Calibration With Manual Values - XS Instruments Revio Manual De Instrucciones

• Remove the electrode, rinse with distilled water
• Press the button
and dip the sensor in the pH 10.01 buffer solution.
In the beaker the different pH-buffers, that the device can recognize
automatically, scroll.
• When the value 10.01 is recognized and the icon
confirm by pressing the button
Switching from an acidic to a basic pH may take a few more seconds to achieve stability.
The actual measured value flashes on the display and subsequently, next to the beakers of pH 7.00 and
pH 4.01, the icon of the beaker pH 10.01

by pressing .
The calibration report and the graphic representation appear on the display; press the button
to exit and return to measure mode.
The buffers used for the last calibration are displayed in the lower left side.
Note: electrode calibration is an essential operation for the quality and truthfulness of a
measurement. Therefore, make sure that the buffers used are new, unpolluted and at the same
temperature. After a long time or after reading of particular samples, it is necessary to renew the
calibration; the graphic report can help the user in making this decision.
IMPORTANT: in order to obtain highly accurate results, the manufacturer recommends the use of XS Solution
buffer solutions and XS Sensor pH electrodes. Contact your local distributor for supply.
ATTENTION: Before proceeding with the calibration operations, carefully consult the safety data sheets
of the substances involved:
Calibration buffer solutions.
•
• Storage solution for pH electrodes.
• Filling solution for pH electrodes.
The careful reading of the safety data sheets of the solutions used favors the elimination of residual
risks related to skin, contact, ingestion, inhalation or eye contact that can generate possible but not
probable minor damages.

• Calibration with manual values

Example: two-point calibration pH 6.79 and pH 4.65 (DIN19267)
