Restore Factory Default
If the instrument does not work properly or incorrect settings have been made, confirm Yes with the key
to return all the parameters of the pH menu to the default settings.
IMPORTANT: The factory reset of the parameters does not delete the stored data.
• Automatic COND calibration
Example: one-point calibration (1413 µS / cm) using a cell constant sensor 1
•
In Cond measure mode, keep the button

Rinse the cell with distilled water

Mix with a few ml of standard solution.

and dip the sensor in the standard 1413 µS/cm, keeping it slightly stirred and making
•
sure that there are no air bubbles in the cell.
In the beaker, all the Conductivity values, that the instrument is able to recognize, scroll.

The actual measured value flashes on the display, then, the calibration report appears, showing the
cell constant for each scale and finally, the device automatically returns to measure mode. The beaker
1413

for the calibrated point appears on the bottom of the display.
One-point calibration is enough, if measurements are performed within the measurement range.
•
EXAMPLE: the standard solution 1413 µS/cm is suitable for measurements between 500 – 5000 µS/cm.
•
To calibrate the instrument on several points, once returned to the measure mode, repeat all the
calibration steps.
The beaker relating to the new calibrated point will join the previous one.
It is recommended to start the calibration from the less concentrated standard solution and then
continue in order of increasing concentration.
When a new calibration of a previously calibrated point is performed, it is overwritten on the previous
•
one and the cell constant is updated.
•
For each cell constant, the instrument stores the calibration, to allow the user who uses multiple
sensors with different constants not to be forced to recalibrate each time.
Important: Standard conductivity solutions are more vulnerable to contamination, dilution and
direct influence of CO2 than pH buffers, which, on the other hand, thanks to their buffer capacity,
tend to be more resistant. In addition, a slight change in temperature, if not adequately compensated, can
have significant effects on accuracy. Therefore, pay attention in the calibration process of the Conductivity
cell in order to obtain accurate measurements.
