Readings in % refer to the measuring span
For a correct determination of the overall measuring error, both sensor and transmitter
measuring deviations have to be considered.
1) The temperature transmitter should therefore be protected from temperatures over 85 °C (185 °F).
2) For measuring spans smaller than 50 K additional 0.1 K
3) ±0.2 % for measuring ranges with a lower limit less than 0 °C
4) Use resistance thermometers with shielded cable, and ground the shield on at least one end of the lead, if the
cables are longer than 30 m or leave the building.

The lower limit of the measuring range is congurable between
-50 ...+150 °C.
The possible upper limit of the measuring range is dependent on
the respective lower limit of the measuring range. For possible
combinations of lower and upper limits of the measuring range, see
diagram. For clarity, this dependency has been shown in 50 °C steps
in the examples in this diagram. The conguration software checks
the required measuring range and will only accept permissible values.
Intermediate values are congurable; the smallest increment is 0.1 °C.
The thermometers are delivered with a basic conguration (0 ... 150 °C,
downscale) or congured to customer specications within the
congurable limits.
With conguration to customer specications, the measuring range
will be shown clearly on the instrument label. The conguration and
the choice of parameters is described in the menu-driven conguration
software. Changes to the conguration 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
