1 Introduction

1.1 Instrument description

The 915 KF Ti-Touch is a compact titration system for volumetric Karl Fischer titration. This newly designed titrator combines in a single device the touch-sensitive color monitor for convenient and efficient operation, the titration unit, the magnetic stirrer and the integrated membrane pump for adding and aspirating solvents. The upper side of the housing offers space for the titrant and the titration cell. The titrator is standard-equip­ped for operation with an external dosing drive of the 800 Dosino type with a dosing unit. You can however also use a 805 Dosimat with an exchange unit. Thanks to its compact construction, you can use the 915 KF Ti-Touch in a small space as a stand-alone titrator.
You manage titrants, sensors, methods, etc. conveniently in the internal memory of the 915 KF Ti-Touch. You can also save your files externally through the USB connector, e.g. on a USB flash drive. On this storage medium you can not only store your methods and determinations, but also create a backup together with all of the data and settings of your sys­tem.

4.3.3 Connecting a Remote Box

Instruments that are controlled via remote lines and/or which send control signals via remote lines can be connected using 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. These interfaces are also frequently given the designations "TTL Logic", "I/O Control" or "Relay Control" and generally have a signal level of 5 volts.
Control signals are understood to be electrical line statuses or brief (> 200 ms) electrical pulses which display the operational state of an instrument or which trigger or report an event. Sequences on a variety of instruments can thus be coordinated in a single complex automation sys­tem. No exchange of data is possible, however.
Proceed as follows:

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. The volume steps and the rate of reagent dosing are regulated by the difference between the current measured value and the predefined endpoint. This means that titration is performed more slowly in the control range and that smaller volumes are added. The titration is stopped at the endpoint either drift-controlled or after a waiting time. The volume dosed until the endpoint is used to calculate the water content of the sample.

7.3.2 Creating an identification profile

User list: User ▶ Create ID profile
If you plan to carry out the login with an identification profile (see Chapter
7.3.3, page 41), then you must first create an identification profile on a storage medium for each user. A check can then be made at the time of login as to whether or not the user does exist and whether or not he or she is working in the expert dialog or in the routine dialog. After a suc­cessful login the routine dialog settings stored on the card are loaded.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
NOTE
In addition to the user name, the current routine dialog settings are also stored in this identification profile. This means you can define user­specific routine dialog settings for each user. However, you must con­figure them (see "Configuring the routine dialog", page 35), before you create the identification profile.
Before you create the identification profile, check whether the desired routine dialog settings are active.

8 Titrants

￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
Main dialog: System ▶ Titrants
This chapter describes how you can create a list of titrants used in the sys­tem. Titrants can be used in intelligent buret units or in non-intelligent buret units. Intelligent buret units have a built-in data chip on which the data for the titrant is stored. This data is automatically read out during attachment and entered in the titrant list.
The titrant list can contain a maximum of 30 titrants. The following data is specified for each titrant:
￭ Designation ￭ Cylinder volume ￭ Type
– IDU: dosing unit with integrated data chip – IEU: exchange unit with integrated data chip – EU: exchange unit without data chip
￭ MSB connector of the dosing device/control device (only when
exchange unit/dosing unit is attached)
Titrants in exchange units/dosing units with integrated data chips are depicted in green lettering.
The following titrant data is stored in the titrant list:
￭ Name
Each titrant in the system is identified by its unambiguous name.
￭ Current titer ￭ Working life

NOTE
If data is read out from the data chip, then a check is made whether the titrant list already contains a titrant of the same type with the iden­tical serial number. If this is the case, then the older data set will always be overwritten by the new data set, no matter whether the data set in the titrant list or the data set on the data chip is the most recent one.
Add a new titrant to the list (see Chapter 8.1, page 47).
