Calibration With Manual Values - XS Instruments 8+Serie Manual De Instrucciones

The calibration report and graphic representation are displayed, press
measurement mode. Bottom left are displayed buffers used for the last calibration.
• Example for 3 Points Calibration
for 8+ Series
• Example for 5 Points Calibration
for 80+ Series
Note: calibration of the electrode is a fundamental operation for the quality and veracity of
measurement. Make sure that the buffers used are new, not polluted and at the same
temperature. After a long time or after reading special samples renew the calibration, the
graphical report can help the user making this decision.
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. Contact your local distributor for more information.

• Calibration with manual values

Example for a two-points calibration pH 6.79 and pH 4.65 (DIN19267)
Enter in the pH setup menu and set in P1.1  USER, press
•
• Press and hold for 3 sec "
• Rinse the electrode with distilled water
• Press and immerse the electrode in the first buffer solution (ex pH 6.79).
• Wait for the stability, when
to adjust the value by entering the real buffer value (ex pH 6.79).
Note: Check the buffer value according to the temperature
• When icon reappears press
the actual measured value flashes on the display and the becker icon appears with the identifier color
and the buffer value at the bottom left
• Extract the electrode, rinse with distilled water
key to continue calibration and immerse the electrode in the next
buffer (ex pH 4.65).
• Wait for the stability, when
to adjust the value by entering the real buffer value (es pH 4.65).
