Notes:
1)
Programmed in the range 125 to 2000 A with a resolution of 125 A;
this is done by using a programming plug (see page 10)
2)
Depending on programming plug
3)
Single pulse of 100 ms only, not AC. The transducer may require a few seconds to return to
normal operation when autoreset system is running.
4)
All ppm figures refer to full-scale which corresponds to a secondary current ( I
S
) output of 2 A.
