This procedure serves for inputting the actual volume or mass of the measured specimen If all the specimens measured in a particular collection have the same volume it is sufficient to input this volume only once If the volume varies from specimen to specimen it is necessary before or after the measurement but before the evaluation of each specimen to input the correct volume or mass of the measured specimen The Mass is possible to input for field variation measurement only not for AMS After starting this procedure the Volume or Mass depending on Volume or Mass mode saved in the configuration file appears on the screen 7 If the volume of the measured specimen is the same one only hits ENTER while if the volume is different one should input new actual volume of the measured specimen Function Key 7 Help This key invokes the help procedure To quit help page press ESC key Function Key 9 Kill This key breaks the current activities and clears the measured and input specimen data Function Key 10 Aux This key switches the program to the AUXILIARY MENU 40 Brief description of the Auxiliary Menu Fl lt BSus gt F2 lt ACmd gt F2 lt CStd gt F2 lt OrPar gt F2 lt AnFac gt F2 Vol F2 Mass F2 Sigma F2 List F3 Cal F4 Holder F5 Field F6 lt ActVol gt F6 Mass F7 Help F8 lt Freq gt F9 Kill F10 Main Convention Measuring the Bulk
