4.0 OPERATION
4.1 ZEROING THE DISPLAY
 Press the [Zero] key when the platform is empty.
 [Zero] key may be pressed at any time to set the zero point
from which all other weighing and counting is measured.
 When the zero point is obtained the “O” indicator will be on in
the left bottom corner of the LCD.
 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.
4.2 TARING
 Zero the scale by pressing the [Zero] key, if necessary.
 The “O” 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. It is subtracted from the
displayed value, leaving zero on the display. The NET
symbol will be on at the right top corner to indicate that the
weight displayed is the net weight.
 As the product is added, only the net weight 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 products those were removed.
 The “O” indicator will also be on because the platform is back
to the same condition as it was when the [Zero] key was last
pressed.
 To cancel the tare value, press [Tare] again.

4.3 WEIGHING
 After zeroing the display and taring the container, place the
sample in the container to determine the weight of the
sample. The weight will also be displayed through a bar-
graph at the bottom of the LCD.
 The display will show the weight and the units of weight
currently in use. The stable indicator will be on. To
change the weighing units, press [Mode] to cycle through the
options of units those are enabled. See the Parameter
section to enable or disable the weighing units.
 The accumulated value in the memory will be cleared when a
new weighing unit or during recalling the memory, %
weighing or parts counting is selected.
4.4 PERCENT WEIGHING
 The scale will allow a sample weight to be shown as 100%.
Then any other weight placed on the scale will be displayed
as a percentage of the original sample.
 For example is 350g is placed on the scale and the [%] key
is pressed the display will show 100.00%. Removing the
350g weight and place a 300g weight on the scale. The
display will show 85.71% as 300g is 85.71% of 350g.
 Note: The scale may jump by large numbers unexpectedly if
small weights are used to set the 100% level. For example, if
only 23.5g is on a scale with 0.5g increments and the scale is
set to 100%, the display will show 100.00%. However, a
small change of weight will cause the display to jump to
102.13%, as one scale division (0.5g) increase to 24.0g will
be equivalent to a 2.13% increase.
 Pressing the [%] key again will return the scale to normal
weighing.

© Adam Equipment Company 2004 9
4.5 PARTS COUNTING
 When the scale is in normal weighing mode, pressing the
[Smpl] key will start the parts counting function.
 Before beginning, tare the weight of any container that will be
used, leaving the empty container on the scale.
 Place the number of samples on the scale. The number
should match the options for parts counting, 10, 20, 50, 100
or 200 pieces.
 Press the [Smpl] key.
 The scale will initially show "SP10" asking for a sample size of
10 parts. Press [Mode] to cycle through the options: 10, 20,
50, 100, 200 and back to 10.
 Press [Smpl] again when the number matches the number
of parts used for the sample. As more weight is added the
display will show the number of parts (PCS) with respect to the
chosen sample size.
 Press [Mode] to display unit weight (W/P), total weight (g) or
the count (PCS). The total and the unit weight are shown in the
current units.
 Press [Smpl] to return to normal weighing.
4.6 ACCUMULATION
 When the scale is set for automatic accumulation, the weight
will be added to the memory when the scale becomes stable.
The scale must return to zero before another weight is
added.
 When the scale is set to manual accumulation (See the
Parameter Section) the weight displayed will be stored in
memory when the [Print] key is pressed and the weight is
stable.
 The display will show "ACC 1" followed by the total value in
the memory for 2 seconds before returning to displaying the
weight of the item on the scale.

© Adam Equipment Company 2004 10
 The weight will be output to a printer or PC.
 Remove the weight, allowing the scale to return to zero and
put a second weight on.
 Press [Print], the display will show "ACC 2" followed by the
new total in the memory for 2 seconds before returning to
displaying the weight of the item on the scale.
 Continue until all weights have been added.
 To view the totals in memory press the [Print] key when the
scale is at zero. The display will show "ACC xx" (where “xx” is
the total number of readings) and the total weight, before
returning to zero.
 The total will also be printed via the RS-232 interface.
 To clear the memory, press [Smpl] immediately after
pressing [Print].
5.0 PARAMETERS
 The scale has 5 parameters that can be chosen by the user
to set the scale.
 To set the parameters press the [Mode] key during self-
checking test.
 After a few seconds, the display will show the first function
"F1 UNT".
 To view the current settings of each parameter, press the
[Zero] key.
 Press the [Zero] key again to cycle through the other
