5.1 BACKLIGHT SETTING
The display will show "dxx" To select a different increment value
press the TARE key to change the value then press the ZERO key to
sure.
The standard is to have the backlight operate automatically, turning
off when the scale is not used. The backlight can be set to be "EL
On" , "EL Au" (Automatic) or "EL Off". The maximum battery life
is achieved with the backlight turned off.
Press the TARE key to change the value then press the ZERO key
to sure.

ATW weighting scales operation manual REV: C1, June 2012 ATW weighting scales operation manual
NOTE: The weight must be greater than 20 scale divisions for the
check-weighing to operate.
To disable the Check-Weighing function enter zero into both limits
when the current limits are shown then pressing the ZERO key to store
the zero values.
Note: you can set high/low limit in normal weighing mode.
3.4 CHANGE WEIGHING UNIT
Press UNIT key will change weighing unit circularly. You can select
which unit you can use, see section.
4. BATTERY OPERATION
The scales can be operated from the battery if desired. The battery
life is approximately 90 hours.
When the battery needs charging the arrow above the low battery
symbol under the weight display will turn on. The battery should be
charged as soon as the arrow above the symbol is on. The scale will still
operate for about 1 hours after which it will automatically switch off to
protect the battery.
To charge the battery simply plug into the mains power. The scale
does not need to be turned on.
The battery should be charged for 12 hours for full capacity.
Just above the display is an LED to indicate the status of battery
charging. When the scale is plugged into the mains power the internal
battery will be charged. If the LED is green the batteryhas a full charge.
If it is Red the battery is the battery is being charged.
As the battery is used it may fail to hold a full charge. If the battery
life becomes unacceptable then contact your distributor.
5. PARAMETERS
To set parameters press the limit and UNIT keys at the same time when
normal weighing mode.

1. INTRODUCTION
The ATW series of scales provides an accurate, fast series of
general purpose weighing scales with hold functions.
It haveABS baby tray on an ABS base assembly.
All the keypads are sealed, color coded membrane switches and the
displays are large easy to read liquid crystal type displays (LCD). The
LCD’s are supplied with a backlight.
All units include automatic zero tracking, tare, and hold function.
2. KEY DESCRIPTIONS
ZERO
Set the zero point for all subsequent weighing. The display shows
zero.
A secondary function as "Enter" key when setting parameters or
other functions.
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.
A secondary function, incrementing the active digit when setting a
value for parameters or other functions.
LIMIT
Sets the limits for check weighing. Allows setting of either the low
limit or the high limit or both.
Secondary function , is to move the active digit to the right when
setting values for parameters or other functions.
UNIT
This key will select either kilograms, pounds, ounce and so on for the
weighing unit.

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, within 4% of power
up zero. This will usually only be necessary when the platform is empty.
When the zero point is obtained the display will show the indicator for
zero.
The scale has an automatic rezeroing function to account for minor
drifting or accumulation of material on the platform. However you may
need to press the ZERO key to rezero the scale if small amounts of
weight are shown when the platform is empty.
3.2 TARING
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
is stored as the tare value and that value is subtracted from the display,
leaving zero on the display. The "NET" indicator will be on. As product is
added only the weight of the product will be shown. The scale could be
tared a second time if another type of product was to be added to the first
one. Again only the weight that is added after taring will be displayed.
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 because the platform is back to the same
condition it was when the ZERO key was last pressed.

3.3 CHECK-WEIGHING
Check-weighing is a procedure to cause an alarm to sound when the
weight on the scale meets or exceeds values stored in memory. The
memory holds values for a high limit and a low limit. Either limit can be
used or both can be used.
Press the LIMIT key. The display will show the current High Limit with
the left most digit flashing and the HI symbol on to the left of the display.
To change the value shown use the LIMIT to select the digit to change.
Then use the TARE key to increment the flashing digit. When the
desired value is shown press the ZERO key to accept the value.
After pressing the ZERO key the display will then show the Low Limit,
the LO symbol will be on to the left side of the display Enter the low limit
in the same way the high limit was entered.
After pressing the ZERO key the scale will return to weighing with
the Check-weighing function enabled.
When a weight is placed on the scale the arrows will show if the
weight is above or below the limits and the beeper will sound as
described below.
BOTH LIMITS SET
The display will show OK and the beeper will sound when the weight
is between the limits.
LOW LIMIT SET, HIGH LIMIT is set to zero
The display will show OK and the beeper will sound when
the weight is less than the Low Limit. Above the Low
Limit the display will show HIGH and the beeper will be
off.
HIGH LIMIT SET, LOW LIMIT is set to zero
The display will show LOW and the beeper will be off
when the weight is less than the High Limit. Above the
High Limit the displaywill show OK and the beeperwill be
on.
BOTH LIMITS SET. LOW is set greater than HIGH
The beeper will never sound and the display will show
LOW if the weight is less that the LOW limit, and HIGH if
the weight is greater than the Low Limit. -3-
