Discussing SCAMP Maintenance

TESTING FOR LEAKS

PME supplies a squeeze bulb and connecting hose for leak testing the SCAMP. Leak testing is recommended whenever the batteries are replaced and absolutely required every time a sensor is replaced.

  1. To leak test the SCAMP, unscrew the 10-32 stainless screw from the release endcap. Remove the adaptor from the tubing connecting it to the squeeze bulb.   It is much easier to align it with the treaded hole in this condition.  Screw the adaptor into the exposed port. Be careful not to cross-thread this connection.  Push the tubing back onto the adaptor.

  2. Squeeze the bulb several times until no more air can be forced into the SCAMP.

  3. Hold the SCAMP with the sensors up and check for bubbling into the water within the sensor cover.

  4. Place each end of the SCAMP in a bucket and check for bubbles coming from the endcap seals. In the case of the release endcap check for bubbles coming from the release screw, the pressure transducer port or the I/O connector.

When testing is completed, dry the area around the adaptor, then unscrew and remove it.  Replace the stainless screw immediately. Don't forget! The SCAMP will become flooded if this screw is not replaced.  Bubble testing is complete.
