Pt1000

The 750-461/000-003 version calculates the resistance values of Pt1000 sensors
and outputs the data as temperature values. The temperature values are displayed
at a resolution of 1 digit per 0.1 °C in one word (16-bit). Temperature values
below 0 °C are represented in two's complement binary. As a result, 0 °C
corresponds to the numeric value 0x0000 and 100 °C to the numeric value
0x03E8 (dec. 1000). The possible numeric range corresponds to the defined
temperature range of -200 °C to +850 °C for Pt1000 sensors.
