6.1.1 FREE (Reference settings) The FREE option allows the user to set any reference other than the fixed available reference. (Default value is 001 and maximum possible value is 999) Procedure ð Place the empty container on the pan. ð Press the key briefly to tare the balance. ð Press the key briefly until “pcs” appears on the display. Your balance now needs the weight of a reference number. ð Press and hold the key until you are prompted to load the reference pieces.
6.1.3 Updating Settings The Update feature improves the precision of piece counting results. The average piece weight (reference) is recalculated with each reference optimization. Because the new pieces that have been placed in the weighing pan increase the basis for the calculation, the references, and therefore the result of the piece count, are more exact. Select the UPDATE feature from the reference menu.
6.2 Percent Weighing (%) The “Percent weighing” function enables you to weigh in to a preset value (1, 10, 20,50, 100%, Free, 100r, 100L, AtroM, AtroD) and to determine deviations from this target value. Percent Weighing (%) presupposes that you have preselected the “F per” function in the menu Procedure ð Place the empty container on the pan. ð Press the key to tare the balance. ð Press the key briefly until “PER (%)” appears on the display.
If the balance is connected externally to PC or Printer through RS 232 C then, whenever user enter into the reference menu of Percent Weighing function & make changes in the reference setting, automatically printout is generated on the Peripheral attached. In the printout, reference percent “pRef” and reference weight “wRef” is printed. After this user can Press Print Key to Print the reading on the display.
6.2.2 Differential Weighing The Differential Weighing application is used to analyze changes in the weight of one or more samples. The first step is to determine the initial weight of the sample (weighing in). Selected components are then separated from or added to the sample. This includes procedures such as drying, centrifugation, filtering, incineration, vaporization, coating, etc. After the sample has been processed, it is re-weighed (residual weight).
Percentage Weighing (%) (in 100R / 100L / AtroM / AtroD) 100L% (Loss Content) Percent Weighing (%) presupposes that you have preselected the “F per” function in the menu Procedure ð Press the key to tare the balance. ð Press the key briefly until “PER (%)” appears on the display. Your balance now needs the weight of a reference percent (%). ð Press and hold the key until you are prompted to load the reference PER (%).
6.3 Custom Unit The custom unit feature enables you to perform weighing in a customized unit i.e. weighing can now be performed in a unit other than standard available 15 units. Procedure Custom unit presupposes that you have selected the 'F Cust' in the user menu. ð Place the empty container on the pan. ð Press the key briefly to tare the balance. ð Press the key briefly until “CSt” appears on the display.
E.g. If the settings are as follows, Factor = 1.02356 Accuracy = 0.00 LSD = 50 Now if 50 gm of weight is loaded on the pan the calculation for displayed weight will be as follows, Weight * Factor = 50 * 1.023456 = 51.1728 The displayed weight will be 51.150 The second digit after decimal point will change in multiples of 5 because, Accuracy * LSD = 50 * 0.001 = 0.05 You can use the key at any time to switch the display between custom unit display, weighing unit 1 and weighing unit 2.
6.4 Animal Weighing The animal weighing feature enables you to perform weighing of unstable samples (live animals). The balance calculates the weight as the average of a defined number of individual weighing operations. You can select from the two available animal weighing modes i.e. Auto animal weighing and manual animal weighing. For Animal Weighing Process to start two conditions should be satisfied, the weight of the animal kept on the pan should be higher than 100 display increment i.e.
6.4.2 Auto Animal Weighing Auto Animal Weighing presupposes that you have selected the 'F Anl AUTO' in the user menu. Auto animal weighing proves to be beneficial when the balance is used majority for animal weighing and less for simple weighing thus reducing the time required for animal weighing. Procedure ð Place the empty container on the pan. ð Press the key briefly to tare the balance. ð Press the key briefly until “ ” and “AUTO” symbol appears on the display.
6.5 Formulation The formulation feature allows individual weighing values to be summed to a total. User can select from two available formulation modes i.e. Manual formulation and auto formulation. Maximum no of weights that can be summed is 99.
6.5.2 Auto Formulation Auto formulation presupposes that you have selected the 'F Form AUTO' in the user menu. Auto formulation proves to be beneficial when the balance is used in majority for formulation weighing and less for simple weighing thus reducing the time required for formulation as compared to manual formulation. ð Place the empty container on the pan. ð Press the key briefly to tare the balance. ð Press the key briefly until Fol and AUTO is displayed on the display.
6.6 Check Weighing This feature is used to check whether a sample corresponds to a preset target or is with a specific tolerance range. The results displayed can also be available on external port, which with the help of electronic processing can be used to control additional devices. The check weighing procedure will always be carried out in unit 'gm'. Check weighing presupposes that you have selected the 'F CHw' in the user menu. Procedure ð Press the key briefly to tare the balance.
For Low Range Load the weight on the pan and the balance will display the results according to the preset values of target and tolerance. E.g. If the values are as follows, TARGET = 150.0000 gm HI = 155.0000 gm LOW = 145.0000 gm Now if 144.0000 gm is loaded on the pan the display shows LL indicating that the loaded weight is less than the low value set. If 156.0000 gm is loaded on the pan the display shows HH indicating that the loaded weight is greater than the high value set.
6.7 Totalization The totalization procedure allows individual weighing pieces to be summed to a total. User can select from two available formulation modes i.e. Manual totalization and auto totalization. Maximum no of weights that can be summed is 99. Store component pieces with • Display zeroed automatically after value is stored, and • Automatic printout (print application parameters) • Of the last added pieces and • Of the total number of pieces.
6.7.2 Auto Totalization Auto totalization presupposes that you have selected the 'F tot AUTO' in the user menu. Auto totalization proves to be beneficial when the balance is used in majority for totalization weighing and less for simple weighing thus reducing the time required for totalization as compared to manual totalization Procedure ð Place the empty container on the pan. ð Press the key briefly to tare the balance.
6.8 Density Determination The density is determined applying the principle of Archimedes, which states that any body immersed in a fluid becomes lighter by an amount equal to the weight of the fluid that it has displaced. Purity of gold can also be determined on the basis of density. The weighing unit of density determination will be 'grams'. Density determination presupposes that you have selected the 'F Den' in the user menu.
