  • Page 12: Ph Measurements

    pH MEASUREMENT (for use with 840016, 840049 & 840051 optional probes) Calibration The pH probe should be calibrated before first use. Recalibrate regularly to ensure highly accurate measurement. Note… Calibration should begin with pH 7.00 and then be followed by either pH 4.00 or pH 10.00. Be sure to rinse the electrode in distilled water between calibration points.
  • Page 13 11. To clear the existing calibration data, select “CLr” from the calibration options. 12. Press ENTER to confirm the selection and return to Normal Mode. pH Probe Calibration with Manual Temperature Compensation 1. Plug and secure the pH probe into the pH socket on top of the meter.
  • Page 14 2. Plug the temperature probe into the TEMP socket on top of the meter. 3. Press POWER to turn the meter on. 4. Press FUNCTION to cycle through the available functions until “pH” is displayed. 5. Immerse the temperature probe into the solution to be measured.

  • Page 15: Do Measurements

    2. Press POWER to turn the meter on. 3. Press FUNCTION to cycle through the available functions until “OrP” is displayed. 4. Hold the electrode handle and immerse the sensing head completely into the solution to be measured. 5. Gently shake the electrode. 6.
  • Page 16 6. Press ENTER. The display will count down from 30 to 0 as calibration occurs. 7. The meter returns to Normal Mode. Do Measurement 1. Plug the DO probe (850081DO) into the DO socket on top of the meter. 2. Press POWER to turn the meter on. 3.

  • Page 17: Conductivity Measurements

    CONDUCTIVITY MEASUREMENT (for use with 850081C/TD or 850081C/SG optional probes) Conductivity Probe Calibration The conductivity probe should be calibrated before first use. Recalibrate the probe periodically to ensure accuracy. Note… One-point calibration should be executed at 1.413 mS. For multi-point calibration, execute 1.413 first and then proceed to other ranges.
