SECTION 1 INTRODUCTION
The BW/BWS/CW/VW series of bench scale provides an accurate, fast and versatile
series of general purpose weighing scale with counting and check-weighing
functions.
There are 3 series s within the range, the platform size from 350mm x 450mm to
600mm x 800mm, the capacity range from 30kg to 1000kg
All the displays are large easy to read liquid crystal type displays (LCD). The LCD’s
are supplied with a LED backlight.
All units include automatic zero tracking, audible alarm for pre-set weights, and an
accumulation facility that allows the individual weights to be stored and recalled as
an accumulated total.

SECTION 3 INSTALLATION
3. 1 GENERAL INSTALLATION
The s should be sited in a location that will not degrade the accuracy.
Avoid extremes of temperature. Do not place in direct sunlight or near air
conditioning vents.
Avoid unsuitable tables. The tables or floor must be rigid and not vibrate. Do not
place near vibrating machinery.
Avoid unstable power sources. Do not use near large users of electricity such as
welding equipment or large motors.
Avoid high humidity that might cause condensation. Avoid direct contact with water.
Do not spray or immerse the s in water.
Avoid air movement such as from fans or opening doors. Do not place near open
windows.
Keep the s clean.
Do not stack material on the s when they are not in use.
3. 2 INSTALLATION OF BW/BWS/CW/VW SERIES
The pillar is attached to the base using a bracket that must first be attached to the
base frame using the 4 bolts supplied. The Pillar is secured to the bracket using 2
set screws. The cable from the base to the indicator module is run through the tube,
out through the plastic support at the top. Excess cable can be stored within the
tube.
The BW/BWS/CW/VW Series comes with a stainless steel platform packed
separately. Place the platform in the base.
Level the scale by adjusting the four feet. The scale should be adjusted such that the
bubble in the spirit level is in the center of the level and the scale is supported by all
four feet. If the scale rocks readjust the feet.
Attach the indicator module to the pillar by sliding it over the bracket with the flanges
engaged in the groves on the base. Attach the cable from the base to the
connector on the rear of the indicator.
Attach the AC power adapter to the connector on the back of the indicator.

If you want to scale can’t work when not level, you can add one mercury level bubble,
connect 2 wire to K1, when scale not level, mercury level bubble short, indicator will
show “err l”, when this message appear, please adjust scale level.
If you don’t need this function, just leave K1 unused.

SECTION 4 KEY DESCRIPTIONS
ON/ OFF or
Turn on or off the power.
Zero
Set the zero point for all subsequent weighing. The display shows zero.
A secondary functionof "Enter" key when setting parameters or other functions.
Tare
Tares the . Stores the current weight in memory as a tare value, subtracts the tare
value from the weight and shows the results.
A secondary function incrementing the active digit when setting a value for
parameters or other functions.
Press Zero and Tare key together in normal weighing mode will turn on/off animal
function.(when enter/escape animal mode, you will hear beeper on twice)
MR
Memory recall key, show total accumulate weight in memory.
In setting mode, this key used to move active digits right.
M+
Accumulate key, store current weight in memory.
In setting mode, this key used to move active digits left.
Press M+ and MR key for MC (memory clear)
Print
To print the results to a PC or printer using the optional RS-232 interface.
Press Print during selfchecking will enter setting mode.
G/N
Gross weight/net weight shift key, Hold this key for 3 seconds to shift the unit.
Secondary function (ESC) , is to return to normal operation when the is in a
parameter setting mode.
