• The pH calibration slope (the GLP slope is the
average of the calibration slopes; the percentage
is referred to the ideal value of 59.16 mV/pH).
• The calibration buffers in calibrating order, for the
last calibration.
The first pH calibration buffer:
The second pH calibration buffer:
The third pH calibration buffer:
The fourth pH calibration buffer:
The fifth pH calibration buffer:
Notes:
• The “OLd” message displayed beside the pH value means that this
buffer was not used during last calibration. Press

if you want to see calibration date (or time, if old calibration was
performed in the same day with current calibration). In this case,
the calibration buffer number is not displayed on the LCD.
• If “no bUF” message appears on the LCD, the instrument informs
you that calibration was performed in less than five points.
• The Calibration Alarm Time Out status.
If disabled,
or the number of days until the calibration alarm will be displayed (e.g.
5 days), or from the time calibration expired (e.g. –3 days).
• The instrument ID.
