Testing the Equivalence Principle on Earth and in space

Calibration of read out capacitance bridges performed by applying a relative displacement of test cylinders of known amount (with micrometric screw)

Calibration factors (Feb-June 2001) of bridges in X and Y sensitive axes:

X 1 Volt= 29.87 mm

Y 1 Volt=30.46 mm
