Notes:
1)
With cable length < 12 meters (see graphs page 4)
2)
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
3)
All ppm figures refer to full-scale which corresponds to a secondary current ( I
S
) output of 2 A.
