1. A force measurement device comprising:
a jack having:
a piston, configured to engage an object to be lifted or pushed;
a housing, wherein the housing includes a high pressure chamber configured to receive at least a portion of the piston, wherein altering a pressure within the high pressure chamber can actuate the piston to move further into or out of the housing;
a release valve in fluid communication with the high pressure chamber and configured to release pressure within the high pressure chamber; and
a force gauge attached to the housing and configured to measure a force applied to the piston by the object to be lifted or pushed;
wherein the force gauge and the release valve utilize the same fluid connections to the high pressure chamber.
