Selection of the site
The SalinoMADD may contain up to 15 pre-programmed sites. This programming is usually carried out at home,
although it can be done anywhere by means of a laptop.
Make sure the SalinoMADD is switched off and then connect the
probe. Having switched on the unit and selected ACQUISITION mode
the display shows the name of the first programmed site.
Here are the options you can select:
Next site
Previous site
Accept the displayed site
If this site has been already gauged, the result will be displayed here
or a ? will appear if gauging was not complete and if no result could be
obtained. By choosing a site previously gauged, the measurements
data will be replaced upon Start by the new gauging data.
If a site has not been pre-programmed, it is always possible to
register a site number on site. In this case, having confirmed the
gauging site, a site number for further reference can be registered.
The numeral chosen with the cursor can be stepped up by pressing
touch
and the cursor can be moved to the next numeral pressing
.
If no site number is desired, just leave the number 0000 (pressing 4x
). A registered site number cannot be erased nor altered.
Selecting intervals
After the selection of a gauging site, the display shown at right will appear. You can select the desired interval
between measurements by pressing touch .
Choosing the interval between 1, 2, 4, 8, 16, or 32 seconds is
directly related with the laps of time the salt cloud needs to
completely pass by the gauging site. The total disposable memory for
one gauging site being 955 measurements, the interval may allow
data acquisition during ¼ hour, ½ hour, 1 hour, 2 hours, 4 ¼ or 8 ½
hours.
It is important to adapt the interval to the characteristics of the water course:
• If the watercourse is rapid and turbulent, the injected tracer will be quickly uniformly mixed and this will
permit a fast gauging with an injection of the tracer at a short distance from the gauging area. In this case
a shorter interval is chosen.
• If the water flow is high, the distance of the tracer injection point from the gauging area will be long and
the time for the tracer cloud to pass by the gauging site will be longer. The interval will have to be longer
as well. Experience in gauging with tracers will make the choice of sites and gauging parameters easier.
NB: All operations to select values like the increment of digits, the quittance of option or the confirmation of
menus are always done with help of the 3 touches of the front panel and their explanation will therefore no
longer be repeated.
