CALmRATION
The
controller
was
carefully
calibrated
during
manufac
turing
and
should
not
require
recalibration
Most
calibra
tion
errors
are
caused
by
improper
leveling
The
controller
should
be
level
when
the
pointer
on
the
leveling
indicator
is
directly
over
the
index
mark
Fig
11
In
some
cases
the
leveling
indicator
may
not
be
accurate
enough
The
pointer
may
be
over
the
index
mark
but
the
controller
still
may
not
be
operating
within
the
tolerance
of
its
scale
setting
In
this
case
carefully
bend
the
steam
trap
siphon
loop
until
the
controller
switches
properly
