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 signalling and measuring mode.

6. Configuration
Configuration is carried out using a USB interface with a PC via the
model PU-548 programming unit (accessories, order number: 14231581).
The connection with the thermometer is made via the appropriate adapter
cable (accessories: DIN connector, order number: 14005324).
Measuring range, dampening, error signalling, Tag no. and other
parameters can be adjusted (see configuration software).
