Mechanical Rating (Vibration & Shock)
The meter is designed to work in mechanical
environments classified as class M1 as described in
DIRECTIVE 2004/22/EC OF THE EUROPEAN
PARLIAMENT AND OF THE COUNCIL of 31 March
2004 on measuring instruments. This class allows the
instruments to be used in locations with vibration and
shocks of low significance.

The meter is designed to work in Electromagnetic
environments classified as class E2 as described in
DIRECTIVE 2004/22/EC OF THE EUROPEAN
PARLIAMENT AND OF THE COUNCIL of 31 March
2004 on measuring instruments. This class allows the
instruments to be used in locations with
electromagnetic disturbances corresponding to those
normally to be found in industrial buildings.
