Measuring compliance of passive radiator

I am using a handheld force meter and caliper to measure compliance of passive radiators. The force meter is clamped to the caliper. Caliper is used to show the panel displacement whereas force meter displays the corresponding force. I can then obtain compliance C mm/N. I am planning to use an Arduino controlled Z-axis for automatic measurement. The force meter has a USB interface for data acquisition.

I should be able to measure BL vs displacement of a driver by adding a programmable DC supply.
