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 CSA, UL and (EN 50081-1 and EN 50082-1) directives. TABLE OF CONTENTS PRELIMINARY EXAMINATION GENERAL DESCRIPTION FUNCTIONAL DESCRIPTION AND SPECIFICATIONS: HI8417 HI8519 HI8520 HI8521 OPERATIONAL GUIDE PH CALIBRATION PROCEDURE FOR HI8417 PROCEDURE FOR HI8519 PROCEDURE FOR HI8520/HI8521 CAL. [. . . ] (Note: the "pH" symbol will be flashing throughout the calibration procedure). The buffer value will be CON displayed on the right LCD. · Allow 1-2 minutes for the pH reading to stabilize. The pH reading will be temperature compensated. if the buffer temperature is at 25°C, the right display will show "pH 7. 01". If the buffer temperature is at 20°C, the display will show "pH 7. 03" (see page 23). °C pH If "Err4" appears the calibration solution is wrong. Note: If you are not using the ATC probe, refer to page 22 to manually correct for temperature. · Press the CON key again to accept the buffer value. CON The first point calibration is now complete. · If the pH/mV key is pressed at this point, the calibration process is ended and only the offset of the meter is calibrated. For greatest accuracy, however, it is recommended that a two-point calibration is performed. · Rinse the electrode and the temperature probe before immersing them into pH 4. 01/ pH10. 01 (or 9. 18) calibration buffer, shake briefly and wait for thermal equilibrium. 19 · The meter automatically recognizes the buffer value and prompts for the second at "d2" or "t2" (= pH 4. 01, acid) or "d3" or "t3" (pH 9. 18 and pH10. 01 respectively, alkaline). CON · Press the CON key to confirm the pH value. · The display will indicate the temperature compensated buffer value e. g. if the temperature is at 25°C, the display will show "pH 4. 01" or "10. 01" or "pH 9. 18", depending on the solution being used. If the temperature is at 20°C, the display will show respectively "pH 4. 00" or "pH 10. 06" or "pH 9. 22" (see page 23). °C pH · Press CON key again to confirm calibration. · The pH symbol will stop flashing and the unit is ready for measurements. · If the reading is drifting, turn the meter off and repeat the calibration procedure waiting longer for the reading to stabilize. However, usually 1 or 2 minutes is enough time to prevent a drifting reading. Note: If you need to unplug the instrument, press the OFF key thus switching the instrument off before disconnecting the power cord. In this way the instrument will retain the calibration data. Otherwise, re-calibration might be necessary. In the case of a power failure while the instrument is operational, recalibration might be required. PH CALIBRATION FOR HI8519 Note: If you need to calibrate to NBS standards, use pH 6. 86 (HI7006 or HI8006) and pH 9. 18 (HI7009 or HI8009) instead of pH7. 01 and 10. 01 respectively.
