Stability indication
When the measuring value is stable, smiley icon
appears on LCD.
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)
-High (longer time)
-
Low (shorter time.)
User can select suitable stability criteria according to different testing requirement.
Parameter selection
Only for PC70+DHS, enter in the setup menu P6.6, one by one the parameters blinks on the top left of the LCD;
press
and
keys for choose Yes (parameter enabled) or No (parameter disable) .Then press
key to
confirm. Press
key to return in measurement mode.
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. In the automatic storage mode, the automatic power off is not
possible.
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:
To calibrate the DHS sensor follow the calibration procedure at page 10 (pH meter calibration).
When the DHS electrode is disconnected, display shows:
Note: DHS activation and disabling occur only in measurement mode.
