Generally applicable safety and accident-prevention regulations
must be complied with, in addition to the information provided in
this manual.

1.2 Purpose
The Multitec 540 is a gas measuring device for monitoring gas
mixtures that are formed in biological processes (biogas, landll
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.
The Multitec 540 is tted with infrared sensors for measuring

and carbon dioxide CO2 as standard. It can also

Note:
These operating instructions refer to the Multitec 540
with all additional equipment. They explain the functions of rmware version 1.XXX. The manufac-
turer reserves the right to make technical changes.
All descriptions refer to the device as delivered (factory settings).

1.3 Intended use
This device is intended for professional residential and commercial
use including small rms and commercial operations. The appro-
priate specialist knowledge is required to operate the device.
The device may be used to measure the following gases (depending on the sensors tted).
z Methane CH
z Carbon dioxide CO
z Oxygen O
z Hydrogen sulphide H2S
If the device is used in closed spaces these must be well ventilated.
It should not be used for:
z Warning of dangerous gas concentrations
z Monitoring liquids
The device can be used up to a temperature of 40 ºC. However,
high temperatures reduce the lifetime of the sensors and rechargeable batteries.
If a device with an electrochemical sensor is exposed to concentrations above the measuring range limit, this can reduce the
lifetime of the sensor.

1.4 General safety information
z The Multitec 540 is a gas measuring device as opposed to a
gas warning instrument. It does not, therefore, warn of dangerous toxic and explosive gas concentrations or lack of oxygen. If
you suspect dangerous gas concentrations, always take along
a gas warning instrument too.
z Observe the relevant safety regulations when working at agri-
cultural biogas plants/1/.
z The work area must be well ventilated.
z The device has been tested to ensure that it is explosion-proof
in accordance with European standards (CENELEC).
z Do not use this device in oxygen-enriched atmospheres, oth-
erwise it will not be explosion-proof.
z 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.
z Devices may only be tested with test gases in well ventilated
areas or outdoors. Test gases must be handled in a profes-
sional manner.
z Always carry out a device inspection (see Section 5.1) after
the device has suffered an impact (for example, if dropped
accidentally).
z The device complies with the limits of the EMC directive. Al-
ways observe the information in the manuals of (mobile) radio equipment when using the device close to (mobile) radio
equipment.
CAUTION!
Follow the advice regarding explosion protection
(see Section 2.3).

2 Features
2.1 Visual and audible signals
The device features two alarms:
z Signal light on top of device
(visual signal)
z Buzzer on side of device (audible signal)
The signals indicate faults (see Section 6). The device also emits
signals when it is switched on and off.
2.2 Sensors
The device features two types of sensor:
z Infrared sensor (IR)
z Electrochemical sensor (EC)

WARNING!
It is essential to observe the following points to en-
sure that the device is explosion-proof:
– Always open the battery compartment and re-
charge the batteries outside the explosive area.
– Always use the USB port outside the explosive
area.
– Always use the appropriate type of disposable/
rechargeable battery.
– To ensure that the device complies with explo-
