Automatic Ph Calibration - Giorgio Bormac 8+ Série Manuel D'utilisation

P1.8 Restore factory default.
If the instrument does not properly work or incorrect calibration were performed press Yes with
return all pH parameters to the factory default settings.
IMPORTANT: the factory reset of the parameters does not delete stored data.

• Automatic pH calibration

Example for 3 points USA buffers calibration
• In pH measurement mode press and hold for 3 sec "
In PC devices pH calibration can be accessed also from simultaneous pH/Cond screen then selecting pH.
• Rinse the electrode with distilled water
Press and immerse the electrode in the pH buffer 7.00 (as indicated by the becker on the display).
The first calibration point is always the neutral pH (7.00 for USA buffer, 6.86 for NIST and DIN buffers)
while the others are at the discretion of the user.
• When the icon appears on the display confirm the first calibration point pressing
The display flashes the value measured and then the pH 7.00 icon becker appears at the bottom left
