Performing Ph Measurement - Xs Instruments 70 Serie Manuel D'utilisation

 When the icon appears again, press the key
value flashes on the display and the beaker icon appears with the buffer identification colour
 Remove the electrode, rinse with distilled water, dab it gently with paper towel and dip it in the next
buffer (e.g. pH 4.65).
 Wait for the pH value on the display to stabilize; when the icon
flashes, modify it using the directional keys by entering the correct one (e.g. pH 4.65), as suggested by
the string "ADJUST THE VALUE" and by the icon
 When the icon
measured value flashes on the display, the Slope% and, next to the first beaker, the icon with the
identifying colour of the second buffer
At the end of the second calibration point, the instrument automatically returns to measure mode.

 To perform a one-point calibration just press the key
Note: If you are working with manual temperature compensation (MTC), update the value before calibrating
the instrument.
 Performing pH measurement
In measure mode, press the button

 Connect the electrode to the pH / ORP BNC of the instrument (green).
 If the user does not use an electrode with a built-in temperature probe or an external probe NTC 30KΩ,
it is recommended to manually update the temperature value (MTC).
Remove the electrode from its tube, rinse with distilled water and dab gently with paper towel.

 Check the presence and eliminate any air bubbles in the membrane bulb by stirring vertically (as for
the clinical thermometer). If present, open the side cap.
 Dip the electrode in the sample, while keeping it slightly stirred.
The scrolling on the display of four red bands

 Consider the measurement truthful only when the stability icon appears
Example of an unstable measurement
After the measurement, wash the electrode with distilled water and preserve it in the

appropriate storage solution (STORAGE).
 Never store the sensors in ANY TYPE of water OR DRY!
 It is a useful tool for obtaining accurate measurements always having on the display the indication of
the buffers used for calibration and the possibility of consulting the calibration data, at any time, or
entering the expiry date.
