FUNCTIONAL DESCRIPTION OF HI 76302W CONDUCTIVITY PROBE OPERATIONAL GUIDE INITIAL PREPARATION 1 Each meter is supplied complete with a 9 V battery. Remove the back cover, unwrap the battery and install it while paying attention to its polarity its (see "Battery Replacement" section). 3 4 2 1) 2) 3) 4) Watertight screened cable (1 m / 3.
TEMPERATURE EFFECT HI 76302W conductivity probe features a built-in temperature sensor that allows automatic compensation of the reading for any temperature differences. Wait for a few minutes for the temperature sensor to reach the thermal equilibrium with the test solution before taking measurements. If the temperature of conductivity probe and solution is drastically different, a longer time should be allowed.
• When the reading is stable, adjust the calibration trimmer to read the solution conductivity value @25°C. For example if using HI 7030, turn the trimmer to read 12.88 mS/cm @ 25°C. mS The calibration is now complete and the instrument is ready for use. All subsequent measurements will be compensated to 25°C (77°F). Note: Calibration can also be standardized to have readings compensated to 20°C (68°F), by simply adjusting the trimmer to the calibration solution value at 20°C (68°F).
CONDUCTIVITY VS. TEMPERATURE TDS VS. TEMPERATURE The conductivity of an aqueous solution is the measure of its ability to carry an electrical current by means of ionic motion. The conductivity increases with increasing temperature. In fact, it is affected by the type and number of ions in the solution, and by the viscosity of the solution itself. Both parameters are temperature dependent.
PROBE MAINTENANCE After evry series of measurements, rinse the probe with tap water. If a more thorough cleaning is required, remove the PVC sleeve and clean the probe with a cloth or a nonabrasive detergent. When reinserting the sleeve onto the probe, be sure that the sleeve is in the right direction with the four holes towards the cable end. After cleaning the probe, always re-calibrate the instrument. The probe body is made of PVC. For this reason it must never come into close contact with a heat source.

CE DECLARATION OF CONFORMITY Recommendations for Users Before using these products, make sure that 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. The metal band at the end of the probe is sensitive to electrostatic discharges. Avoid touching this metal band at all times.
