These Instruments are in Compliance with the CE Directives
Dear Customer, Thank you for choosing a Hanna Instruments Product. Please read this instruction manual carefully before using the instrument. This manual will provide you with all the necessary information for the correct use of the instrument, as well as a precise idea of its versatility in a wide range of applications. These instruments are in compliance with
PRELIMINARY EXAMINATION
Remove the instrument from the packing material and examine it carefully to make sure that no damage has occurred during shipping. [. . . ] When the "S" symbol blinks in the lower LCD, press ALT and CFM to confirm the second calibration point.
CALIBRATION DATA PRINTOUT
It is possible to print the characteristics of the electrode as a recording of the electrode performance over time by setup code 12 (see "Printing GLP data"). This will consist of: date, time, the offset characteristic of the pH electrode in mV, the slope characteristic in mV/pH and the pH buffer solution values. If calibration has been performed with an "old" pH electrode the first line is: pH ** If calibration has been performed with a "dead" pH electrode the first line is: pH -If the calibration alarm time-out is expired, the "Dt" string will be printed beside the date. Note: A dashed line indicates that the calibration has never been performed.

mV CALIBRATION PROCEDURE
(HI98240 ONLY) A four-point calibration must be performed. The first two calibration points are 0. 0 and +350. 0 mV for low range calibration; the other two calibration points are 0 and +350 or +1900 mV for high range calibration. Connect a mV simulator (HI8427 or HI931001 with the proper connecting cable) to the meter and set it to 0 mV. Press ALT and CAL when LCD is displaying mV.
3. User is prompted to enter password if it has been set to a value different from 0000, otherwise skip to step 6. Press ALT and CFM to confirm the password or ALT and CAL to return to normal operational mode. If password is correct or not set, the meter will display "0. 0 mV" on the upper LCD and "b1" on the lower; if wrong, it will return to normal operational mode without any message. When the "S" symbol blinks in the lower LCD, the reading is stable and calibration can be confirmed. Press ALT and CFM to confirm the first value.
14. When the "S" symbol blinks in the lower LCD, the reading is stable. Press ALT and CFM to confirm the third value. The meter will display "350 mV" in the upper LCD and "b4" on the lower one. Pressing the " " key, 1900 mV will be selected as calibration point. Note: +1900 mV is suggested as the last calibration point to obtain the best accuracy throughout the entire mV range. When the "S" symbol blinks in the lower LCD, the reading is stable. Press ALT and CFM to confirm the fourth value. Calibration is now complete and the instrument returns to normal operational mode. Note: "Err" message notifies the user if the selected value is wrong.
TEMPERATURE CALIBRATION PROCEDURE
( for technical personnel only) The meter is factory calibrated for temperature. It is recommended that the following procedure is performed by authorized technical personnel only. [. . . ] combination ORP / Pt electrode, single junction, gelfilled. · · · · · · · · · · · · · · · · · · ·
