7. Configuration of models TR30-W and TR31-W
Screenshot from the configuration software
The lower limit of the measuring range is configurable 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 configuration software checks the required measuring range
and will only accept permissible values. Intermediate values are configurable; the smallest
increment is 0.1 °C. The thermometers are delivered with a basic configuration (0 ... +150 °C,
downscale) or configured to customer specifications within the configurable limits.
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.
