APPENDIX A
REPLACING THE SENSOR MODULE
1 -
Always have the function switch in the
off
position with the adapter disconnected when
servicing the instrument or changing the sensor module.
2 - Remove instrument from the orange boot and then
remove the sensor module access cover.
3 - Locate the sensor module board. Care note its
location on the main board. It can be unplugged
by pulling it up.
4 - Select a replacement sensor module holding it
by the edges as shown to avoid static electricity
being transferred from your fingers to the
delicate semiconductor chips.
5 - Plug it into the main circuit board so that all the pins
on the main board fit into socket holes on the
module board. The replaced sensor module
should appear as in the photo for step 3.
6 – Replace the sensor module access cover.
7 – Replace the orange “boot.”
