A suspended movement measuring device assembly comprising: a bracket of a measuring device that includes an adjustment cam, the bracket securedly attached to a socket; a condition responsive element of the measuring device that includes an element inlet and an output end configured to produce motion in response to condition changes (i) received at the element inlet and (ii) to which the condition responsive element is sensitive; an amplifier that includes a sector arm, wherein the amplifier is secured to the output end of the condition responsive element for communicating correlated but amplified motion of the condition responsive element to an indicator shaft for operating a measuring device indicator relative to condition changes on a dial face of the measuring device; an actuator that includes at least a first actuator segment that is positioned within an elongated slot of the sector arm for defining a pivot axis for the sector arm to enable amplifier operation; a second actuator segment of the actuator that is engagably pre-loaded against the adjustment cam to push and ride against a cam surface of the adjustment cam, wherein the second actuator segment is retained in the adjustment cam by a slot provided in the adjustment cam; a third actuator segment of the actuator, the third actuator segment being securedly engaged with a bracket push plate of the bracket, wherein the dimension between the bracket push plate and the adjustment cam is adapted to vary as the adjustment cam is rotated; and a fourth actuator segment of the actuator is securely attached to a bracket weld plate of the bracket; wherein the adjustment cam is configured and dimensioned so that the cam surface that pushes against the second actuator segment changes the position of the first actuator segment in the elongated slot of the sector arm when the adjustment cam is rotated to adjust the span of the measuring device; and wherein the adjustment cam further includes a cam adjustment feature located on the front side of the bracket to allow an operator to adjust the span of the measuring device from the front of the measuring device with the dial face and the measuring device indicator in place on the measuring device; characterized in that the adjustment cam is securedly attached to the bracket via a washer that grips and holds the adjustment cam against a face of the bracket, which thereby imparts a load on the adjustment cam; the slot of the adjustment cam is adapted to rotate together with the adjustment cam when the adjustment cam is rotated; and the adjustment cam includes at least two positive stops configured and dimensioned to stop the cam from rotating or turning when the second actuator segment engages or comes in contact with either positive stop. a bracket of a measuring device that includes an adjustment cam, the bracket securedly attached to a socket;
