DISPLAYS
The scales have three digital displays. The displays show WEIGHT, UNIT
WEIGHT and COUNT.
WEIGHT DISPLAY
A 6 digit display which displays the weight on the scale.
Arrowheads adjacent to the symbols will indicate the following:
Zero Indicator, "Zero"
Net Weight Indicator
UNIT WEIGHT DISPLAY
This display will show the unit weight of a sample. This value is either input by
the user or computed by the scale. The unit of measure is grams on all scales
with Kilogram weight units or in pounds on scales that show pounds.
There is an insufficient number of samples to accurately
determine the count:
Indicates that a unit weight must be entered either
manually, or via the sample process.
COUNT /PCS DISPLAY
The display will show the number of items on the scale or the value of the
accumulated count. See OPERATION section.
Scale is in Accumulate Mode
Low battery Symbol
Display Reading is Stable

SCALES usa © 2004 Page 9 of 16
OPERATION
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, It is active within 4% of power up
zero. This will usually only be necessary when the platform is empty. When
the zero point is obtained the Weight display will show the indicator for zero.
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
ZERO to re-zero the scale if small amounts of weight are shown when the
platform is empty.
TARING
There are two methods to enter a tare value. The first uses the weight on the
platform and the second uses a value input by the user.
Normal 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 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.
Press the TARE key again to remove the tare weight .
Pretare:
This method allows you to enter a value for the tare weight from the
keypad. This is useful if all containers weigh the same, or if the
container is already full but the net weigh is required and the tare
weight of the container is known.

SCALES usa © 2004 Page 10 of 16
Remove all weight from the platform, and press the ZERO key to zero
the display.
Press the P.Tare key and the unit weight display will flash PrEtA
Enter the value for the Tare weight including decimal values (50.00)
using the keypad, press P.Tare to store the tare value. The weight will
show a negative value equal to the tare.
Place the container on the platform. The display will then show the
weight of the container minus the tare weight. Then when the full
container is put on the platform the tare value will be subtracted from
the gross weight displaying only the net weight of the contents.
PARTS COUNTING
SETTING UNIT WEIGHT
In order to do parts counting it is necessary to know the average piece weight
of the items to be counted. This can be done by weighing a known number of
the items and letting the scale determine the average unit weight or by
manually entering a known weight using the keypad.
WEIGHING A SAMPLE TO DETERMINE THE UNIT WEIGHT
To determine the average weight of the items to be counted it will be
necessary to place a known quantity of the items on the scale and then
to key in the number of items being weighed. The scale will then divide
the total weight by the number of items and display the average unit
weight.
Zero the scale by pressing the ZERO key if necessary. If a container is
to be used, place the container on the scale and tare as discussed
earlier.
Place a known quantity of items on the scale. After the weight display
is stable enter the quantity of items using the numeric keys followed by
SMPL key. The number of units will be displayed on the "Count"
display and the computed average weight will be shown on the "Unit
Weight" display.
As more items are added to the scale, the weight and the quantity will
increase.
If the scale is not stable, the calculation will not be completed. If the
weight is below zero, the “Count”display will show all dashes.
The SMPL key may be pressed during the counting to update the unit
weight.

SCALES usa © 2004 Page 11 of 16
ENTERING A KNOWN UNIT WEIGHT
If the unit weight is already known then it is possible to enter that value
using the keypad.
Enter the value of the unit weight using the numeric keys followed by
pressing the U.Wt key. The "Unit Weight" display will show the value
as it was entered.
Add the sample to the scale and the weight will be displayed as well as
the quantity based upon the unit weight.
When weighing in kilograms the unit weight is shown in grams. When
weighing in pounds the unit weight is displayed in pounds.
STORING A UNIT WEIGHT
Up to 10 unit weights may be stored in the scale memory and recalled later.
Obtain the unit weight by sampling or by entering it as described in the
above sections.
Press and hold the U.Wt key for approximately 2 seconds
Press any of the numeric keys (0-9) to store the unit weight in the
corresponding memory.
RECALLING A STORED UNIT WEIGHT
Clear the scale display and set the zero point and Tare any container
on the scale.
Press and release the numeric key corresponding to the location of the
stored unit weight.
The Count Display will begin flashing.
Now double click U.Wt key (Press twice quickly)
The stored unit weight will appear in the unit weight display and you
may begin counting..

SCALES usa © 2004 Page 12 of 16
COUNTING MORE PARTS
After the unit weight has been determined or entered it is possible to use the
scale for parts counting. The scale can be tared to account for package
weight as discussed in an earlier section.
After the scale is tared, the items to be counted are added and the "Count"
display will show the number of items computed using the weight and the unit
weight.
It is possible to increase the accuracy of the unit weight at any time during the
counting process by entering the count displayed then pressing the SMPL
key. You must be certain the quantity displayed matches the quantity on the
scale before pressing the key. The unit weight will be adjusted based upon a
larger sample quantity. Use of larger sample sizes will give greater accuracy
when counting larger quantities.
AUTOMATIC PART WEIGHT UPDATES
The scales will automatically update the unit weight when a sample equal to
or less than the sample already on the platform is added. A beep will be
heard when the value is updated. It is wise to check that the quantity is
correct when the unit weight has been updated automatically. This feature is
turned off as soon as the number of items added exceeds the count used as
a sample. This feature may be enabled or disabled in the scale setup mode.
PRESET CHECK-WEIGHING
Check-weighing is a procedure to cause an alarm to sound when the weight
on the scale falls within a preset range. The weight range is set as follows.
1. Press the ALARM key while the scale is either loaded or unloaded. Hi
will show in the weight display
2. Key in the high limit weight value and press the ALARM key again.
3. Now Lo will be displayed. Key in the low limit weight value and press
the U.Wt key to store the value and return to the normal weighing
mode.
4. To disable the function, follow the above steps entering “0”for the high
and low preset values
PRESET COUNTING ALARM
Pre-Set Counting is a procedure to cause an alarm to sound when the
quantity of items on the scale falls within a preset range. The item count
range is set as follows.

Smpl key to store the value and return to the normal counting mode
4. To disable the function, follow the above steps entering “0”for the high
and low preset values
ACCUMULATED TOTAL(Count or Weight)
The values (weight and count) shown on the display can be added to the
values in the memory as follows
1. Press the ADD key. The "Weight" display will show the total weight,
the "Count" display will show the total accumulated count, and the
"Unit Weight" display will show the number of times that items have
been added to the accumulation memory. The values will be displayed
for 2 seconds before returning to normal.
2. The scale must return to zero or a negative number before another
count or weight can be added to the memory.
3. Additional product can then be weighed or counted and the ADD key
pressed again. This can continue for up to 99 entries, or until the
weight capacity is reached.
4. To observe the total stored press the TOTAL key. The totals will be
displayed for 2 seconds.
5. To clear the memory press TOTAL to recall the totals from memory
and then press the CLEAR key to clear all values from memory.
BATTERY OPERATION
The scales can be operated from the battery if desired. The battery life is
approximately 70 hours. When the battery needs charging the arrow above
the low battery symbol under the COUNT/PCS 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 10 hours after which it will automatically
switch off to protect the battery. To charge the battery, simply plug the AC
Adapter into the scale and the AC power outlet. IF the LED is red, the battery
is receiving a charge. The scale does not need to be turned on. The battery
should be charged for 12 hours for full capacity. When the battery life
becomes unacceptable then contact DigiWeigh or Scales USA for current
replacement information.
