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. [. . . ] · If necessary, press the ARROW keys to select a different standard value. · The " " tag will blink on the LCD until the reading is stable. · When the reading is stable and close to the selected standard, the CFM functional key is displayed. · The calibrated value and the fourth expected standard value will be displayed. · After the third calibration point is confirmed, immerse the ISE electrode approximately 4 cm (1½") into the fourth calibration solution. · If necessary, press the ARROW keys to select a different standard value. · The " " tag will blink on the LCD until the reading is stable. · When the reading is stable and close to the selected standard, the CFM functional key is displayed. · The calibrated value and the fifth expected standard value will be displayed. · After the fourth calibration point is confirmed, immerse the ISE electrode approximately 4 cm (1½") into the fifth calibration solution. · If necessary, press the ARROW keys to select a different standard value. · The " " tag will blink on the LCD until the reading is stable. · When the reading is stable and close to the selected standard, the CFM functional key is displayed. The instrument stores the calibration value and returns to normal measurement mode. Note: The instrument will automatically skip the standard solutions used during calibration FOUR, THREE, TWO or ONE-POINT CALIBRATION · Proceed as described in "FIVE-POINT CALIBRATION" section. · Press ESC or CAL key after the appropriate accepted calibration point. The instruments will return to measurement mode and will memorize the calibration data. ERROR SCREENS Wrong standard The calibration cannot be confirmed. The message appears if mV input is out of ±2000 mV range. 29 Wrong slope The calibration cannot be confirmed. Slope under accepted value (30 % default slope). Slope over accepted value (130 % default slope). Wrong old slope An inconsistency between new and previous (old) calibration is detected. Clear old calibration parameters and proceed calibration from the current point. The instrument will keep all confirmed values during current calibration. The instrument will display "----" on the primary LCD if is not calibrated or after all calibrations are cleared.
