It evaluates the condition of an IDS pH sensor individually and with a very fine grading. On the display, the QSC color scale (from green to yellow) indicates the current sensor evaluation by means of a pointer.
  • Page 57 Multi 3410 Operation QSC calibration The QSC function is enabled by once carrying out an additional three- point calibration with special QSC buffer solutions. It covers the mea- suring range of the sensor from pH 2 to pH 11. The QSC initial calibra- tion determines the actual condition of the sensor and stores it as a reference in the sensor.
