To have the realproduct level displayed, an allocation of the measured distance to thepercentage height must be made. To carry out this adjustment, thedistance is entered with full and empty vessel. If these values are notknown, an adjustment with the distance values, e.g. 10 % and 90 % isalso possible. Starting point for these distance specifications is alwaysthe seal surface of the thread or flange. With these settings, the reallevel is calculated. Furthermore the operating range of the sensor islimited from maximum to the required range.The real product level during this adjustment is not important, becausethe min./max. adjustment is always carried out without changing theproduct level. These settings can be made ahead of time without theinstrument having to be installed.In the main menu item "Basic adjustment", the individual submenuitems should be selected one after the other and provided with thecorrect parameter values.Start your parameter adjustment with the following menu items of thebasic adjustment:Proceed as follows:1 Move from the measured value display to the main menu bypushing [OK].1) The values correspond to the actual measured level as well as to the set-tings already carried out, e.g. default setting.Switch-on phaseAddress settingParameter adjustmentCarry out min. adjust-mentVEGAFLEX 67 • Profibus PA 256 Set up with the indicating and adjustment module PLICSCOM32313-EN-120329
