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 connected to an MSB socket, along with a number of different cabling variations.

3.3.3 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 electrical
pulses (> 200 ms) which display the operating status 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.

plugged in.
The data of the dosing unit
cannot be read because
the data chip has been
damaged mechanically or
by chemicals.
The dosing drive is overloaded because the piston or
the valve disc is jammed.
Check the plug connections and switch on the
computer.
Have the data chip replaced by the Metrohm
Service. Until the data chip is being replaced
you can remove the data chip yourself in order
to be able to still use the dosing unit. The cylinder volume is automatically recognized nevertheless, but no data can be read from the
dosing unit or be saved on it anymore.
Exit tiamo™ and then restart it. The dosing
device will be initialized at this time. If the
error is not rectified by these actions, attempt
to remove the dosing drive.
If this is not possible, proceed as follows:
1. Exit tiamo™.
2. Press the locking button of the dosing unit
and remove the distributor. Turn it upside
down in its entirety.
3. Start tiamo™ and initiate 'Filling' in the
manual control. If the rotation of the stopcock is clearly audible, then the dosing
unit, with Dosino attached, can be reattached to the distributor.
4. Place the dosing unit with Dosino attached
upright on the distributor, align marking rib
to marking rib, and rotate the dosing unit
to the left until the spring clip snaps audibly
into place. Now you should be able to
remove the Dosino from the dosing unit.

6.1 Thermoprobes
6.1.1 Various models
The sensors for the 859 Titrotherm are called Thermoprobes. A Thermoprobe is a temperature sensor that is based on semiconductor technology
(thermistor). It has a short response time of 0.3 s and a high resolution of
10–5 K. This enables the precise recording of even the smallest of temperature changes that occur during a titration.
In contrast to potentiometric electrodes, Thermoprobes need not be calibrated!
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
Figure 13 Thermoprobes – two models
Thermoprobe with glass shaft
(6.9011.020)
For titrations in aqueous and nonaqueous
media. Not HF-resistant.
6.1.2 Cleaning and storage
The sensor can be cleaned by rinsing or brief immersion in a suitable solvent. Immerse all openings in the case of the 6.9011.020.
The sensor shaft can be carefully cleaned with a cloth.
￭￭￭￭￭￭￭￭

Thermoprobe with shaft made of PP
(6.9011.040)
For titrations in aqueous media. HF-resistant.
Can also be used in acidic solutions containing fluoride.

￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
Warning
The temperature sensor is very sensitive and can be considerably damaged by contact with fingers or objects.
Warning
The PTFE protective sleeve of the 6.9011.020 cannot and must not be
dismantled.
The sensor must always be stored in a dry place. After each sample series,
rinse the sensor with water or other cleaning solutions.
6.2 Maximum dosing and filling rate
The maximum dosing rate and maximum filling rate for the dosing unit
depend on the cylinder volume:
6 Appendix
Cylinder volume Maximum rate
2 mL 6.67 mL/min
5 mL 16.67 mL/min
10 mL 33.33 mL/min
20 mL 66.67 mL/min
50 mL 166.00 mL/min
Independent of the cylinder volume, values ranging from 0.01 to 166.00
mL/min can always be entered. When the function is carried out the rate
will be, if necessary, decreased automatically to the highest possible value.
