If the height of the KF titration cell has been adjusted correctly, the entire cell can be raised and swiveled as required by pressing the locking lever. ■■■■■■■■ 915 KF Ti-Touch...
Connecting MSB devices In order to connect MSB devices, e.g. dosing devices or Remote Box, the Ti-Touch has two connectors to what is referred to as the Metrohm Serial Bus (MSB). Various peripheral devices can be connected in sequence (daisy chain) at a single MSB connector (8-pin Mini DIN socket) and be control- led simultaneously by the Ti-Touch.
6 m. 5.4.1 Connecting a dosing device You can connect two dosing devices to the Ti-Touch. The types of dosing devices that are supported are: 800 Dosino ■ 805 Dosimat ■ ■■■■■■■■ 915 KF Ti-Touch...
Instruments that are controlled via remote lines and/or that send control signals via remote lines can be connected via the 6.2148.010 Remote Box. In addition to Metrohm, other instrument manufacturers also use similar connectors that make it possible to connect different instruments together.
5.5.1 General The 915 KF Ti-Touch has a USB connector (Type A socket) for peripheral devices with USB interface and for Sample Processors. If you wish to con- nect more than one device to the USB, you can use a commercially avail- able USB hub.

Connect the PC keyboard as follows: 1 Connect the USB plug of the keyboard with the USB connector of the Ti-Touch (Type A). 2 Enter and configure the keyboard in the device manager of the Ti-Touch. ■■■■■■■■ 915 KF Ti-Touch...
If you wish to integrate your Ti-Touch in an automation system, then you can connect the following Sample Processors to the USB connector: 814 USB Sample Processor ■ 815 Robotic USB Sample Processor XL ■ 810 Sample Processor (from firmware version 5.915.0040) ■ ■■■■■■■■ 915 KF Ti-Touch...
3 Configure the Sample Processor in the device manager. Setting up the titration vessel The tutorial for the 915 KF Ti-Touch includes a detailed description of how to set up the Karl Fischer titration cell and what needs to be taken into account while doing so.
Connecting the temperature sensor A temperature sensor of the Pt1000 or NTC type can be connected to the Temp. connector. Connect the temperature sensor as follows: 1 Plug the temperature sensor plugs into the Temp. sockets of the Ti-Touch. ■■■■■■■■ 915 KF Ti-Touch...
Connecting the Ti-Touch to a network The 915 KF Ti-Touch has a network connection (Ethernet). This can be used to integrate your Ti-Touch in your network. You can, for example, store data on a PC within the network or print reports on a network printer.
