9 Electromagnetic compatibility (EMC)

9.1 General hints

The installation and use of the electrical multi-function balances MWA
300-K1M, MWA 300-K1PM, MWA 300-K1NM, MWA 300-K1PNM
requires special precautionary measures as outlined in the EMC
information below.
This device complies with the limits set for medical electrical devices of group 1,
class B (as per EN 60601-1-2).
Electromagnetic compatibility (EMC) describes a device's ability to perform reliably
within an electromagnetic environment without causing inadmissible electromagnetic
interference at the same time. Amongst other things, such disturbances may be
emitted by connecting cables or the air.
Inadmissible disturbances from the environment may result in incorrect displays,
inaccurate measured values or incorrect behaviour of the multi-function balances
MWA 300-K1M, MWA 300-K1PM, MWA 300-K1NM, MWA 300-K1PNM . The multi-
function balances MWA 300-K1M, MWA 300-K1PM, MWA 300-K1NM, MWA 300-
K1PNM, too, may in certain cases cause such malfunctions in other devices. To
eliminate problems of that kind, we recommend you to take one or several of the
measures listed below:
• Change the alignment or distance of the device to the source of failure.
• Install and use the multi-function balances MWA 300-K1M, MWA 300-K1PM,
MWA 300-K1NM, MWA 300-K1PNM in one and the same place.
• Connect the multi-function balances MWA 300-K1M, MWA 300-K1PM, MWA
300-K1NM, MWA 300-K1PNM to a separate power source.
• For further questions please contact our customer services.
Disturbances may be caused by improper modification or add-ons to the device or
not recommended accessories (such as power units or connecting cables). The
manufacturer will not be responsible for these. Modifications may also result in a loss
of authorisation relating to the use of the device.
Devices emitting high frequency signals (mobile telephones, radio
transmitters, radio receivers) may cause interference in the multi-
function balances MWA 300-K1M, MWA 300-K1PM, MWA 300-
K1NM, MWA 300-K1PNM. Do not use these near multi-function
balances MWA 300-K1M, MWA 300-K1PM, MWA 300-K1NM, MWA
300-K1PNM. Chapter 8.4 contains details about recommended
minimum distances.
