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 instruments will display the time (hh:mm) of the last calibration. These instruments allow the user to set the number of days before the next required calibration. Note: If the instruments were not calibrated, the CAL INTV tags will be displayed even if the feature is disabled in SETUP menu. LAST CALIBRATION DATA Press the ARROW keys to view the next logged calibration parameter (pressing the ºC key): The date (yyyy. mm. dd). CAL DATE The pH calibration offset. CAL mV 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). CAL % 15 The pH calibration buffers in calibrating order. The first pH calibration buffer: CAL pH BUFFER pH BUF The second pH calibration buffer: CAL pH BUFFER pH BUF The third pH calibration buffer: CAL pH BUFFER pH BUF Note: For HI 112 and HI 113, the fourth and the fifth calibration buffers are also displayed in GLP. The OLd message displayed beside the pH value means that this buffer was not used during last calibration. Press and hold down 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). CAL BUF pH resolution during calibration. CAL Calibration Alarm Time-Out status: if disabled. 16 or the number of days until the calibration alarm will be displayed. or if expired (7 days ago). CAL INTV The instrument ID. Note: Press GLP at any moment and the instruments will return to measurement mode. If calibration has not been performed, the instruments display no CAL message blinking. CAL Setup mode allows viewing and modifying the following parameters: Calibration Alarm Time-Out Custom buffer 1 Custom buffer 2 One-point calibration behaviour Instrument ID (HI 112 & HI 113) Current Time Current Date Beep Status Baud Rate (serial communication, HI 112 & HI 113) Command prefix (serial communication, HI 112 & HI 113) To enter SETUP mode press SET while the instrument is in measurement mode. 17 SETUP CALIBRATION ALARM TIME-OUT SET Press CAL when the calibration time-out is displayed. Calibration time-out (OFF or 1 to 7 days) will start blinking. CAL INTV Press the ARROWkeys to change the calibration time-out value. FIRST CUSTOM BUFFER SET Press CAL when custom buffer 1 is displayed. The custom buffer (disabled no cb1 or 0 to 16 pH) will start blinking. CAL BUFFER pH Press CAL when custom buffer 2 is displayed. The custom buffer (disabled no cb2 or 0 to 16 pH) will start blinking. CAL BUFFER pH Press the ARROW keys to change the custom buffer value. SECOND CUSTOM BUFFER SET Press the ARROW keys to change the custom buffer value. ONE-POINT CALIBRATION BEHAVIOUR Press CAL when 1 Pnt message is displayed on the secondary LCD. One of the two options (Pnt or OFFS) will start blinking (see pH CALIBRATION PROCEDURE for details, page 11). CAL Press the ARROW keys to toggle between Pnt and OFFS options. 18 INSTRUMENT ID PARAMETER SET (HI 112, HI 113 only) Press CAL when the instrument ID is displayed. The instrument ID (0000 to 9999) will start blinking. Press the ARROWkeys to change the instrument ID value. The hour will start blinking. TIME Press the ARROWkeys to change the hour. The minutes will start blinking. TIME Press the ARROW keys to change the minutes. The year will start blinking. DATE Press the ARROWkeys to change the year.
