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. [. . . ] The first pH calibration buffer: The second pH calibration buffer: The third pH calibration buffer: 24 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 SET key if you want to see calibration date (or time, if old calibration was performed in the same day with current calibration). · Each calibration buffer is displayed with the resolution from calibration moment. · 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. 25 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 key or simply GLP from the left keyboard (HI 120) while in Relative mV measurement mode. The instrument will display the Relative mV GLP information. · The date (yyyy. mm. dd) of the last calibration as in pH GLP mode. Press the ARROW keys to view the next logged calibration parameter (pressing the key): · The Relative mV calibration offset and time (hh:mm) as in pH GLP mode. · The instrument ID as in pH GLP mode. Notes: · Press 2nd then GLP key at any moment and the instrument will return to measurement mode. · If calibration has not been performed, the instrument displays "no CAL" message blinking. 26 SETUP Setup mode allows viewing and modifying the following parameters: · Calibration Alarm Time Out · One-point calibration behaviour · Custom Buffer 1 · Custom Buffer 2 · Alarm High Limit · Alarm Low Limit · AutoLOG Start Condition · AutoLOG End Condition · AutoLOG Interval · Temperature Unit · Current Date (yyyy. mm. dd) · Current Time (hh:mm) · Printing Language (HI 122 only) · Printer Status (HI 122 only) · Beep Status · Baud Rate (serial communication) · Command prefix (serial communication) · Instrument ID To enter SETUP mode, press 2nd then SET key, or simply SET from the left keyboard (HI 120 only), while the instrument is in measurement mode. Select the desired setup parameter using the ARROW keys. Press CAL if you want to change the item value. hour, in setting up the correct time) and "CFM" tag will start blinking. Press the ARROW keys to change the displayed value or simply use the numerical keys for all numerical parameters. Note: To use the numerical keys, press NUM from the left keyboard. The new introduced digit is always the last one. All the previous digits will shift to left. Last introduced digit will be deleted and the number will shift to right.

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. [. . . ]
