Page 2: Meter Overview
Overview Connectors Introduction Thank you for selecting the DDS-12DW benchtop conductivity meter. This user manual provides a step-by-step guide to help you operate the meter, please carefully read the following instructions before use. Any use outside of these instructions may invalidate your warranty and cause permanent damage to the meter. -
Page 3: Installing The Electrode Holder
Overview Remove the plastic cover from the right side of the electrode Function arm. • Switch the meter on or off • Lock or unlock the measurement • Exit the calibration, settings and return to the measurement mode Start calibration Use the screwdriver to tighten the screw moderately. -
Page 4: Switching The Meter On And Off
Overview Connecting the Temperature Probe 2.1 Place the temperature probe into the circular hole located at the Switching the Meter On and Off center of the electrode arm. • Press the Meas key for about 3 seconds and release to switch on the meter. - Page 5 Setup Measurement Unit Temperature Compensation Set the default temperature unit. The temperature compensation has a large effect on the conductivity Degrees Celsius (default) measurement. If enabled, the meter will use the measured conductivity Degrees Fahrenheit and temperature readings to calculate the results and automatically compensate to the selected reference temperature.

Measurement Wait for the measurement to stabilize and record the reading. When all of the samples have been measured, rinse the electrode Temperature Calibration with distilled water. The meter is supplied with a temperature probe for measurement and temperature compensation. If the measured temperature reading If the meter shows ---- indicating the measurement exceeds the range, differs from that of an accurate thermometer, the probe needs to be replace a conductivity electrode that is appropriate for the conductivity... - Page 8 Appendix Where: = Temperature coefficient Appendix = Conductivity at temperature A = Conductivity at temperature B = Temperature A Preparation of Conductivity Standard Solutions = Temperature B Place the analytical grade potassium chloride (KCl) in a beaker and dry in an oven for about 3 hours at 105° C (221° F), then cool Optional Accessories to room temperature.
