1. INTENDED USE - MAIN FUNCTIONS Scales series WTC /LW are designed for counting pieces with same unit mass. Counting process can be realized as: Specification of sample mass (one piece) Calculation of sample mass from some determined amount of samples on the weighing pan TARE functions allows for determination of net mass of measured loads –...
2.2. Keyboard and display window Fig. 2 – buttons and displays Scales are equipped with three displays: mass, piece mass, quantity of pieces, and functional keyboard with numeric and function keys. 2.3. Additional markers Character Description Zero indication of scale Stable weighing result TARE button applied –...
2.4. Function buttons and functions Turn on/off Confirm the quantity of pieces as a standard mass Pressing this button, will cause the display to show in field WEIGHT, message “total” – display of total sum of counted pieces Deleting sum of counted pieces Confirms mass of single unit mass Possibility of setting a threshold for counting pieces mode (after crossing this threshold, scale generates beep signal)
3. OPERATION 3.1. Tarring Place the package of the good(s) on the weighing pan. After stabilization of weighing result, please press button TARE. Display will show ZERO indication. Lower part of the display WEIGHT, the marker of tare application will be visible. Fig.
− After taking the load off the weighing pan, mass indication with negative (minus) sign is visible on the display − Press button ZERO, indication will go back to zero. 4. COUNTING PIECES WITH SAME UNIT MASS 4.1. Single piece mass is known In case unit mass of the counted objects is known, counting mode can be realized in following way: −...
4.2. By determination of single unit mass If unit mass of counted objects is not known, please act as described below: − Place a container for counting pieces on the weighing pan, and press button TARE − Using numeric keyboard of the indicator, insert quantity of pieces (reference mass), which will be used to calculate single piece mass CAUTION: reference mass has to be natural number.
5. SUMMING OF WEIGHING WHILE COUNTING PIECES While counting pieces, it is possible to use summing function. Please follow below procedure: 1. Start counting pieces as described in points 4.1. or 4.2. 2. when scale shows quantity of pieces, press button PLUS 3.

Fig. 8 – view of sum from a few weighings 9. Continuous summing of weighing is possible after pressing button 10. Proceed according to points 5 – 7 CANCELING SUM OF COUNTED DETAILS the moment, the sum of counted details is visible ( please see drawing no. 8), and press button: Scale will go back to weighing mode, sum marker will be no longer visible (marker over M...
6. PROGRAM VALUE WHILE COUNTING PIECES While counting pieces mode, control of quantity takes place in visual way – user should observe display status. For fast processes of quantity building, it is often required to have some limited quantity which can not be exceeded in one package.
7. ACCURACY OF THE SCALE − after switching the scale by pressing button ON/OFF, scale performs auto-test, visible on the display of the instrument. While this process, press button − After cycle completion, scale status will look as below: Fig 11 – choice of readability of the scale −...
8. BACKLIGHT Switching on backlight : − Press and hold button [ZERO] for 3 seconds, on the display described as COUNT backlight parameter value will be displayed. − Below values are accessible bl OFF (backlight off) bl ON (backlight on) bl Aut (automatic control, active only when indication changes and for the next 3 seconds after getting stable.) 9.
