1． INTRODUCTION
The MWS series of waterproof scales consist of a stainless steel housing and a stainless
steel platform. It has an exterior design of patented IP67 waterproof technology.
The MWS series use of very low amounts of power.
The keypads are light touch switches and the displays are large easy to read liquid crystal type
displays (LCD).
Units include automatic zero tracking, tare and unit shift functions.
2. KEY FUNCTIONS
ZERO
Set the zero point for all subsequent weighing. The display shows zero.
TARE
Tares the scale. Stores the current weight in memory as a tare value, subtracts
the tare value from the weight and shows the results. This is the net weight

3. OPERATION
3.1 Zeroing the display
You can press the ZERO key at any time to set the zero point from which all other weighing
and counting is measured. This will usually only be necessary when the pan is empty. When
the zero point is obtained the zero indicator will appear.
The scale has an automatic re-zeroing function to account for minor drifting or accumulation
of material on the platform. However you may need to press the ZERO key to re-zero the
scale if small amounts of weight are shown when the platform is empty.
3.2 Tare
Zero the scale by pressing the ZERO key if necessary. The zero indicator will be on.
Place a container on the platform, a value for its weight will be displayed.
Press the TARE key to tare the scale. The weight that was displayed will be stored as the
tare value. The value is subtracted from the display, leaving zero on the display. The "TARE"
indicator will be on. As product is added only the weight of the product will be shown.
When the container is removed a negative value will be shown. If the scale was tared just
before removing the container this value is the gross weight of the container plus all product
that was removed.
The zero indicator will also be on as the platform will revert to the operating condition of
when the ZERO key was last pressed.
