2 Introduction
2.1 Instrument description
The 916 Ti-Touch is a compact titration system for volumetric titration.This newly designed titrator combines in a single device the touch-sensi-tive color monitor for convenient and efficient operation, the titration unitand an integrated stirrer interface for a propeller stirrer. The upper side ofthe housing offers space for the titrant and the titration vessel. The titratoris standard-equipped for operation with an external dosing drive of the800 Dosino type with a dosing unit. You can however also use a 805 Dos-imat with an exchange unit. Thanks to its compact construction, you canuse the 916 Ti-Touch in a small space as a stand-alone titrator.
You manage titrants, sensors, methods, etc. conveniently in the internalmemory of the 916 Ti-Touch. You can also save your files externallythrough the USB connector, e.g. on a USB flash drive. On this storagemedium you can not only store your methods and determinations, butalso create a backup together with all of the data and settings of your sys-tem.
The integrated Ethernet connection is available to you should you wish toconnect your 916 Ti-Touch to a network. The network connection offersyou the following advantages:
￭ Saving data to a PC within the network￭ Printing reports on a network printer￭ Sending displayed messages as e-mails
2.1.1 Titration and measuring modesThe 916 Ti-Touch supports the following titration and measuring modes.
￭ DETDynamic equivalence point titration. The reagent is added in variablevolume steps.Measuring modes:

5.4 Connecting MSB devices
In order to connect MSB devices, e.g. dosing device or Remote-Box, theTi-Touch has two connectors at what is referred to as the Metrohm SerialBus (MSB). Various peripheral devices can be connected in sequence (daisychain) at a single MSB connector (8-pin Mini DIN socket) and be control-led simultaneously by the Ti-Touch. In addition to the connection cable,stirrers and the Remote Box are each equipped with their own MSB socketfor this purpose.
The following figure provides an overview of the devices that can be con-nected to an MSB socket, along with a number of different cabling varia-tions.

Note
When connecting MSB devices together, the following must beobserved:
￭ Only one device of the same type can be used at a single MSB con-nector at one time.
￭ When making the connection, take care to ensure that the flat partof the MSB plug marked with arrows is pointing in the direction ofthe marking on the MSB connector (see Figure 6, page 15).

Caution
Switch off the Ti-Touch before you plug in MSB devices. When it isswitched on, the Ti-Touch automatically recognizes which device is con-nected to which MSB connector. The connected MSB devices areentered automatically in the device manager.
MSB connections can be extended with the 6.2151.010 cable. The maxi-mum connection length permitted is 6 m.
5.4.1 Connecting dosing devicesYou can connect two dosing devices to the Ti-Touch.
The types of dosing devices that are supported are:
￭ 800 Dosino￭ 805 Dosimat
Proceed as follows:
1 Switch off the Ti-Touch.
2 Connect the dosing device connection cable to an MSB connector(2-7) on the rear side of the Ti-Touch.

5.4.2 Connecting an additional stirrer or titration standIn addition to the built-in stirrer connector for the propeller stirrer 802 Stir-rer, you can use the magnetic stirrers 801 Stirrer, 803 Ti Stand or the 804Ti Stand with the propeller stirrer 802 Stirrer.
Proceed as follows:
1 Switch off the Ti-Touch.
2 Connect the connection cable of the magnetic stirrer or of the titra-tion stand to MSB 2 (2-7) on the rear of the Ti-Touch.
3 Connect the propeller stirrer, if desired, to the stirrer connector ofthe titration stand.
4 Switch on the Ti-Touch.
5.4.3 Connecting a Remote BoxInstruments that are controlled via remote lines and/or which send controlsignals via remote lines can be connected using the 6.2148.010 RemoteBox. In addition to Metrohm, other instrument manufacturers also usesimilar connectors that make it possible to connect different instrumentstogether. These interfaces are also frequently given the designations "TTLLogic", "I/O Control" or "Relay Control" and generally have a signal levelof 5 volts.
Control signals are understood to be electrical line statuses or brief(> 200 ms) electrical pulses which display the operational state of aninstrument or which trigger or report an event. Sequences on a variety ofinstruments can thus be coordinated in a single complex automation sys-tem. No exchange of data is possible, however.
Proceed as follows:
1 Switch off the Ti-Touch.
2 Connect the Remote Box connection cable to an MSB connector(2-7) on the rear side of the Ti-Touch.
3 Switch on the Ti-Touch.
You can connect an 869 Compact Sample Changer. The Remote Box alsohas an MSB socket at which a further MSB device, e.g. a dosing device,can be connected.

