Electromagnetic compatibility (EMC)
12. ELECTROMAGNETIC COMPATIBILITY (EMC)
The THERM 2420 measuring instrument complies in full with the safety re-
quirements specified in the EU directive relating to electromagnetic compatibili-
ty (EMC) (89/336/EWG).
The following standards have been applied in evaluating the product.
IEC 61326:1997+A1:1998+A2:2000
IEC 61000-6-1:1997
IEC 61000-4-2: 1995+A1:1998+A2:2000 8kV
IEC 61000-6-3:1996 IEC 61000-4-4: 1995+A1:2000 2kV
IEC 61000-4-3: 1995+A1:1998+A2:2000 3V/m
The following advisory notes must be observed when operating the device.
1. If the standard sensor is extended (1.5 meters) care must be taken to ensure that
the measuring lines are not laid together with high-voltage power cables and that,
if necessary, they are properly shielded so as to prevent spurious interference be-
ing induced in the system.
2. Using the device in strong electromagnetic fields may aggravate measuring errors
(<50
µ
V at 3 V/m and 1.5 meters thermocouple sensor). After exposure to such ir-
radiation ceases, the device will again operate within its technical specifications.
