Systems and processes may provide field-initiated testing and/or control of fluid regulatory systems. In one aspect, a fluid regulatory testing system may include a field test initiator and a fluid regulator control system. The field test initiator may alter control signal delivered to the fluid regulator control system upon activation of a user input device. The fluid regulator control system may receive control signals from the field test initiator and generate fluid regulator control signals. The fluid regulator control system may also detect whether a control signal has been altered, and initiate a fluid regulator testing sequence, if the control signal has been altered. The fluid regulator control system may include a latch mode. When a latch mode is commenced, generation of fluid regulator control signals based on received control signals and/or alteration of a position of a fluid regulator may be inhibited.
