[. . . ] Instruction Manual CON 6/TDS 6 Hand-held Conductivity/TDS Meter 68X243618 Technology Made Easy . . . Rev. 2 01/04 Preface This manual serves to explain the use of the Conductivity and TDS handheld meters. The models covered are the CON 6 and TDS 6. This manual functions in two ways: first as a step by step guide to help you operate the meter; second, it serves as a handy reference guide. This manual is written to cover as many anticipated applications of the Conductivity and TDS handheld meters as possible. [. . . ] The five ranges are: Conductivity Range (CON 6) 0 ­ 20. 00 µS/cm 0 ­ 200. 0 µS/cm 0 ­ 2000 µS/cm 0 ­ 20. 00 mS/cm 0 ­ 200. 0 mS/cm TDS Range (TDS 6) (if TDS factor is 0. 5) 0 ­ 10. 00 ppm 0 ­ 100. 0 ppm 0 ­ 1000 ppm 0 ­ 10. 00 ppt 0 ­ 100 ppt 22 Instruction Manual CON 6/TDS 6 Auto-ranging Manual ranging: 0 - 20. 00 uS/cm Manual ranging: 0 - 200. 0 uS/cm µS µS µS mS mS µS Manual ranging: 0 - 200. 0 mS/cm Manual ranging: 0 - 20. 00 mS/cm Manual ranging: 0 - 2000 uS/cm NOTE: If the value of the solution you are measuring is higher than the range selected [Or] will appear on the primary display. Press RANGE until the correct range is selected. The meter resets to the Auto-ranging function once it is turned off. You will have reset the manual ranging function each time you turn the meter off. 23 Instruction Manual CON 6/TDS 6 5. 5 HOLD Function This feature lets you freeze the display for a delayed observation. HOLD can be used any time in measurement mode. 1) To hold a measurement, press the HOLD key while in measurement mode. To release the held value, press the HOLD again. Continue to take measurements. HOLD ENTER µS HO 2) µS NOTE: This meter shuts off automatically after 20 minutes of nonuse. If the meter is shut off either automatically or manually, the HOLD value will be lost. 24 Instruction Manual CON 6/TDS 6 6 6. 1 ADVANCED SETUP FUNCTIONS Advanced Setup Overview The advanced setup mode lets you customize your meter's preferences and defaults. To enter advanced setup mode: 1) 2) 3) 4) Make sure that the meter is switched-off. Press ON and MODE key simultaneously, holding both keys for 2 seconds. First release ON key first before releasing the MODE key. [StUP] indicator will appear momentarily and [CELC] will appear next. Overviews of CON 6 and TDS 6's Setup Menu as follows. Enter Setup Page. Select Cell Constant. "Yes" for auto calibration and "no" for manual calibration. (Available in CON 6 meter only) % Adjust Temperature Coefficient value from 0. 0 to 3. 0 %/°C. Default value is 2. 1 %/°C. 25 Instruction Manual °C CON 6/TDS 6 Select Normalization Temperature. Choice of either 20 °C or 25 °C. (Available in TDS 6 meter only) Select Single Point Calibration. Choice of "Yes" or "No". Choice of "Yes" or "No". Default value is "no". Overview of Advanced Setup 26 Instruction Manual CON 6/TDS 6 Meter Off ON OFF MODE Press ON/OFF and MODE keys simultaneously for 2 seconds, release ON/OFF key first then release MODE key a second later. [. . . ] If you make measurements at extreme temperatures, calibrate the meter at least once a week. You should only use the conductivity / TDS probe specified for these meters. These probes have a built-in temperature sensor. If you use a different probe without a temperature sensor, you must measure the solution temperature separately and manually enter the solution temperature (see manual temperature compensation section 5. 2) 45 Instruction Manual CON 6/TDS 6 14 ADDENDUM 2: CALCULATING TDS CONVERSION FACTOR You can calibrate your meter using TDS calibration standard solutions. The calibration standard only needs to give the TDS value at a standard temperature such as 25 °C. [. . . ]
