Low Voltage Directive 2014/35/EU
*2
EN 61010-1 (Class I
5
, Pollution Degree 2
6
)
1 Does not apply to specially ordered or modified products.
2 Only on models that have CE/UKCA marking on the panel.
3 This is a Class A instrument. This product is intended for use in an industrial environment. This product may cause
interference if used in residential areas. Such use must be avoided unless the user takes special measures to reduce
electromagnetic emissions to prevent interference to the reception of radio and television broadcasts.
4 This is a Group 1 instrument. This product does not generate and/or use intentionally radio-frequency energy, in the form of
electromagnetic radiation, inductive and/or capacitive coupling, for the treatment of material or inspection/analysis purpose.
5 This is a Class I instrument. Be sure to ground this product's protective conductor terminal. The safety of this product
is guaranteed only when the product is properly grounded.
6 Pollution is addition of foreign matter (solid, liquid or gaseous) that may produce a reduction of dielectric strength or
surface resistivity. Pollution Degree 2 assumes that only non-conductive pollution will occur except for an occasional
temporary conductivity caused by condensation.
