Vacuum Test

To perform a vacuum test on the BlueROV2, you’ll need the vacuum pump included in your kit. It’s important to do a vacuum test before putting the ROV in the water for the first time, and after any of the following:

• Assembling a new ROV
• Replacing any O-rings
• Installing or replacing a penetrator
• Replacing enclosure parts, like the dome or end cap

You don’t need to vacuum test every time you open an enclosure—like for battery swaps—unless one of the above changes was made.

The step-by-step vacuum test procedure is provided here.

Pre-Dive Checklists

Comprehensive Checklist

This checklist is more thorough than the Pre-Dive Checklist and should be done in a couple of circumstances:

• After travel by airplane
• After extended travel by car or boat (>1 hour)
• After taking off the electronics enclosure
• After replacing or exchanging penetrators
• After replacing any sealing O-ring

Comprehensive Checklist

• Check that the ROV has connected to QGroundControl.
• Tighten the M5x16 screws that hold the frame to the center and bottom panels using the short part of the M3 hex key as the handle or an M3 hex driver.
• Tighten the M3x12 screws that hold the back end caps to the flange seals using the M2.5 hex driver.
