3200B SERIES OPERATION MANUAL

Installation & Power Requirements for the 3200B
It is necessary that for correct operation the Phase (Live) and Phase (Neutral)
MUST be connected correctly (some plugs used in non-UK countries can be
connected either way round, therefore this check will be necessary). There should
only be a small voltage between Phase (Neutral) and Phase (Earth).
To keep the LOOP impedance value to a minimum, the mains input to the 3200B is
hardwired to the instrument. This avoids any introduction of unnecessary
impedance. It is desirable that the 3200B is connected to a supply point with low
LOOP impedance as this will limit the lowest value available LOOP impedance from
the 3200B using as good a quality outlet (contact wise) as possible.
