OPERATIONAL GUIDE PROBE CONNECTION & MAINTENANCE In order to protect the DIN connector against vapors and humidity, the meter is provided with a waterproof sheath. · Slide the protective sheath down, connect the HI 1220 probe to the DIN connector and then slide the protective sheath back up. To ensure maximum protection, make sure the connector is completely covered. TDS TDS CALIBRATION For better accuracy, a frequent calibration is recommended. Moreover, the instrument should be recalibrated at least once a month, after cleaning the probe or replacing the batteries. · Press and hold the ON/OFF button for approx. The display will start blinking EC 5. 00 "1500 ppm" for HI 981409 and "5. 00 ms" for HI 981410 to indicate that the calibration mode has been entered. · Immerse the probe in the proper calibration solution: use HI 70442 (1500 TDS ppm) for HI 981409, or HI 70039 (5. 00 mS/cm) for HI 981410. · Stir gently and wait for approximately 20 seconds for the meter to perform the automatic calibration. ON/OFF BATTERY REPLACEMENT When the batteries are weak, EC and TDS will display the warning symbol "Eb". To replace the batteries, remove the rear panel and replace both batteries, while paying attention to their polarity. Batteries should only be replaced in a safe area and using 1. 5V AA alkaline batteries. CE DECLARATION OF CONFORMITY DECLARATION OF CONFORMITY We Hanna Instruments Srl Via E.
