PUTTING THE UNIT TOGETHER
Cable Connection
Make sure the connectors are clean and dry before connecting!
If connecters are clean and
dry, align the keys on the male cable connector with the female slots on the instrument
connector. Push together firmly, and then twist the outer ring clockwise until it locks into place.
The metal pin should “snap” into place and be visible through the small hole in the outer ring
(see image below).
Sensor Installation
NOTE:
There are two different storage procedures for the sensors and unit:
short term
(sensors
are still attached to the unit), and
long term
(sensors have been removed and individually
stored). If the unit has been stored under the short term procedures, continue to the Calibration
section below.
The ports on the ProDSS bulkhead are universal; therefore, you can install any sensor into any
port. For highest accuracy, always install a conductivity/temperature sensor to compensate all
measurement data for temperature and dissolved oxygen data for conductivity. Similar to the
cable connection, the sensor and bulkhead ports are not waterproof, therefore
always make sure
the ports are clean and completely dry before installation.
Any moisture in the ports will
result in damage to the unit not covered under its warranty.
Avoid sensor installation in the
field at all costs.
