OPERATIONAL GUIDE PRELIMINARY OPERATIONS TAKING RESISTIVITY MEASUREMENTS • Plug the supplied 12 Vdc adapter into the power supply socket on the rear panel. Note: Make sure the main line is protected by a fuse. • Connect the desired probe (HI 76303 for conductivity or HI 3316D for resistivity measurements) to the DIN socket on the rear panel. The instrument will automatically recognize which probe is connected.
CALIBRATION CONDUCTIVITY VS. TEMPERATURE CHART °C CONDUCTIVITY CALIBRATION • It is recommended to calibrate the instrument for the conductivity range at least once a month, or when the probe is changed. • For better accuracy, choose a solution with a conductivity value close to the sample to be measured. If you are measuring in the mS ranges, calibrate the meter using the HI 7030 (12.88 mS/cm @25°C) or HI 7034 (80 mS/cm @25°C) conductivity solution.
DETERMINATION OF THE TEMPERATURE COEFFICIENT OF A SOLUTION • Immerse the probe into a sample of the solution and adjust the conductivity TC knob to 0% (i.e. no compensation). • Condition sample and probe at 25°C, and note the conductivity reading C25. • Condition sample and probe to a temperature T, approximately 5°C to 10°C different from 25°C, and note the conductivity reading CT.
