Steps for the Slow leak test
Prepare for this test with the inspection equipment pressures Compliant and
adequate, then:
• Take a note of the inspection equipment pressures, then leave the
equipment powered on and unused for 30 minutes.
• After 30 minutes, the pressures of the equipment should not have
appreciably decreased (it is OK if the pressures have increased; this is due
to the internals of the inspection equipment warming up).
• If pressures HAVE appreciably decreased, or a pressure WARNING is
showing, the inspection equipment is NOT suitable for ATEX.
If this test fails, do not use the equipment for ATEX, and consult your
Mini-Cam Service team.
Steps for the Pressure-Drop Test
Prepare for this test with the inspection equipment pressures Compliant and
adequate, then:
• Ensure the OVERRIDE key is in the ATEX position.
• Turn up the camera illumination (see section "Camera Function Keys"
in the Proteus Original Instruction Manual) such that the camera lights
are visibly ON.
• Manually cause a release of the inspection equipment pressure, by
opening the purge valve slowly on the device.
The system should show a series of warnings as the pressure drops:
• Pressure low advisory
• Pressure low caution
• Pressure non-compliant
