OPERATING INSTRUCTIONS
1 .
Introduction
This
section
of
the
manual
contains
information
regarding
the
correct
operation
of
the
Model
2000
DMM
.
It
is
recommended
that
the
contents
of
the
section
be
read
and
understood
before
attempting
to
operate
the
instrument
.
2 .
Shipping
Information
The
t~del
2000
was
packed
and
shipped
in
a
container
especially
designed
to
provide
adequate
protection.
Upon
receipt,
inspect
the
instrument
for
possible
shipping
damage
or
missing
parts
.
3.
Input
Power
Operating
power
for
the
standard
Model
2000
comes
from
four
non-rechargeable,
alkaline
(heavy
duty)
"C"
size
batteries.
This
power
source
typically
provides
25
hours
of
instrument
operation
.
Optionally
available
power
sources
include
rechargeable
Ni
Cad
batteries
and
an
AC
Po
w
er
Adapter.
To
use
these
po
w
er
sources,
the
meter
must
be
fitted
with
an
external
power
kit
.
The
instrunent
equipped
with
rechargeable
batteries
(4
"C"
cells)
will
typically
operate
for
15
hours;
recharging
,
using
the
AC
Power
Adapter,
takes
approximately
16
hours
.
If
the
batteries
measure
below
4 . 4V
under
load,
they
need
to
be
replaced
or
recharged.
Don't
leave
low
voltaoe
batteries
in
the
meter;
acid
corrosion
~ay
result
.
The
first
in-
dication
of
low
batteries
will
be
a
dim
display.
4.
ruse
Replacement
The
Model
2000
is
equipped
with
a
current
overload
fuse
to
pro-
tect
the
instrument
circuitry
from
inadvertent
applications
of
current
in
excess
of
2
amps
.
This
fuse
is
located
in
fuse
clips
on
the
main
P .
C.
board.
Replace
with
a 2
amp
AGC
or
AGX
fuse
by
removinq
the
four
screws
holding
the
case
halves
together
and
liftin9
off
the
ton
case
half
.
5.
Overrange
Indication
When
the
full
scale
capability
of
the
selected
range
for
any
function
is
exceeded
,
the
display
will
be
blank
.
The
overranqe
in-
dication
does
not
necessarily
mean
that
the
instrument
is
being
exposed
to
a
damaging
input
condition.
The
exact
overload
conditions
for
each
range
is
contained
in
the
specifications.

ASSEMBLY
TECHNIQUES
Before
the
assembly
process
is
begun,
verify
that
all
parts
are
present
by
examining
the
parts
bags
and
comparing
against
the
parts
list.
To
speed
the
assembly
process,
examine
and
familiarize
yourself
with
all
parts
in
the
kit
so
that
identification
will
be
readily
accomplished
.
When
capacitors
and
resistors
are
installed
in
the
board,
ensure
that
they
are
seated
flush
against
the
board.
Then
bend
out
the
leads
slightly
to
prevent
them
from
falling
out
when
soldering
.
After
soldering,
clip
off
any
excess
lead
lengths.
A
major
cause
of
kit
malfunctions
is
improper
soldering.
Another
is
improper
component
locations
. Be
sure
you
have
the
ri
ght
part
in
the
right
place
.
Pay
particular
attention
to
the
polarity
on
electrolytic
capacitors,
diodes
,
transistors
and
other
semi-
conductor
devices.
Apply
only
enough
heat
and
solder
to
make a
good
mechanical
and
electrical
bond
. Too much
solder
can
cause
solder
bridges
between
adjacent
foil
areas
on
the
P .
C.
Board.
You
will
notice
a
green
solder
mask
has
been
applied
to
the
board
to
minimize
this.
It
is
recommended
that
a 25
to
40-watt
soldering
iron
be
used
with
a
tip
small
enough
to
allow
easy
soldering
to
the
small
IC
pads
but
not
so
small
that
heat
is
not
retained
for
soldering
the
larger
parts
.
When
solder
is
applied
to
a
component,
be
sure
that
the
heat
is
simultaneously
applied
to
both
the
component
lead
and
the
component
pad
on
the
P.C.
Board
so
that
good
solder
flow
will
occur.
Be
sure
that
after
the
soldering
operation
is
complete
that
the
lead
still
extends
thru
the
solder
smoothly,
indicating
a
good
solder
joint
.
Do
not
ever
blob
the
solder
over
the
lead
because
this
can
result
in
a
cold
solder
joint
.
rJ!J--~
P.C
BOA
RO
BEND
LEADS
OUT
After
the
entire
P .
C.
Board
is
assembled,
and
prior
to
installing
the
board
in
the
case,
it
is
recommended
that
a
solvent
be
used
to
clean
the
flux
off
the
solder
side
of
the
printed
circuit
card.
This
will
prevent
any
dirt
from
accumulating
and
shortening
the
life
of
your
completed
instrument.
When
applying
solvent,
be
sure
that
you
hold
the
board
such
that
no
solvent
is
allowed
to
enter
the
IC
sockets,
trimpots
or
switch
assembly.
In
addition
to
the
parts
supplied
with
the
kit,
the
following
are
required
to
complete
assembly:
Resin
core
solder,
flux
remover
solvent
and
epoxy
glue
.

ASSEMBLY
PROCCDURE
It
is
required
that
the
Assembly
Procedure
be
performed
in
the
order
described
in
this
manual.
Before

is
started,
refer
to
the
Parts
List
and
verify
that
all
parts
listed
are
actually
present.
After
a
component
has
been
installed
and
soldered
in
place,
clip
off
any
excess
leads
from
the
solder
side.
