1.1 Warranty
The following instructions must be complied with in order for any
warranty to be applicable regarding functionality and safe opera-
tion of this equipment. This product must only be commissioned
by qualied professionals who are familiar with the legal require-
ments (Germany: DVGW).
●Read these operating instructions prior to operating the product.
●Use the product only as intended.
●Repairs and maintenance must only be carried out by special-
ist technicians or other suitably trained personnel. Only spare
parts approved by Hermann Sewerin GmbH may be used when
performing repairs.
●Use only suitable battery types, otherwise the device will not
be explosion-proof.
● Changes or modications to this product may only be carried
out with the approval of Hermann Sewerin GmbH.
●Use only Hermann Sewerin GmbH accessories for the product.
Hermann Sewerin GmbH shall not be liable for damages resulting
from the non-observance of this information. The warranty con-
ditions of the General Terms and Conditions (AGB) of Hermann
Sewerin GmbH are not affected by this information.
In addition to the warnings and other information in these Oper-
ating Instructions, always observe the generally applicable safety
and accident prevention regulations.
The manufacturer reserves the right to make technical changes.

1.2 Purpose
The Multitec 560 can be used as a gas measuring and gas
warning device.
The device is tted with infrared sensors for measuring hydro-
carbons CXHYand carbon dioxide CO2as standard. It can also
be equipped with electrochemical sensors for measuring O2, H2S
and CO.
The infrared sensors operate on the principle of absorption via
infrared-active gases, and the electrochemical sensors operate
on the electrochemical cell principle.
Multitec 560 as a gas warning device
As a warning device it is used to monitor the ambient air at the
workplace. The device can measure up to ve gases simultane-
ously, thus offering comprehensive protection against dangerous
gas concentrations. It provides warnings including:
●explosive gas concentrations
●lack of oxygen/excessive oxygen
●toxic gases
Multitec 560 as a gas measuring device
As a gas measuring device it determines the composition of gas
mixtures that are formed in biological processes (biogas, landll
gas). It measures the concentration of several gases in the gas
mixture simultaneously. The device is ideal for use in waste dis-
posal sites, sewage plants and biogas plants.
Note:
These operating instructions describe the Multitec 560 with all
additional equipment (rmware version 1.XXX). All descriptions
refer to the device as delivered (factory settings). The manufac-
turer reserves the right to make changes.

1.3 Intended use
This device is intended for professional residential and commer-
cial use including small rms and commercial operations. The
appropriate specialist knowledge is required to operate the device.
The device may only be used to measure the following gases
(depending on additional equipment):
●Methane CH4
●Carbon dioxide CO2
●Oxygen O2
●Hydrogen sulphide H2S
●Carbon monoxide CO
The device must not be used for:
●Gas analysis of technical processes
●Monitoring liquids
The device can be used up to a temperature of 40 ºC. However,
high temperatures reduce the lifetime of the sensors and re-
chargeable batteries.
If a device with an electrochemical sensor is exposed to gas
concentrations above the measuring range limit, this can reduce
the lifetime of the sensor.

1.4 General safety information
●The device has been tested to ensure that it is explosion-proof
in accordance with European standards (CENELEC).
●The work area must be well ventilated.
●The device must only be switched on with fresh air.
●In measuring mode, only change applications with fresh air.
●When switching from the Gas measuring application (using
the device as a gas measuring device) to the Warning ExTox
application (using as a gas warning device), the device should
only be used as a gas warning device once the zero points
have appeared.
●Do not use this device in oxygen-enriched atmospheres, oth-
erwise it will not be explosion-proof.
●Observe the relevant safety regulations when working at agri-
cultural biogas plants.
● Only probe hoses with a hydrophobic lter may be used.
Exception:
If the probe has a built-in hydrophobic lter, the hose does not
require any other lters.
●The device must only be tested and adjusted with test gases
in well ventilated rooms or in the open air. Test gases must be
handled in a professional manner.
●Always carry out a device inspection after the device has suf-
fered an impact (for example, if dropped accidentally).
●The device complies with the limits of the EMC directive. Always
observe the information in the manuals of (mobile) radio equip-
ment when using the device close to (mobile) radio equipment.
Note:
Follow the advice regarding explosion protection (see Section. 2.3
on page 7).

2 Features
2.1 Visual and audible signals
The device features two alarms:
● Signal light on top of device (visual signal)
● Buzzer on side of device (audible signal)
The signals indicate alarms and faults (see Section. 6 on
page 49). The device also emits signals when it is switched
on and off.
If this symbol appears on the display, the audible signal
can be switched off.
When an audible signal has been switched off it cannot
be switched back on.
This symbol appears at the top left of the display as soon
as the audible signal has been switched off. It disappears
automatically if the level falls below the alarm threshold.
Operating signal
Only applies to Warning ExTox application.
The device emits a visual signal and an audible signal at regular
intervals. This indicates that the device is working properly.
Alarm
Only applies to Warning ExTox application.
The device can monitor several gases at the same time. If the
measured gas concentration of one or more gases exceeds spec-
ied limit values (alarm thresholds) the device gives a warning. It
emits both audible and visual signals, which are distinctly different
from the operating signal.

●Take all necessary measures for your own safety and
the safety of others immediately.
There is detailed information on alarms in Section. 7.2 on
page 51.

ing ExTox application), it must be regularly inspected
before use.
●Carry out a device inspection every day before starting
work.
Note:
You may only switch applications when the device is drawing in
fresh air.
The current application is indicated by the symbol at the top left
of the display. The symbol at the bottom right shows the next ap-
plication that can be selected via function key F3. The Settings
under System (see Section 3.3.4) are used to specify which ap-
plication is rst activated when you switch the device on.
●Press Menu. Select the menu item for the application you
want to use.
OR
a) Press function key F3. The device switches to the next ap-
plication.
b) Repeat until the symbol for the application you want to use
appears at the top left.
3.1.5 Differences between measuring mode and settings mode
The device is operated in two modes:
●Measuring mode (see Section. 3.2 on page 14)
Measurements are taken in measuring mode. All functions
