PAGE 60
Operation QSC calibration HandyLab 680 The QSC function is enabled by once carrying out an additional threepoint calibration with special QSC buffer solutions. It covers the measuring range of the sensor from pH 2 to pH 11. The QSC initial calibration determines the actual condition of the sensor and stores it as a reference in the sensor. To meet the high requirements of a QSC initial calibration, the QSC initial calibration should optimally be carried out with the initial commissioning of the sensor.
PAGE 61
HandyLab 680 Operation 4 As soon as the three-point calibration has been successfully carried out you can decide whether to accept or discard the calibration as the QSC initial calibration. The QSC initial calibration is completed. The sensor is calibrated. If you want to calibrate with special buffers for your measurements, you can subsequently carry out a normal calibration with your buffers.

HandyLab 680 Operation 4.9.4 FDO® Check procedure (check of the FDO® 1100 IDS) Why should you check the sensor? When should you check the sensor? With the FDO® Check procedure, you can find out in a simple manner whether the FDO® 1100 IDS D.O. sensor should be cleaned or calibrated.

HandyLab 680 Operation 4.9.5 D.O. calibration Why calibrate? D.O. sensors age. This changes the slope of the D.O. sensor. Calibration determines the current slope of the sensor and stores this value in the instrument. Note The FDO® 1100 IDS D.O. sensor ages so little it does not have to be regularly calibrated. To detect changes of the sensor as early as possible, the FDO® Check procedure can be useful (see section 4.9.4).

Operation HandyLab 680 4.10.5 Determining the cell constant (calibration in control standard) Why determine the cell constant? Aging slightly changes the cell constant, e. g. due to coatings. As a result, an inexact measured value is displayed. The original characteristics of the cell can often be restored by cleaning the cell. Calibration determines the current value of the cell constant and stores this value in the meter. Thus, you should calibrate at regular intervals (we recommend: every 6 months).
