6
IC Installation Procedure
This section describes the procedure you can use to install ICs. It includes
instructions for the disassembly of the medTester 5000, replacement and
installation of ICs, testing of your IC installation, and reassembly.
Note
This is your authorization to remove the Quality seal and to open the
instrument case to install legitimately purchased upgrades and
modules.
DANGER—UNPLUG THE INSTRUMENT POWER CORD!
Service should only be performed by qualified personnel. There are
dangerous voltages present inside this instrument. Always unplug the
power cord before opening the case. Never plug in the power cord
while the case is open.
Disassembly
Disassembly involves opening the medTester case in order to access ICs. To
disassemble:
1. Peel off the Quality seal sticker that seals the case halves together.
Discard it.
2. Remove the nine (9) screws and lockwashers holding the top case to
the bottom case. There are four (4) on top, two (2) in the front, and
three (3) in the back.
3. Pull the case halves apart. Pull the top half forward while turning it
upside down and lay it down. There are cables connecting the two
halves together. Take notice of these—if they come apart, you will
know how to put them back together.
4. Remove the six (6) screws holding the metal shield to the digital PCB
(printed circuit board).
