OBS500 Smart Turbidity Meter with ClearSensor™ Technology
• The probe must be calibrated with sediments from the waters to be
monitored. The procedure for calibrating the probe is provided in Section
7.5, Calibration.
• Sites with high sediment loads or large sand grains can be problematic for
the shutter and its motor. Refer to Section 7.7, Operation in High
Sediment Loads and Sandy Sediments, for more information.
• The OBS500 will be damaged if it is encased in frozen liquid.
• Use electrical tape or neoprene to pad the parts of the OBS500 housing
that will contact metal or other hard surfaces.
• Remember that although the OBS500 is designed to be a rugged and
reliable device for field use, it is also a highly precise scientific instrument
and should be handled as such.
3. Initial Inspection
• Upon receipt of the OBS500, inspect the packaging for any signs of
shipping damage, and, if found, report the damage to the carrier in
accordance with policy. The contents of the package should also be
inspected and a claim filed if any shipping-related damage is discovered.
• When opening the package, care should be taken not to damage or cut the
cable jacket. If there is any question about damage having been caused to
the cable jacket, a thorough inspection is prudent.
• The model number is engraved on the housing. Check this information
against the shipping documentation to ensure that the expected model
number was received.
• Refer to the Ships With list to ensure that all parts are included (see
Section 3.1, Ships With).
