Parameters
—
7.13.1.4.3 Dependent Parameter
Cable error compensation
Options:
• Via cable length: Cable error is compensated by entering the cable length.
This method may only be used for copper cables.
• Via cable resistance: Cable error is compensated by entering the cable resistance value.
—
7.13.1.4.3.1 Dependent Parameter
Cable length, one-way distance
01.0...10.0...100.0
Sets the one-way cable length of the connected temperature sensor.
The maximum cable length permitted between the sensor and device input is 100 m.
—
7.13.1.4.3.2 Dependent Parameter
Cross-section of conductor, Value* 0.01 mm²
Options:
The 150 option corresponds to a cross-section of 1.5 mm
The cross-section of the conductor to which the temperature sensor is connected is entered using
this parameter.
—
7.13.1.4.3.3 Dependent Parameter
Cable resistance in milliohms [total of forw. and ret. conduct.]
Options:
This parameter sets the cable resistance level of the connected temperature sensor.
To measure the cable resistance correctly, the conductors must be shorted together at the end of
the cable and should not be connected to the analog input.
