Please read this instruction manual carefully before using the instruments. This manual will provide you with the necessary information for correct use of the instruments, as well as a precise idea of their versatility. [. . . ] · When an abnormal condition in the RTC is detected, the instrument forces the "expired calibration" status. LAST pH CALIBRATION DATA The last pH calibration data is stored automatically after a successful calibration. To view the pH calibration data, press 2nd then GLP when the instrument is in pH measurement mode. The instrument will display the time (hh:mm) of the last calibration. Press the ARROW keys to view the next calibration parameter (pressing the key): · The date (mm. dd. yyyy) of the last calibration. · The pH calibration offset. 22 · 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 calibrating order, for the last calibration. 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 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 "no bUF" 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. · The instrument ID. 23 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 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 date as in pH GLP mode. · The Relative mV calibration offset as in pH GLP mode. · The instrument ID as in pH GLP mode. Notes: · Press 2nd then 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.

Operation of these instruments in residential areas could cause unacceptable interferences to radio and TV equipment, requiring the operator to follow all necessary steps to correct interferences. The glass bulb at the end of the pH electrode is sensitive to electrostatic discharges. Avoid touching this glass bulb at all times. [. . . ]
