You will find practical information about working with this application and about the different settings. (You will find information about non-application-specific system settings in Chapter 5). 10.
The “Percent Weighing” application 94 With only a few exceptions, the settings available in the “Percent Weighing” application are identical to those of the “Weighing” application (Chapter 6.2). Only the settings that are different are described below. These settings are contained in the following menus: “Function Keys”: Additional function keys are available for percent weighing. “Info Fields”: Additional information fields are available for percent weighing.
The “Percent Weighing” application 95 10.3.4 Additional Unit for percent weighing In the menus for the “Display Unit” and the “Info Unit”, in addition to the known weighing units, the unit “%” (percent) is available (provided that a reference has already been determined). Note: For percent weighing you do not need to explicitly select the “%” unit, since the display unit is always switched over to“%” automatically when the reference is determined.
The “Percent Weighing” application 96 Report Footer Line On the second and third pages of this submenu you can specify which special items of information for percent weighing should be printed out in the footer line of the weighing report after the results (individual values). The same settings are available as for the header line and the individual values (“Reference%”,“Reference”,“Target value”,“+Tol” and “–Tol”, as described above).
The “Percent Weighing” application 97 10.4.2 Percent weighing to a target value The “Percent Weighing” application provides you with additional functions to make weighing to a specified target value easier. In the description that follows, it is assumed that the reference for the percent weighing has already been determined. Requirements Before you can input a target value and the associated tolerances, the function keys shown at left must be activated (Chapter 10.3.2).
The “Piece Counting” application 98 11 The “Piece Counting” application In this chapter you will be introduced to the “Piece Counting” application. You will find practical information about working with this application and about the different settings. (You will find information about the non-application-specific system settings in Chapter 5.) 11.1 Introduction to the “Piece Counting” application The “Piece Counting” application allows you to count pieces.
The “Piece Counting” application 99 With only a few exceptions, the settings available in the “Piece Counting” application are identical to those of the “Weighing” application (Chapter 6.2). Only the settings that are different are described below. These settings are contained in the following menus: “FixPcs”: Allows you to specify a fixed reference piece count. “Function Keys”: Additional function keys are available for piece counting.
The “Piece Counting” application 100 “CL Last”: Clears the last piece count that was saved (Chapter 11.4.2). “Nominal”: Specifies the desired target piece count (Chapter 11.4.3). The target piece count is also used as the reference for the tolerances (as described below). “Abs/Diff”: Switches the weight display between the number of pieces that have already been weighed and the number of pieces still needing to be weighed to reach the target piece count (Chapter 11.4.3).
The “Piece Counting” application 101 11.3.5 Additional unit for piece counting In the menus for the “display unit” and “info unit”, the unit “PCS” (pieces) is available in addition to the usual weighing units (provided that a reference piece weight was already determined). Note: When you do piece counting, you do not have to explicitly select the unit “PCS”, because the display unit is always automatically switched to “PCS” when the reference piece weight is determined.
The “Piece Counting” application 102 Reporting the result On the second and third pages of this submenu you can speciry which additional information items for piece counting should be included in the report of the results: “Max n”: Specified maximum number of piece counts in a series. “Nom, +/–Tol”: Specified target piece count and selected tolerances. “>Tol+,
The “Piece Counting” application 103 Determining the reference Place the desired number of reference pieces on the weighing pan. The balance uses these reference pieces to determine the average (mean) piece weight, which serves as the basis for piece counting. When you have placed on the weighing pan exactly the number of pieces which was programmed for the “FixPcs” function key (Chapter 11.3.2), press this function key. (The programmed reference piece count is displayed below the key, e.g.“Fix10”).
The “Piece Counting” application 104 11.4.2 Totaling piece counts and including them in statistics Settings So you can total piece counts and include them in statistics, you must activate at least one of the 3 functions keys shown at left (Chapter 11.3.3), and at least one of the function keys for reference determination (Chapter 11.4.1). In addition, we recommend you also to activate the two function keys shown at left.
The “Piece Counting” application 105 – If you saved an incorrect piece counting result by mistake, you can remove it from the statistics with the “CL Last” function key. However, this is only possible for the last result that was saved. The “CL Last” function key is only active if there are values saved in memory; otherwise the key is dimmed and cannot be operated. After you have cleared a result, the key is inactivated and only functions again after you have included the next result in the statistics.
The “Piece Counting” application 106 11.4.3 Counting to a target value The “Piece Counting” application has additional functions which make it easier for you to count to a specified target value. You can use these functions for individual piece counts as well as for series of piece counts with statistics. In the following description it is assumed that the reference for the piece count has already been determined.
