Abstract: A mechanical gauge having a mechanism for setting multiple alarms within tolerance values. When such tolerance values defined by the mechanism are reached, the same mechanism activates an alarm.

Abstract: A gauge having adjustable activating means—for activating, say an alarm—in which multiple alarm points—or tolerance value regions—can be set, comprising: a movement case including a front open portion and a back portion, a gauge movement responsive to a sensed condition located inside the case and driving a rotary gauge shaft and an indicator needle indicating said sensed condition on a scale dial, wherein the adjustable activating means comprising: a plurality of at least two rotating adjusting guides mounted on the rotary gauge shaft; activating means attached to each adjusting guide; bump means for each rotating adjusting guide, said bump mean restricting the rotation of each adjusting guide thus defining a limited rotation arc thereof which is representative of a predetermined range in a scale dial; cam means coupled to the rotary gauge shaft close to the plurality of adjusting guides, said cam means rotating together with the rotary gauge shaft and defining a circular path as the
