When installing an electrophotographic printing machine, the printing machine is mounted on a mobility plate, if the force required to move the printing machine exceeds 50 pounds. In order to determine whether a mobility plate is required, a gauge is employed which measures the softness of the floor covering. The gauge has a dial indicator, plunger and housing. It utilizes an applied force to measure the carpet deflection. The housing rests on four points. The measurement plunger is adjusted to the same plane as the four points and attached to the dial indicator. As a downward force is applied, the four points are driven into the carpet and the measurement plunger continues to rest on top of the carpet. The resultant reading is the distance that the four points were pressed into the carpet. With a knowledge of the force required to move the printing machine when on a variety of carpets, and knowing the deflection readings for these carpets, one may readily determine whether a mobility plate is required for a specified carpet.
