740 Portable Suspended Solids
4 User Profiles
Understanding the concept of profiles is key to the successful operation of the 740
Monitor. A profile is used to store the configuration and calibration data for a particular
measurement. The 740 Monitor is capable of storing up to ten profiles, the actual
number required will depend upon the number of different measurements to be made.
Normally a separate profile is required for each different measurement to be made, for
example final effluent suspended solids and mixed liquor suspended solids.
4.1 Presets
To reduce the setup time of the 740 Monitor, several preset measurements are
available that the user can choose from when creating a new profile. Each of these
presets contains configuration and calibration data for commonly made measurements.
Note: The presets provide a fast route to completing the instrument setup.
However as they use calibration data established from reference measurements,
it may be necessary to carry out calibration to improve upon the measurement
accuracy.
