1.3
Intended use
This device is intended for professional residential and commercial
use including small firms and commercial operations. The appropriate specialist knowledge is required to operate the device.
The device may be used to measure the following gases (depending on the sensors fitted).
zzMethane CH4
zzCarbon dioxide CO2
zzOxygen O2
zzHydrogen sulphide H2S
If the device is used in closed spaces these must be well ventilated.
It should not be used for:
zzWarning of dangerous gas concentrations
zzMonitoring 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
zzThe 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.
zzObserve the relevant safety regulations when working at agricultural biogas plants/1/.
zzThe work area must be well ventilated.
zzThe device has been tested to ensure that it is explosion-proof
in accordance with European standards (CENELEC).
zzDo not use this device in oxygen-enriched atmospheres, otherwise it will not be explosion-proof.
zzOnly probe hoses with a hydrophobic filter may be used.
Exception: If the probe has a built-in hydrophobic filter, the hose does not
require any other filters.
zzDevices may only be tested with test gases in well ventilated
areas or outdoors. Test gases must be handled in a professional manner.
zzAlways carry out a device inspection (see Section 5.1) after
the device has suffered an impact (for example, if dropped
accidentally).
zzThe device complies with the limits of the EMC directive. Always observe the information in the manuals of (mobile) radio equipment when using the device close to (mobile) radio
equipment.

Adjustment
WARNING!
The device must only be adjusted by specialist
technicians in well ventilated rooms or in the open
air. Incorrect adjustment can lead to incorrect measurement results.
5.2.1
Scope
The following are adjusted:
zzZero point
zzMeasuring range sensitivity
CAUTION!
Always adjust the zero point first, followed by the
sensitivity.
It is not essential to adjust all gases during adjustment. Every gas
must be adjusted separately.
5.2.2
Preparation
Carrying out an adjustment always takes some time. Leave yourself plenty of time to prepare the necessary steps of the procedure. Have all necessary tools available. Let the device run for
several minutes, to guarantee, for example, that the temperature
is right.
5.2.3
Carry out adjustment
Adjustment of the zero point and the sensitivity is carried out following the same procedure for all gases (see Sections 5.2.3.1
and 5.2.3.2). The adjustment of oxygen is an exception. For this
reason it is described separately (see Section 5.2.4).
33
5 Maintenance
You can access detailed information on the adjustment of the various gases (for example, test gas,
