If the readings are satisfactory, log pH 7 reading and press 1; if the readings are suspect, press
2 to return to step 16.
19. After accepting the pH 7 buffer readings, the Instrument will determine if each electrode’s
response is sufficient to provide suitable readings. A score is displayed for each electrode; the
acceptable score range is between 75 and 102. If both electrodes are within this range, the
instrument will display the following screen:
20. If an ‘X’ is displayed beside one or both electrodes’ scores, this indicates that one or both of the
electrodes did not perform well enough for continued reliable use. No calibration settings are
changed if calibration is unsuccessful. The electrode(s) responsible for failed calibration should
be removed and either cleaned or replaced and the calibration procedure repeated. See
Maintenance section for electrode cleaning instructions.
21. After calibration is complete, you will have the option to use the calibrated readings or reset to
the default parameters.
22. The results of calibration are stored in a file on the instrument. for instructions on downloading
