That's right. And for those not familiar with the indicator. The pointer represents the displacement of the actuator from the central position. One indicator for each linear actuator. The selector knob selects the axis you wish to monitor. So the indicator can monitor all six linear actuators (i.e. three pairs). Normal presentation is the pointer for each actuator darting about the central position, with each pointer more-or-less moving in the same direction at the same time. Abnormal indication is one pointer stopped whilst the other pointer is moving twice as far as normal, or pointers moving in opposite directions to each other, or "hard-over" one full left whilst the other full right.
