3.2.1. Real Time Operation
For real time data output, connect the signal cable to the 10 pin SubConn connector on the
instrument. All Valeport signal cables include a suspension point for strain relief, and a similar
arrangement is recommended for other cable types. Connect the top end of the cable to a PC using
the appropriate method as described above.
3.2.2. Self Recording Operation
For self recording only deployments, the instrument is switched on by insertion of the SubConn style
switch plug. This plug must be inserted for the unit to operate.
3.2.3. Recovery
On recovery, data can be extracted to PC via the 3m Y lead. This is covered in Section 2.
To prolong the lifetime of the instrument the following procedures should be carried out once the
instrument has been recovered:
·
Remove any significant growth from the instrument, taking care not to damage any of the sensor
faces. A high pressure water jet or stiff (not metal) brush is recommended.
·
Remove any significant growth from the pressure sensor port. Take care not to introduce any
sharp objects onto the sensor face – this may result in sensor damage.
·
Check instrument for signs of damage.
·
Rinse the instrument in fresh water
·
Dry the instrument if possible, paying particular attention to the sensors and connector.
·
Repack the instrument in the transit cases provided.
