Stability indication

When the measuring value is stable, smiley icon
If the smiley icon does not appear or flash, please do not get the reading value, or make calibration until the measuring
value is stable.
In the parameter P1.6, there are 3 criteria for stability standard:
-Normal (default)
User can select suitable stability criteria according to different testing requirement.

Parameter selection

Only for PC7+DHS, enter in the setup menu P6.6, one by one the parameters blinks on the top left of the LCD;
press and
confirm. Press

Automatic Power Off

If the meter stops operation for 20 minutes, It will turn off automatically. In the setup menu P6.8 the user has the
possibility to disable this option.

DHS Technology

DHS technology, developed by Giorgio Bormac company, allows to save calibration data inside the memory of the pH
electrode.
It is possible to calibrate the XS DHS electrode in laboratory, in ideal conditions, using a XS DHS meter.
Calibration data, like date, slope, model and batch number, are memorized inside the electrode.
Moving this electrode on another XS meter DHS compatible, the electrode is ready for high quality measurement,
extremely safety and without a new calibration.
Simply useful: XS Meters DHS compatible recognize automatically If a XS sensor DHS is connected.
If not, the instrument will work as a standard pH meter.
And the same is for the electrode: Is possible to connect a XS sensor DHS on a standard XS meter (NO DHS compatible)
It will work as a standard pH electrode.
XS DHS sensors use just a BNC plug for the pH, and a RCA/Cinch plug for the temperature, exactly the same connectors
of the standard XS electrodes.
And It hasn't the battery, so It is possible to stock the electrode as normal one.
After connecting the XS electrode DHS, meter will recognize It automatically, and display sequentially:
pH
To calibrate the DHS sensor follow the calibration procedure at page 10 (pH meter calibration).
When the DHS electrode is disconnected, display shows:
DHS activation and disabling occur only in measurement mode.
