Operating the Combics 2 Minimum Load The minimum load at initialization is configured in the Application settings (3.5: minimum load for automatic taring and automatic printout; 3.6: minimum load for automatic initialization). You can choose from the following ten levels for this setting: 1 digit (no minimum load) 2 digits 5 digits 10 digits 20 digits 50 digits 100 digits 200 digits 500 digits 1000 digits The “digits" here refer to the weighing platform intervals in the connected weighing platform. If the interval of the connected platform is 1 g, for example, and 1000 digits are required, you must place at least 1000 g (= 1000 intervals = 1000 digits) on the weighing platform for initialization. If the interval of the connected platform is 5 g, you have to place at least 5000 g on the platform for initialization to achieve the number of digits required in the above example. You can increase the resolution for determining the reference weight by changing the Application settings for resolution (3.9) to use display resolution + 1 decimal place, display resolution + 2 decimal places, or internal resolution. With the setting for “Display resolution + 1 (2) decimal place(s)", the resolution of the net value is increased by one or two decimal places; “Internal resolution" uses the maximum resolution available in the weighing platform. Once the limit is exceeded by the load, initialization can begin. If the load on platform is too light for initialization, the following will occur when you try to initialize the application: – The error inf 29 is displayed. – A warning signal (double-beep) is emitted – The weighing platform is not initialized Reference Sample Updating In the Application settings under 3.12, you can define whether the reference sample is updated automatically. Reference sample updating is performed automatically only when the following 6 criteria are met: 1. Menu item 3.12.3 is selected in the Application setup menu 2. The current piece count must exceed the original piece count by at least two 3. The current piece count is less than twice the original piece count (does not apply to the first update if the piece count is entered using a bar code scanner). n n+2 2·n Range for reference sample updating “Old” ref. sample qty. Pieces on platform 4. The current piece count is less than 100. 5. The internally calculated piece count (such as 17.24 pcs) differs by less than ± 0.3 pcs from the whole number (17 pcs in this example). 6. The weighing platform is stable in accordance with the defined stability parameter. If automatic reference sample updating is selected in the Application settings and the piece count (pcs) is displayed, the AUTO symbol is displayed in addition to the Counting symbol (Z). If the reference sample has been updated, OPT is displayed continuously next to the "AUTO" symbol. During a reference sample updating operation, both 0pt and the current reference sample quantity are shown briefly in the main display. At the conclusion of reference sample updating, a beep is sounded and the new reference weight and reference sample quantity are stored. You can view these values when the weighing platform is in Info mode. Counting with Two Weighing Platforms You can use two weighing platforms simultaneously with the Counting application. When using two platforms, you can choose from the following operating modes: – Counting with two platforms of the same type – Counting with one reference platform and one weighing platform Counting with Two Platforms Use this mode to count different types of sample material with different weights. For example, count the lighter-weight pieces on one platform and the heavier pieces on the other. After starting a counting routine on one platform, press n to toggle to the other platform, re-initialize the application and begin a new counting operation. You can define which of the two platforms is active when the Combics is switched on (8.11). This setting is independent of automatic initialization of the Counting application. Counting with One Reference Platform and One Weighing Platform In this mode, the reference platform is a high-resolution weighing platform with a relatively low maximum capacity. The other platform is used for counting large amounts, and has a high capacity with a relatively low resolution. This allows you to both determine the reference sample quantity with high resolution; i.e., very precisely, and to count large amounts of parts, without requiring an expensive high-resolution, high-capacity weighing platform. The system toggles automatically to the reference platform for initialization (Ref is displayed). Following initialization, the system toggles to the counting platform. The system does not toggle automatically for automatic reference sample updating; the update is based on whichever platform is active. – The preset reference sample quantity is stored 45
