5.2.2 Measuring range
The known measuring ranges for the passive sensing elements are preset:
Passive temperature signals Preset measuring range
LG-Ni1000 50… 250 °C
2x LG-Ni1000 or T1 50... 150 °C
Pt1000 50...+400 °C
The measuring range must be entered as per manufacturer information or the
required allocation for active signals. To do this, enter the lower (Value low) and
upper (Value high) measured value.

Setting values
Operating line Range Factory setting
Value low Depending on selected type Type-dependent
Value high Depending on selected type Type-dependent
Room temperature with active signal DC 0...10 V = 0...50 °C:
Example
Lower measured value (Value low): 0 °C
Upper measured value (Value high): 50 °C
A 5 V signal results in: 25 °C
5.2.3 Measured value correction
With passive temperature sensors, the measured value can be readjusted by 3.0
to 3.0 K to compensate for line resistance. You can thus on-site calibrate using a
reference instrument.
