A testing device characterizes a damper/valve in situ in a HVAC system. It comprises a controller including a processor and a memory and circuitry. The testing device is mounted on a damper assembly having a control shaft and a damper rotatably coupled to the control shaft such that the control shaft is activated by the circuitry of the testing device. The testing device further comprises computer-readable logic code to: open and close the damper by actuating the control shaft, detect a rotational position of the damper and a torque required to move the damper to the rotational position, characterize a plurality of torques required to drive the damper to a plurality of pre-determined rotational positions of the damper when subjected to a fluid flow to generate damper rotational position data vs. torque data, and store the damper rotational position data vs. torque data to produce damper characteristic graphs.
