OPERATIONAL GUIDE INITIAL PREPARATION Each meter is supplied complete with a 9V battery. Remove the battery compartment cover on the back of the meter and install the battery while observing 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 probe protective cap before taking any measurements, and make sure the meter has been calibrated. Turn the meter on by pressing the On/Off key.
• Select the appropriate measurement range (EC or TDS). • Wait for a couple of minutes for the temperature sensor to reach thermal equilibrium. The display then shows the measurement automatically compensated for temperature with the appropriate following indication: “mS” tag indicates the meter is in EC mode, while “ppm” tag indicates the meter is in TDS mode. TAKING TEMPERATURE MEASUREMENTS • Submerge the tip (4cm/1½") of the probe into the sample to be tested. • Select the °C mode.
p H 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. e) Whenever the CAL-CHECK test fails (HI 9813-6 only). PREPARATION Pour small quantities of pH 7.01 (HI 7007) or pH 4.01 (HI 7004) or pH 10.01 (HI 7010) solution into a clean beaker. To obtain accurate readings, use pH 7.
pH VALUES AT VARIOUS TEMPERATURES For temperature compensation during calibration, please refer to the following chart. TEMP pH VALUES ºC ºF 4.01 6.86 7.01 9.18 10.01 0 32 4.01 6.98 7.13 9.46 10.32 5 41 4.00 6.95 7.10 9.39 10.24 10 50 4.00 6.92 7.07 9.33 10.18 15 59 4.00 6.90 7.05 9.27 10.12 20 68 4.00 6.88 7.03 9.22 10.06 25 77 4.01 6.86 7.01 9.18 10.01 30 86 4.02 6.85 7.00 9.14 9.96 35 95 4.03 6.84 6.99 9.11 9.92 40 104 4.04 6.84 6.98 9.
EC/TDS CALIBRATION Accessories needed: • Use HI 70031 (1413 μS/cm = 1.413 mS/cm) EC calibration solution or HI 70442 (1500 ppm) TDS calibration solution. Note: The conversion between EC and TDS is made by a built-in circuit, hence it is requested to calibrate the meter only in EC or TDS range. The other range is thus automatically calibrated. PROCEDURE • Pour approximately 4 cm (1½") of a conductivity calibration solution (e.g. HI 7031) into a beaker.
BATTERY REPLACEMENT These meters are powered by a 9V battery that is located on the rear of the instrument. When battery symbol is empty a low battery condition is indicated. When the low battery indication appears, only a few hours of working time remains. It is recommended to replace the battery immediately. When the battery level is so low that it may cause unreliable measurements, the meter turns off. Battery replacement must only take place in a nonhazardous area using a 9V alkaline battery.
CLEANING PROCEDURE For better accuracy in measurements and to ensure a good performance of the probe, a frequent cleaning is recommended. For this purpose, soak it in Hanna HI 700661 Cleaning Solution for 5 minutes. Note: For particular dirty (as for example protein, oil or grease) see the “Accessories” section for Hanna specific solutions. HI 9813-6 only: CAL-CHECKTM FEATURE / CLEAN & CAL PROCEDURE The unique Cal-CheckTM feature allows the user to check the meter calibration status at any time.

RECOMMENDATIONS FOR USERS Before using these products, make sure they are entirely suitable for the environment in which they are used. Operation of these instruments in residential areas could cause unacceptable interferences to radio and TV equipment, requiring the operator to follow all necessary steps to correct interferences. The glass bulb at the end of the electrode is sensitive to electrostatic discharges. Avoid touching this glass bulb at all times.
