• •• •• The pH calibration slope in mV/pH normalized to 25 °C (the
percentage is referred to the ideal value of 59.16 mV/pH).
Note: If you calibrate using electrodes with pin the electrode condition
and response gauges appear while the offset and slope are
displayed.
• The pH calibration buffers in calibrating order and with the selected
resolutions used during calibration.
The first pH calibration buffer:
The second pH calibration buffer:
• If “no bUF” message appears on the LCD, the instrument informs
you that the calibration was performed with less than two buffers.
• Calibration Expiration status:
- if disabled.
- or the number of days until the calibration alarm will be displayed,
- or if expired (7 days ago).
• The instrument ID.
