1 For your safety For your safety Authorised personnel All operations described in this documentation must be carried out only by trained, qualified personnel authorised by the plant operator. During work on and with the device, the required personal protective equipment must always be worn. Appropriate use The VEGABAR 82 is a pressure transmitter for process pressure and hydrostatic level measurement. You can find detailed information about the area of application in chapter "Product description".
1 For your safety EU conformity The device fulfils the legal requirements of the applicable EU direc- tives. By affixing the CE marking, we confirm the conformity of the instrument with these directives. You can find the EU conformity declaration on our website under www.vega.com/downloads. Permissible process conditions For safety reasons, the instrument must only be operated within the permissible process conditions. You can find detailed information on the process conditions in chapter "Technical data" as well as on the type label. The permissible process pressure range is specified by "MWP" (Maximum Working Pressure) on the type label, see chapter "Struc- ture". The MWP takes the element of the measuring cell and process- ing fitting combination with the weakest pressure into consideration and may applied permanently. The specification refers to a reference...

Position correction pressure measurement In this menu item you compensate the influence of the installation position of the instrument (offset) on the measured value. 5. Zero adjustment In this menu item you carry out the zero adjustment for the process pressure. Enter the corresponding pressure value for 0 %. 6. Span adjustment In this menu item you carry out the span adjustment for the process pressure Enter the corresponding pressure value for 100 %.
5 Set up with the display and adjustment module 100% Fig. 8: Parameter adjustment example "Min./max. adjustment, level measure- ment" Min. level = 0 % corresponds to 0.0 mbar Max. level = 100 % corresponds to 490.5 mbar If these values are not known, an adjustment with filling levels of e.g. 10 % and 90 % is also possible. By means of these settings, the real filling height is then calculated.
