Notes: • The “OLd” message displayed beside the pH value means
that this buffer was not used during last calibration. Press
2nd then Setup 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 “not CAL” 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.
LAST RELATIVE mV CALIBRATION DATA
Last Relative mV calibration data is stored automatically after a successful
calibration.
To view the Relative mV calibration data, press 2nd then GLP while in
Relative mV measurement mode.
The instrument will display the Relative mV GLP information.
• The date (mm.dd) and the time (hh:mm:ss) of the last Rel mV
calibration as in pH GLP mode.
Press the ARROW keys to view the next calibration parameter (pressing
the key):
• The Relative mV calibration offset as in pH GLP mode. For the slope
position “----” is displayed.
• The instrument ID as in pH GLP mode.
Notes: • Press 2nd then GLP or only GLP at any moment and the
instrument will return to measurement mode.
• If calibration has not been performed, the instrument displays
“no CAL” message blinking.
• Press 2nd and Setup while date and time are displayed in
order to view the year in the first LCD line.
