Opening and closing a compact instrument

RBR compact instruments have two O-rings. Remember to keep the O-rings clean and avoid scratching the O-ring mating surfaces. Carefully inspect the O-rings before deploying the instrument.

Opening the instrument

  1. Hold the instrument with the sensor end-cap up.

  2. Unscrew the sensor end-cap, counterclockwise.

  3. Once fully unscrewed, slide the housing away from the sensor end-cap to reveal the sensor carriage.

Closing the instrument

  1. Insert the sensor carriage into the housing.

  2. Screw the sensor end-cap back on, clockwise.

The sensor carriage contains the battery compartment, desiccant holder, and USB-C port.

When opening the RBRsolo³ Tu, make sure to unscrew the end-cap at the red ring. The black coupler is part of the turbidity sensor end-cap and should stay intact. See Coupling of the turbidity sensor.
