and cable dimension (1 mm^2). The tool automatically performs a new
calculation and verification.
6.2.7 Calculate Button
To describe the end of the loop, a unit “End segment” is entered – this
consists of the cable segment back to the loop driver only.
• Enter the cable length and cable resistance (in Ohm per km).
If illegal float values are typed or the float value is zero, a fault
warning will popup.
When pressing the Calculate Button, the tool automatically enters
values in the list box below and performs a new calculation and
verification. The calculation is for break after last loop unit.
