Tech Note 18 Detail

Constant output using external power supply.

Affected Products:

CI-6511 NOT A VALID PART NUMBER

Problem/Symptom:
The output of the CI-6511 Force Transducer is a constant value when powered by an external source (i.e. not a battery). It does not change with force.

PASCO Solution:
The power supply for this unit must have a floating ground, rather than an Earth ground. (The SF-9584 power supply will not work, for example.) Use a battery to test the force sensor; if it works okay with the battery it is likely that the external source does not have a floating ground.
