1.2 Purpose

The Multitec 540 is a gas measuring device for monitoring 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.

The Multitec 540 is tted with infrared sensors for measuring

methane CH4 and carbon dioxide CO2 as standard. It can also

be tted with electrochemical sensors.

Note:

These operating instructions refer to the Multitec 540

with all additional equipment. They explain the func-

tions of rmware version 1.XXX. The manufac-

turer reserves the right to make technical changes.

All descriptions refer to the device as delivered (fac-

tory settings).

1 General

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 (depend-

ing on the sensors tted).

zMethane CH4

zCarbon dioxide CO2

zOxygen O2

zHydrogen sulphide H2S

If the device is used in closed spaces these must be well ven-

tilated.

It should not be used for:

zWarning of dangerous gas concentrations

zMonitoring 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 con-

centrations above the measuring range limit, this can reduce the

lifetime of the sensor.

1 General

1.4 General safety information

zThe Multitec 540 is a gas measuring device as opposed to a

gas warning instrument. It does not, therefore, warn of danger-

ous toxic and explosive gas concentrations or lack of oxygen. If

you suspect dangerous gas concentrations, always take along

a gas warning instrument too.

zObserve the relevant safety regulations when working at agri-

cultural biogas plants/1/.

zThe work area must be well ventilated.

zThe device has been tested to ensure that it is explosion-proof

in accordance with European standards (CENELEC).

zDo not use this device in oxygen-enriched atmospheres, oth-

erwise it will not be explosion-proof.

zOnly 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.

zDevices may only be tested with test gases in well ventilated

areas or outdoors. Test gases must be handled in a profes-

sional manner.

zAlways carry out a device inspection (see Section 5.1) after

the device has suffered an impact (for example, if dropped

accidentally).

zThe device complies with the limits of the EMC directive. Al-

ways observe the information in the manuals of (mobile) ra-

dio 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:

zSignal light on top of device

(visual signal)

zBuzzer 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:

zInfrared sensor (IR)

zElectrochemical 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-

sion-proof group IIC with hydrogen H2, it must be

used in carrying bag TG8.

3 Operation

3.1 General information on operation

3.1.1 Keys and jog dial

The ON/OFF key is the only control on the device that does not

change its function.

When switched on, the device is operated using the jog dial and

function keys to navigate the display.
