of this instrument.
Local wiring and safety regulations should be
strictly adhered to when installing this
instrument. If the installation methods and
cable types recommended in this guide are
followed, then the instrument will achieve the
levels of EMC protection as specied in the
appropriate manual.
Consult the serial label on the side of the
instrument for supply voltage requirements.

To protect the instrument setup
from unauthorised or accidental
tampering, a security access code
system is present. This is
implemented via the instrument’s
menu system which operates in two
modes, “locked” as indicated by a
padlock symbol and “unlocked” as
indicated by a key symbol.
