6. Commissioning, operation
Medium temperature outside the span
■
If the media temperature configured in the transmitter exceeds
the span, the transmitter will operate in a linear fashion within the
following limits: 3.8 mA (MRS); 20.5 mA (MRE). If these limits are
exceeded, then an error will be signalled.
Hysteresis on return to the measuring span
■
After the linear error limits have been exceeded, on return to the
measuring span, a hysteresis of 0.1 mA must be passed. This
hysteresis prevents the transmitter from jumping back and forth
between error and measuring mode.
