Emergency Locking
The electrical connections between the lid electronics and the rest of the
instrument are via a 150mm ribbon cable so it is acceptable to rotate the lid
slightly to ease it from its seal. Be careful not to rotate it too far - 10° or so
in either direction is a safe limit. If the lid proves very hard to move, a flat-
headed screw-driver can be inserted into the small slot formed by a cut-out
in the top of the cylinder and used for leverage:
5. Lift the lid away from the cylinder and, wearing an anti-static wrist-band,
disconnect (at either end) the ribbon cable connecting it to the lower
electronics:
6. Using the 2mm hexagonal driver, remove the screws around the bottom edge
of the cylinder and gently prise the cylinder away from the base. Take
extreme care not to knock any of the sensor components.
