1 Introduction
The 859 Titrotherm is a Metrohm titrator for thermometric titration. Ther-
mometric titration can be utilized where potentiometric indication is either
not possible or possible only to a limited extent.
For the theory and application possibilities of thermometric titration, we
recommend the monograph: Thomas Smith, Practical thermometric
titrimetry, Metrohm AG, 2006 (Order No. 8.036.5003).
1.1 The 859 Titrotherm in the Titrando system
The 859 Titrotherm is a component of the modular Titrando system. Oper-
ation is carried out with a computer containing the software tiamo™
(starting with Version 2.2).
A Titrando system can contain numerous, various kinds of instruments.
The following figure provides an overview of the peripheral devices you
can connect to the 859 Titrotherm.

1.2.2 Intended use
The 859 Titrotherm is designed for usage as a titrator in analytical labora-
tories. Its main area of application is the determination of ions in aqueous
and nonaqueous media. The 859 Titrotherm uses the method of thermo-
metric titration.
This instrument is suitable for processing chemicals and flammable sam-
ples. The usage of the 859 Titrotherm therefore requires that the user has
basic knowledge and experience in the handling of toxic and caustic sub-

3 Installation
3.1 Setting up the instrument
3.1.1 Packaging
The instrument is supplied in protective packaging together with the sepa-
rately packed accessories. Keep this packaging, as only this ensures safe
transportation of the instrument.
3.1.2 Checks
Immediately after receipt, check whether the shipment has arrived com-
plete and without damage by comparing it with the delivery note.
3.1.3 Location
The instrument has been developed for operation indoors and may not be
used in explosive environments.
Place the instrument in a location of the laboratory which is suitable for
operation and free of vibrations and which provides protection against
corrosive atmosphere and contamination by chemicals.
The instrument should be protected against excessive temperature fluctua-
tions and direct sunlight.
3.2 Connecting the instrument to the power grid
WARNING
Electric shock from electrical potential
Risk of injury by touching live components or through moisture on live
parts.
￭Never open the housing of the instrument while the power cord is
still connected.
￭Protect live parts (e.g. power supply unit, power cord, connection
sockets) against moisture.
￭Unplug the power plug immediately if you suspect that moisture has
gotten inside the instrument.
￭Only personnel who have been issued Metrohm qualifications may
perform service and repair work on electrical and electronic parts.

1Plugging in the power cord
￭Plug the power cord into the instrument's power socket.
￭Connect the power cord to the power grid.
3.3 Connecting a computer
The 859 Titrotherm requires a USB connection to a computer in order to
be able to be controlled by a computer software. Using a 6.2151.000
controller cable, the instrument can be connected directly, either to a USB
socket on a computer, to a connected USB hub or to a different Metrohm
control instrument.
You need administrator rights for the installation of driver software and
control software on your computer.
Cable connection and driver installation
A driver installation is required in order to ensure that the 859 Titrotherm
is recognized by the computer software. To accomplish this, you must
comply with the procedures specified. The following steps are necessary:
1Installing the software
￭Insert the computer software installation CD and carry out the
installation program directions.
￭Exit the program if you have started it after the installation.

￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 3 Installation

2Establishing the cable connections
￭Connect the instrument to the power supply if you have not
already done this.
The "On" LED on the 859 Titrotherm is not yet illuminated!
￭Connect the instrument to a USB connector (type A) of your com-
puter (see manual of your computer). The 6.2151.000 cable is
used for this purpose.
6.2151.000
Figure 5 Connecting the computer
The instrument is recognized. Depending on the version of the Win-
dows operating system used, the driver installation proceeds differ-
ently afterwards. Either the necessary driver software is installed
automatically or an installation wizard is started.
3Follow the instructions of the installation wizard.
The "On" LED on the 859 Titrotherm lights up when the driver instal-
lation has been completed and the instrument is ready for operation.
If problems should occur during installation, contact your company's IT
support team.
NOTICE
The plug on the instrument end of the 6.2151.000 controller cable is
protected against accidental disconnection by means of a pull-out pro-
tection feature. If you wish to pull out the plug, you first need to pull
back the outer plug sleeve marked with arrows.

3.4 Connecting MSB devices ￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
12 ￭￭￭￭￭￭￭￭ 859 Titrotherm
Registering and configuring the instrument in the computer
software
The instrument must be registered in the configuration of your computer
software. Once that has been done, you can then configure it according
to your requirements. Proceed as follows:
1Setting up the instrument
￭Start the computer software.
The instrument is automatically recognized. The configuration dia-
log for the instrument is displayed.
￭Make configuration settings for the instrument and its connectors.
More detailed information concerning the configuration of the
instrument can be found in the documentation for the respective
computer software.
3.4 Connecting MSB devices
In order to connect MSB devices, e.g. stirrers or dosing devices, Metrohm
instruments are equipped with up to four connectors on what is referred
to as the Metrohm Serial Bus (MSB). Various kinds of peripheral devices
can be connected in sequence (in series, as a «daisy chain») at a single
MSB connector (8-pin Mini DIN socket) and controlled simultaneously by
the respective control device. In addition to the connection cable, stirrers
and the Remote Box are each equipped with their own MSB socket for
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.
