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 – tare
range equal to max capacity of the instrument – Max.
Functional possibilities
− Setting alarm function for counting (threshold)
− Change of scale readability
− Totalizing in counting pieces mode
− Counting pieces

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)
Deleting the value
TARE button (for determination of net mass)
ZERO button (setting zero point of the scale), switching on/off
scale’s backlight
