1. The Print key is inactive during a calibration. However, the follow-
ing information is automatically printed out at the end of a calibra-
tion: the instrument ID entered and the date and time (on the top
line) then the buffer pH value(s), potential, temperature and the
measuring time in seconds. The printout then indicates whether a
one, two or three-point calibration was performed, the calibration
temperature, the buffer pH used, the zero pH and sensitivity results.
For example:
*** PHM220 pH Meter 65R00N003
pH AUTO Calibration
Buffer
No.

2. If an error occurs during a calibration, e.g. a sensitivity error, the
printout will contain an error message and warn you that no data
have been stored. For example:
*** PHM220 pH Meter 657R00N003
pH AUTO Calibration
Buffer
No.
2 Point Calibration at 25.0 ˚ C: pH
Zero pH: 7.00 Sensitivity:
SENSITIVITY ERROR:
