PARAMETERS
7.4.68
Cable length, single distance
This parameter is used to set the one-way cable length between sensor and device input.
Option
1.0 … 10.0 … 100.0 m
Prerequisites for visibility
– Parameter
Option
Temperature sensor
– Parameter
Option
Via cable length
• The parameter is in the parameter window
.
7.4.69
Cable error compensation
This parameter is used to define how cable errors that occur are compensated.
Note
Cable error compensation based on the cable length is possible only for cables with copper conduc-
tors.
Option
None
Cable error compensation is not used.
Via cable length
The following dependent parameters are shown:
•
•
Cross-section of conductor, value* 0.01 mm²
Via cable resistance
The following dependent parameters are shown:
•
Cable resistance (total of fwd and rtn conductor)
Prerequisites for visibility
\ Option
Temperature

• The parameter is in the parameter window
.
7.4.70
Cable resistance (total of fwd and rtn conductor)
This parameter is used to set the cable resistance of the temperature sensor connected.
Note
To measure the cable resistance correctly, the conductors must be shorted together at the cable end
and must not be connected to the input.
