• 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 order.
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 and hold
down the
SETUP
key if you want to see calibration date (or time
if old calibration was performed on the same day as the current
calibration).
• If “
no bUF
” message appears on the LCD, the instrument
