User Interface, functionality and maintenance
At this point a confirmation request will appear on the display. By pressing the
"SETTING" button again, you are confirming instrument reset. Waiting without pressing
for 10 seconds cancels the reset and the instrument will resume normal operation.
Calibration
To access the calibration functions, press and hold the "SETTING" button. The
instrument will switch off but you must continue to keep the button pressed until it
switches on again. At this point the calibration procedure will start.
This procedure involves calibration on 3 points respectively at:

1413µS/cm

5000 µS/cm

12880 µS/cm
For calibration it is recommended to use only certified solutions.
Before carrying out a new calibration please make sure that the probe is clean. We suggest
using denatured ethyl alcohol, see “Maintenance” paragraph.
Before and between each measurements it is important that the probe is thoroughly rinsed
in distilled water to prevent residues from polluting the next solution.
For each measuring point, the instrument will indicate the measuring point it expects to
measure. Press the "SETTING" button to begin reading and "READING" will appear on
the second line
A sound signal notifies the end of the reading and the request to move on to the next
solution.
At the end of the calibration procedure the instrument will resume normal operation.
Maintenance
To keep your instrument in perfect condition, remember to carefully clean the cable and
sensor and dry them with a soft cloth after use.
NOTICE:
Since the probe takes a few minutes to accurately read the temperature, it is very
important that, before starting a calibration procedure, the probe and solutions are all
at room temperature.
