Diagram for measuring range
With configuration to customer specifications, the measuring range will be shown clearly
on the instrument label. The configuration and the choice of parameters is described in the
menu-driven configuration software. Changes to the configuration must be noted on the
label using a water-resistant felt-tip pen.
Possible combinations of the lower and upper limits of the measuring range
The upper limit of the measuring range is dependent on the respective lower limit of the
measuring range.
For clarity, this dependency has been shown in 50 °C steps in the examples in these
diagrams. The configuration software checks the required measuring range and will only
accept permissible values. Intermediate values are configurable; the smallest increment is
0.1 °C.

Please note:
The measuring range of the thermometer is limited by the application range of the
measuring element, not by the adjustable range of the transmitter.
