General safety information
●
The
Multitec545
or
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 device too.
●
Observe the relevant safety regulations when working at agri-
●
When working in closed spaces, these must be well ventilated.
SEWERIN recommends: For measurements in closed spaces,
attach the gas outlet adapter to the device to reduce the risk
of high concentrations at H
2
S. The gas outlet adapter can be
purchased as an accessory.
●
The device has been tested to ensure that it is explosion-proof
in accordance with European standards (CENELEC).
●
Do not use this device in oxygen-enriched atmospheres, oth-
erwise it will not be explosion-proof.
● Only 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.
●
Devices may only be tested with test gases in well ventilated
areas or outdoors. Test gases must be handled in a profes-
sional manner.
●
Always perform a device inspection (section 5.1
) after the de
-
vice has suffered an impact (for example, if dropped acciden
-
tally).
●
The 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.
Note:
Follow the advice regarding explosion protection (section 2.3
).
