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:
