CALIBRATION
Introduction
The MicroLab!
is
primarily a
digital
instrument, and
therefore
requires
little
calibration. The
power
supply
is
the
only
element
of
the
MicroLab!
that needs
occasional
calibration.
In
this section,
you'll find
instructions
on
disassembling the
MicroLab
|,
and
calibrating
the
power
supply.

Before
you
begin to take
apart the

|,
unplug
the
power cord
and
any
other
cabling,
and
remove any
personality cards
that
are
plugged
into
the chassis.
1.
Close the
clear
plastic cover
and turn the
MicroLab
over
on
its
top,
as
shown
in

Remove
the
six
screws
shown
in

with
a
long-

3.
Carefully hold
the
top
and
bottom
parts
of
the
MicroLab
|
together, and turn the
MicroLab
|
back
onto
its
base.
4.
Slowly
lift
the
top
of
the
MicroLab
|;
be careful to move
the
top
so
that
it
clears the personality card
guide
rails.
As
the
top
of
the cabinet clears the
Main
Interconnect
circuit
board,
rotate
the
top to
the
right, exposing
two
cables that connect the
Keypad/

and the
Main
Interconnect
board.
