601-12.
Noise
rejection can
be
selected for 50 Hz
or
60
Hz
line
frequencies.
The
line
frequency, as
set at
the
factory,
is
indicated
on a
decal
attached
to the bottom
of
your
Multimeter.
Refer to
the
Line

THEORY
OF
OPERATION
601-14.
The
theory
of
operation
of
the Multimeter is
illustrated
by
the
Main
PCB
Assembly
schematic in
Section
7.
The
battery
power
supply
is
shown
above
the
standard
power
supply
on
the
schematic. The
Multimeter
can
be
used
with
line
voltage
from
90V to 264V,
50
Hz or
60
Hz
(To
select
the
proper
line
voltage
configuration,
refer
to
the
AC
Line
Voltage
procedure,
given later in
this
subsection.)
Fuse F3
provides
protection for
the
power
supply.
Line
power
input
is
rectified,
filtered, and
regulated.
The
output
of
the
power
supply
acts
as a
current
source
for
the
battery.
The
battery
determines
the
voltage
level
into
the
power
converter. Do
not
operate
your
Multimeter
with
the
battery
removed.
The
power
converter
uses
the
flyback
transformer
technique
to
develop
several
output
voltages
so
that +1
1.5,
-11.5,
+2.9
and
-6.5V
(with
respect
to
power
supply
common)
are
available.
