9.6. Replacing a CM-2 Sensor Unit
Note:
The LabSwift-aw contains susceptible electronic assemblies. Please pay
attention to protect these items from discharge. You can achieve this by
discharging yourself at a grounded, conductive surface (e.g. radiator) before
you open the housing of the instrument.
• Switch off the instrument and disconnect the mains from the system.
• Open the instrument cover and remove the 4 screws of the cover plate.
• The housing cover can be set or inclined aside carefully
• The cover plate is still connected to the housing cover by a ribbon cable.
Do not unfix it!
• Afterwards you can unplug the connecting PCB. Therfore hold the PCB at
the long side and lift it carefully.
• Remove now the two screws, which fix the actual sensor in the measuring
head and lift the sensor unit completely out of the head.
Tip:
Exchange at the same time the white sinter filter in front of the sensor. Press
the sinter filter downwards and insert a new one.
• Insert now the new purchased measuring sensor in the same place and fix
it with the screws.
Warning !
- Never press with fingers or any other item on the top of the measuring cell,
this might damage the sensor protection filter and leads to the damage of
the sensor
- Always remove the measuring sensor during the exchange of the sinter
filter. Otherwise there may be the risk that the sensor get dampaged
during the removal or mounting of the filter.
Every measuring sensor is protected with a password. The factory-setting is
„8808“. Do not forget to adjust the password according to your requirements,
otherwise the protection can’t be assured.
