Creating a New Calibration
To create a new calibration, enter the calibration section and press “New Cal”. Type a name
in the calibration name text box. Select the Calibration Type, the options available (depends
on the connected sensor) are: Linear, Quadratic or Brix. Select the required Tolerance and
the Measurement Mode to display (All modes are calibrated at the same time but only one is
displayed).
Select the “Edit Points” button to start creating the calibration.

Adding a Calibration Point
Averaging the output of the sensor over a period of time is essential for representative
sampling in most applications. In the case of a Hydro-Probe mounted in a sand bin, once the
gate opens the sand starts to flow until the gate closes. As the readings vary during this time
the most reliable way in which to obtain a representative Unscaled value is by continuously
averaging during the flow.
2.5
Averaging Mode
The Averaging Mode used while calculating the Average Unscaled can be set to either ‘Raw’
or ‘Filtered’ (Page 48). For applications where mechanical apparatus, such as mixer paddles
or screws, pass over the sensor and affect the reading the use of the ‘Filtered’ value will
remove the peaks and troughs in the signal. If the material flow is stable, for example, when
measuring at the output from a silo or on a conveyor belt, the averaging should be set to
‘Raw’.
See the Hydronix Sensor Configuration and Calibration Guide HD0679 or the
appropriate sensor user guide for more details on how to set the averaging
functionality for specific applications.
2.6
Automatic Averaging
Digital input 1 can be used to determine when to start the averaging. For a bin installation the
sensor input may be generated from the bin-gate switch to give a +24VDC input when the
gate is open. The same set-up can be used for other installation such as conveyor belts. A
manual switch can be installed to indicate when the sensor should start averaging.
In both cases the configuration of the sensors digital input has to be set to ‘Average/Hold’ for
this purpose (Page 46).
See the Hydronix Sensor Electrical Installation Guide HD0678 or the appropriate
sensor user guide for more details on how to wire the digital input.
2.7
Remote Averaging
If the installation is without an input that can switch to control the averaging function, Hydro-
View has the facility to manually select the start and stop period of averaging. This is called
‘Remote Averaging’ (Page 46).
