Electromagnetic Environment
IEC 61326-2-2
CISPR 11: Group 1, Class A
Group 1: Equipment has intentionally generated and/or uses
conductively-coupled radio frequency energy that is necessary for the
internal function of the equipment itself.
Class A: Equipment is suitable for use in all establishments other than
domestic and those directly connected to a low voltage power supply
network that supplies buildings used for domestic purposes. There
may be potential difficulties in ensuring electromagnetic compatibility
in other environments due to conducted and radiated disturbances.
Caution: This equipment is not intended for use in residential
environments and may not provide adequate protection to radio
reception in such environments.
Emissions that exceed the levels required by CISPR 11 can occur
when the equipment is connected to a test object.
The equipment may not meet the immunity requirements of this
standard when test leads and/or test probes are connected.
For current measurement with jaw, add 1 mA to specification for EMC
fields from 1 V/m to 3 V/m.