The iConnect is detected automatically and entered as measuringinput into the device properties of the Ti-Touch. If an electrode isconnected to the iConnect that is not yet included in the list of sen-sors for the Ti-Touch, then a corresponding message will be dis-played.
The iConnect can be plugged in and unplugged while the Ti-Touch isswitched on.
An electrode with integrated data chip, referred to as iTrode, is connectedto the iConnect.
Connect the electrode as follows:
1 Remove the protective caps on the iConnect and the electrode.
2 Plug in the electrode on the iConnect as illustrated in Fig. 12, page25.

5.6.7 Differential potentiometryPotentiometric measurements with high-ohm measuring chains can bedisrupted by electrostatic and electromagnetic fields in media with lowconductivity. Use our 6.0229.100 Solvotrode or other special electrodesfor pH measurements in organic solvents. If no reliable measurements arepossible with these, then a 6.5104.030 (230 V) or 6.5104.040 (115 V) dif-ferential amplifier can be used. The differential amplifier is connected tothe high-ohm measuring input (Ind.).
5.7 Connecting the Ti-Touch to a network
The 916 Ti-Touch has a network connection (Ethernet). This can be usedto integrate your Ti-Touch in your network. You can, for example, storedata on a PC within the network or print reports on a network printer.You will find information as to which settings are necessary for the net-work connection in the Device manager chapter contained in the moredetailed manual.

The steps involved in the design, manufacture and servicing of instrumentsare fully documented and the resulting reports are archived for ten years.The development of software for PCs and instruments is also duly docu-mented and the documents and source codes are archived. Both remainthe possession of Metrohm. A non-disclosure agreement may be asked tobe provided by those requiring access to them.
The implementation of the ISO 9001:2000 quality management system isdescribed in Metrohm’s QM Manual, which comprises detailed instruc-tions on the following fields of activity:
Instrument development
The organization of the instrument design, its planning and the intermedi-ate controls are fully documented and traceable. Laboratory testingaccompanies all phases of instrument development.
Software development
Software development occurs in terms of the software life cycle. Tests areperformed to detect programming errors and to assess the program’sfunctionality in a laboratory environment.
Components
All components used in the Metrohm instruments have to satisfy the qual-ity standards that are defined and implemented for our products. Suppli-ers of components are audited by Metrohm as the need arises.
Manufacture
The measures put into practice in the production of our instruments guar-antee a constant quality standard. Production planning and manufacturingprocedures, maintenance of production means and testing of compo-nents, intermediate and finished products are prescribed.

Customer support and service
Customer support involves all phases of instrument acquisition and use bythe customer, i.e. consulting to define the adequate equipment for theanalytical problem at hand, delivery of the equipment, user manuals, train-ing, after-sales service and processing of customer complaints. TheMetrohm service organization is equipped to support customers in imple-menting standards such as GLP, GMP, ISO 900X, in performing Opera-tional Qualification and Performance Verification of the system compo-nents or in carrying out the System Validation for the quantitative determi-nation of a substance in a given matrix.
7.3 Warranty (guarantee)
Metrohm guarantees that the deliveries and services it provides are freefrom material, design or manufacturing errors. The warranty period is 36months from the day of delivery; for day and night operation it is 18months.
