Update Processor or
Scale Software
CAUTION
OBSERVE PRECAUTIONS FOR HANDLING
ELECTROSTATIC SENSITIVE DEVICES.
On most models of the PS scale, the processor on the main PCB board is attached
through a socket that allows software updates or processor upgrades to the PCB.
1. Record the set up data of the scale. See chapter 4
2. Remove power from the scale and remove platter
3. Make sure you are statically grounded with appropriate wrist wire or other means.
4. Remove PCB cover. Note, the scale connectors are attached to the PCB.
a. PS15 : Turn scale over, remove bolt, push on sides of plastic cover to
release the cover tabs from the base slots.
b. PS60, 6L, 30 & 3L: On the top of the scale, unscrew the bolt that holds
the PCB cover to the scale. Lift off cover.
c. PS90: Unloosen the two screws holding the connector/PCB cover to the
scale base. PCB board is attached to the cover.
5. Locate socket (red circle on PCB photo above) and processor (Black IC chip with
white label) on PCB board.
6. Pull processor out of the socket by the use of an IC chip extractor tool (MT Part
Number 14608000A or equivalent). Insert extraction tool under the processor at
one of the corners and pull up.
7. Position new processor above the PCB socket so the beveled corner of the
processor is lined up with the bevel corner of the socket. Carefully press processor
into socket.
8. Install PCB cover, and power up scale. Since there is no set up or calibration
information on the new processor, an Error 3 code may appear. Press UNITS key
and hold to access Setup mode. Enter required set up data and calibrate the scale
per Chap 4.
Note: If there is NO SOCKET
on the PCB board, than the
processor is soldered
directly to the PCB and can
not be removed. Replace the
PCB board and matching
processor.
Note: Beveled corner of the
socket is at the upper -left
location. Processor is the
black IC chip with the white
label.
