The WTC Series precision balance is designed for fast and precise weighing in laboratory conditions. It can be used in areas with no access to mains (230V), as an internal rechargeable battery comes standard. The balance is equipped with a stainless steel weighing pan, RS 232 output, and backlit LCD display.
1- Check weighing function is used for checking whether the measured sample mass is within the predefined threshold values, Low [LO] and High [HI]. The thresholds are given in [g] and [kg] units. Current state of a sample being measured is signaled by means of pictograms located on a display for laboratory balances, for industrial scales Stacking System is used. This visual +/- inspection is in operation during segregation, control or packing process of products for which mass has been determined with a specified tolerance, eg. 12860 g 961
2- Parts Counting: Function using mass measurement for determination of measured items quantity. Mass of a single item is required for this process. It may be either estimated through weighment or taken from a database. For items counting the following algorithm is used: all items mass / single item mass = quantity. Function operation is supported by a mechanism of Automatic Correction of Accuracy. This allows updating single item mass in course of the process. To a certain extend Automatic Correction of Accuracy eliminates error which may be a result of different mass values of seemingly alike single elements. For industry solutions items counting may be simultaneously carried out with check weighing and dosing thus industry solutions feature audio signaling base informing that specified number of items has been weighed. It is possible to apply weighing systems using few platforms of different MAX capacities and different accuracies
3- Percent setup function is used for comparison of measured products with mass standard. Mass of a mass standard may be a numeric value taken from a database or it may be determined through a measurement process. Each measured product is compared to mass standard, mass of which is presumed as a model 100% ideal mass. For products weighing less than the mass standard, obtained results are lower than 100%, for products weighing more, the obtained results are greatly excessed.
4- Totalizing: Function adding new mass value to already obtained one. This allows determining mass content of the mixture, being a composition of number of different consistence components. Totalizing is limited by maximum capacity parameter.
5- Animal Weighing: Process of mass determination for a product which may unwillingly reposition within the weighing pan. Mass determination in such cases requires much longer period of time when compared to typical weighing process. It is the user who defines period of time needed for control of measured product mass. The user cans thus optimize the function depending on the measured product characteristics.
6- Peak Hold: Function registering the greatest temporary indication occurring in course of the weighing process. It is most often used in medical scales in order to hold the measurement indication.
