    2009-04-10 1 Identifying the instrument version Identifying the instrument version The nameplate is glued onto the housing top. The supply voltage must correspond to the voltage given on the nameplate. All necessary settings are described in these operating instructions. Any manipulations that are not described in the operating instructions (or even expressly forbidden) will endanger your rights under the instrument warranty ! If you have any problems, please contact the nearest subsidiary or the head office.
