or underflow range is exceeded, the output
current remains constant.

ital transmitters with analog output signal" of 18.01.94.
NOTE
The setting of the overflow range and the fault current range is freely selectable.
Useful setting possibilities are shown in Figure 17, p. 95.
