4.2.1 Force transducer replacement
If the force transducer breaks and needs to be replaced, follow this step-by-step replacement procedure carefully:
1.
Remove the pin from the transducer pin coming out of the transducer house.
2.
Disconnect the Tissue Bath from the Multi Interface.
3. Turn the Tissue Bath upside down and remove the transducer housing by loosening the two screws “A” and “B” as illustrated
in figure 4.2 below.
4.
The replacement transducer will be shipped with the new transducer inside a new transducer house.
5.
Place a small amount of vacuum grease (clear or whitish grease) around the bottom of the transducer housing to seal the
transducer housing when set back in place, see figure 4.3
6.
Carefully realign the transducer housing with the new transducer on the Tissue Bath and reinsert the Allen screws through
the bottom of the Tissue Bath.
7.
Tighten the screws and place some vacuum grease around the transducer pin that protrudes from the transducer housing,
see figure 4.3. Make sure that the hole is completely sealed to prevent buffer solution or water from entering the transducer
housing and damaging the new force transducer.
IMPORTANT NOTE
CALIBRATE THE NEW FORCE TRANSDUCER BEFORE PERFORMING A NEW EXPERIMENT.
