Please read this instruction manual carefully before using the instrument. It will provide you with the necessary information for a correct use of the instrument, as well as a precise idea of its versatility. If you require further technical information, do not hesitate to e-mail us at tech@hannainst. com. [. . . ] All subsequent measurements will now be compensated to 25°C (77°F). If the instrument cannot be calibrated, refer to the Probe Maintenance section (page 30). You can calibrate the instrument using any other Hanna calibration solution in exactly the same way. For example with HI 7038 turn the trimmer to obtain 6. 44 g/L @25°C. 17 PROCEDURE FOR HI 9039 · Fill a beaker with 8 cm (3¼") of HI 7039 or HI 8039 conductivity calibration solution at 5000 µS/cm @25°C (if possible fill two beakers and use one as rinse and the other for calibration). · Make sure that the probe is connected to the meter securely by aligning the pins with the socket, pushing the plug in and tightening the threaded ring. · Immerse the probe into the beaker. The level of solution must be higher than the holes on the PVC sleeve. · Turn the instrument on by pressing ON/OFF and select the conductivity measurement mode by pressing RANGE. ON/OFF RANGE · Tap the probe repeatedly on the bottom of the beaker and stir it to ensure that no air bubbles are trapped inside the sleeve. · Press CAL to display "5000 µS" together with the "CAL" symbol and an intermittent "BUF" indicator. µS CAL °C CAL BUF · If the reading is within 15% of the theoretical value, the meter automatically recognizes the standard solution and the "BUF" symbol will stop flashing. ·" " will disappear from the display when the reading is stable and the CON "CON" symbol will start blinking. · Press CFM to confirm the calibration reading. Calibration is now complete and the instrument is CFM ready for use. All subsequent measurements will now be compensated to 25°C (77°F). If the instrument cannot be calibrated refer to the Probe Maintenance section (page 30). Press CAL to quit the calibration mode. µS °C CAL 18 PROCEDURE FOR HI 933100 · Make sure that the conductivity probe is connected to the meter securely by aligning the pins with the socket, pushing the plug in and tightening the threaded ring. · Dry the probe and leave it in the air. ON/OFF · Turn the instrument on by pressing ON/OFF. · Press CAL to display "0. 0 µS" together with the "CAL" symbol and an intermittent "BUF" indicator. CAL ·" " will disappear from the display when the reading is stable and the "CON" symbol will start blinking. · Press CFM to confirm the calibration value and exit the calibration mode. CFM · Fill a beaker with 8 cm (3¼") of HI 7031/HI 8031, at 1413 µS/cm @25°C, or HI 7030/HI 8030, at 12880 µS/cm @25°C (if possible fill two beakers and use one as rinse and the other for calibration). · Immerse the probe into the beaker. The level of solution must be higher than the holes on the PVC sleeve. · Tap the probe gently on the bottom of the beaker and stir it to ensure that no air bubbles are trapped inside the sleeve. [. . . ] If under warranty, report the model number, date of purchase, serial number and the nature of the failure. If the repair is not covered by the warranty, you will be notified of the charges incurred. If the instrument is to be returned to Hanna Instruments, first obtain a Returned Goods Authorization number from the Customer Service department and then send it with shipping costs prepaid. When shipping any instrument, make sure it is properly packaged for complete protection. [. . . ]
