￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 5 Titrations 5 Titrations 5.1 Water determination according to Karl Fischer (KFT) Karl Fischer Titration is a method for volumetric water determination. Conditioning is carried out automatically both before and after the actual titration. The reagent dosing is controlled in such a way that a predefined endpoint is reached as quickly and as accurately as possible.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 6.1 Switching the instrument on and off 6 Operation 6.1 Switching the instrument on and off Switching on the instrument CAUTION Peripheral devices (e.g. printers) must be switched on before you switch on the 915 KF Ti-Touch. Proceed as follows: 1 ￭ ￭ ￭ Press the mains switch on the left-hand side of the rear panel of the 915 KF Ti-Touch. The 915 KF Ti-Touch is initialized. A system test is performed. This process takes some time.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 6 Operation Switching off the instrument CAUTION The 915 KF Ti-Touch must be switched off by pressing the mains switch on the rear of the instrument before the electricity supply is interrupted. If this is not done, then there is a danger of data loss. Proceed as follows: 1 ￭ Press the mains switch on the left-hand side of the rear panel of the 915 KF Ti-Touch. The current data is saved and the system is shut down. This process takes just a short time.
