Sensors With Dhs Technology; Errors During Calibration; Mv Parameter - XS Instruments Revio Manual De Instrucciones

To eliminate any error due to user interpretation, it is possible to use the "HOLD" function (See
paragraph Instrument Setup Menu), which allows you to block the measurement as soon as it reaches
stability.
• After the measurement, wash the electrode with
distilled water and preserve it in the appropriate
storage solution. Never touch the sensors in the
distilled water.
Note: the graphical representation of the electrode at
the bottom left of the display indicates the slope of the
current calibration.
The possibility to have immediate access and manage all
the information regarding the calibration and the status of the sensor allows the user to work while
maintaining high quality standards.
IMPORTANT: the use of the wide range of XS Sensor electrodes is preferred and it the solution
recommended by the manufacturer to obtain highly accurate measurements. Read carefully the
instructions and recommendations for use and maintenance, which are always present inside the
packages of XS Sensor electrodes.

• Sensors with DHS technology

The electrodes equipped with DHS technology can save a
calibration curve within their memory. The calibrated sensor is
automatically recognized by any instrument enabled for DHS
recognition and acquires its calibration.
Connect the DHS electrode to the BNC and RCA connectors of
•
the instrument in the green inputs.
The device automatically recognizes the chip; information on
•
the model, sensor lot and last calibration data (if the electrode
was already calibrated) appear on the display.
• When the DHS electrode is recognized, the active calibration on the instrument becomes the one of
the sensor.
The sensor is ready to be used.
•
• When the electrode is disconnected, a message on the display informs the user of the deactivation of
the sensor; the instrument regains its previous calibration and no data is lost!
• The DHS electrode does not require batteries and if it is used on pH meters that are not enabled to
recognize the chip, it works as a normal "analog" electrode.
Consult your local distributor for more information on the pH-meters (bench and portable) produced
•
by the suppliers compatible with DHS sensors.

• Errors during calibration

• NOT STABLE MEASURE: The button

• WRONG BUFFER: The buffer is polluted or not part of the recognized families.
• CALIBRATION TOO LONG: The calibration exceeded the time limit: only the points calibrated up to that
moment will be kept.
