↑↓=Buttons for browsing between the selected modes, for entering a value or for selecting a function.
OK=Proceeds a function.
CAL=Starts a calibration.
STORE=Stores the displayed value or send it to a computer or printer.

Inputs

The measuring electrodes should be connected to the coaxial input. Automatic temperature compensation and measurement are possible by connecting a Pt1000 temperature compensator to the banana connectors °C. Without compensator, the manual temperature compensation is automatically switched on.

  3. After rinsing the electrode several times with the first standard solution, immerse it in that standard. The solution temperature is not so critical but should lie between 0°C and 40°C. When no Pt1000 is used, do not forget to compensate manually first! Select [CALIBRATE], press OK and follow the instructions on the screen until the calibration is finished.
  4. Rinse the electrode several times with the sample, immerse it in that solution and read the display.
  5. Rinse the electrode always after use and store it in distilled water (add some detergent to keep the spongy platinum surface in perfect condition).

A blinking decimal point warns you for unstable measurements. Wait to read the display!

  • Stirring the solution during the measurements promotes the homogeneity and is obligatory!
  • The instrument will refuse automatic calibration when the electrode is unstable. Insufficient stirring or a worn electrode may be the cause.
  • When starting a titration, hold MODE pressed and press ê to lock the actual range and avoid cross-over errors due to differences in the measuring frequency. Hold MODE pressed and press ê to return again to the normal measuring mode.

Temperature compensation

  1. Press CAL.
  2. Select [REF.] and press OK.
  3. Select the temperature to which all future measurements will be referred to (25°C or 20°C) and press OK.
