The indicator has a SO+ SO- pulse output. This allows you to con-
nect another pulse device (SO) that reads impulses generated
by the meter.
No additional device is required for the correct operation of the
meter.
The meter has the option of sealing the input and output termi-
nals, preventing the meter from being bypassed.
The meter is marked with an individual factory number to enable
its unambiguous identification. The marking is indelible (laser
engraving).
