OPERATIONAL GUIDE INITIAL PREPARATION Each meter is supplied complete with a 9V battery. Slide off the battery compartment cover on the back of the meter (see page 16), install the battery while paying attention to its polarity. Connect the probe to the DIN socket on the top of the meter by aligning the pins with the socket and pushing in the plug. Always remove the electrode protective cap before taking any measurements.
p H CALIBRATION EC/TDS CALIBRATION For greatest accuracy, frequent calibration of the instrument is recommended. The instrument should be recalibrated for pH: a) Whenever the electrode is replaced. b) At least once a month. c) After testing aggressive chemicals. d) Where extreme accuracy is required. Accessories needed: • Use HI 7039 or HI 8039, 5,000 µS/cm EC solution or HI 7032, 1382 ppm TDS solution.

ELECTRODE CONDITIONING AND MAINTENANCE HI 1285 is a combined pH/EC/TDS electrode with built-in temperature sensor for EC/TDS automatic temperature compensation. The probe screened cable is 1 m (3.3") long. PREPARATION Remove the protective cap. DO NOT BE ALARMED IF ANY SALT DEPOSITS ARE PRESENT. This is normal with pH electrodes and they will disappear when rinsed with water. During transport tiny bubbles of air may have formed inside the glass bulb.

BATTERY REPLACEMENT All meters are powered by a 9V battery that is located on the rear of the instrument. When the battery becomes weak reaching a certain threshold, the istrument automatically switches off. Replacement must only take place in a nonhazardous area using an alkaline 9V battery. To access the battery, remove the battery cover by applying pressure in the direction indicated. Replace the old battery with a new one while paying attention to its polarity.
WARRANTY CE DECLARATION OF CONFORMITY All Hanna Instruments meters are warranted for two years against defects in workmanship and materials when used for their intended purpose and maintained according to instructions. The electrodes and the probes are warranted for a period of six months. This warranty is limited to repair or replacement free of charge. Damages due to accident, misuse, tampering or lack of prescribed maintenance are not covered.
