SET
if you want to see calibration date (or time, if old
calibration was made in the same day with current calibration).
For each custom buffer used in calibration, the BUFFER pH tag
will blink.
If no bUF message appears on the LCD, the instrument informs
you that calibration was performed in less than three (
HI 110
,
HI
111
) or five points (
HI 112
,
HI 113
).
