Operation of this instrumentin residential area could cause unacceptable interferences toradio and TV equipments, requiring the operator to take allnecessary steps to correct interferences.The glass bulb at the end of the pH electrode is sensitive toelectrostatic discharge. Avoid touching this glass bulb at all times.For calibration it is recommended to use an antistaticscrewdriver.Any variation introduced by the user to the supplied equipmentmay degrade the instrument's EMC performance. To avoidelectrical shock, do not use this instrument when voltages at themeasurement surface exceed 24 Vac or 60 Vdc.To avoid damages or burns, do not perform any measurement inmicrowave ovens.MAINTENANCE• Separate the compartment from the tester.• Remove deposits formed on the liquid junctionand pH glass bulb by soaking in HI 7061 cleaningsolution for 30 minutes.• Soak the platinum wire in acetone for 30 minutes.• Rinse glass bulb, platinum wire and liquid junc-tion thoroughly with distilled water• Re-assemble the compartment and the tester.• Fill the compartment with tap water.BATTERY REPLACEMENTWhen the Water Test cannot be switched on or thedisplay fades, pull out the battery cover and replaceall three 1.5V batteries, while paying attention to theirpolarity. Battery replacement must only take place ina safe area and using the battery types specified inthis instruction manual.ACCESSORIESHI 7004M pH 4.01 buffer solution, 230 mLHI 7004L pH 4.01 buffer solution, 500 mLHI 7007M pH 7.01 buffer solution, 230 mLHI 7007L pH 7.01 buffer solution, 500 mLHI 7010M pH 10.01 buffer solution, 230 mLHI 7010L pH 10.01 buffer solution, 500 mLHI 7031M 1413 μS/cm conductivity solution, 230 mLHI 7031L 1413 μS/cm Conductivity solution, 500 mLHI 7061M General cleaning solution, 230 mLHI 7061L General cleaning solution, 500 mLHI 731326 Calibration screwdriver (20 pcs)GENERAL DESCRIPTIONThe Water Test is a "four-in-one" portable meter designed for quickand reliable measurement of the four most important variables inwater analysis: pH, ORP, conductivity and temperature.Water Test is engineered with great simplicity, that even non-techni-cal personnel can use it: just fill the base with the sample to bemeasured, press the RANGE key to select the mode and read themeasurement.Water Test is perfect for use in the fields of water treatment analysis,wastewater test, ecological studies, aquaculture and hydroponic ap-plications.SPECIFICATIONSpHORP Conductivity TemperatureRange 0.0 to 14.0 pH ±1000 mV 0 to 1999 μS/cm 0.0 to 60.0°CResolution 0.1 pH 1 mV 1 μS/cm 0.1°CAccuracy ±0.2 pH ±5 mV ±2% F.S. ±1°C(@20°C/68°F)Typical EMC ±0.4 pH ±2mV ±2% F.S. ±1°CDeviationCalibration manual factory manual factory2 point calibrated 1 point calibratedBattery Type/Life 3 x 1.5V / approx. 200 hours of continuous useEnvironment 0 to 50°C (32 to 122°F); RH max 95%Dimensions / Weight 190 x 85 x 85 mm (7.4 x 3.3 x 3.3") / 260 g (9.2 oz.)
