4.0  KEY DESCRIPTIONS 
 
 
  
[0-9,  •]   
These  keys  are  used  to  manually  enter  a  value  for  t are  weights,  unit  weight 
and  sample  size.  A  secondary  function  is  to  enter  a lpha-numeric  characters 
for PLU descriptions etc. 
  
[CE]    
Pressing this key clears the unit weight or an erro neous entry. It also clears 
the memory accumulation when the total is displayed . 
  
[M+]   
This key is used to add the current count to the ac cumulator. It also recalls 
the memory when pressed with no load on the scale.  Up to 99 values or full 
capacity of the weight display can be added. Also p rints the displayed values 
when Auto print is switched off.    
[Smpl]      
This is used to enter the number of items of a samp le. 
 
[PLU]      
To store and recall the Product Look Up sample info rmation. 
 
[U. Wt./Units]      
This key is used to enter the weight of a sample ma nually. It will also change 
the weighing units when other units are enabled.  
[PST]    
 
To set the upper limit for the number of items coun ted. When this upper limit 
is exceeded the scale will sound the beeper. A seco ndary function is to use it 
access the menus for user settings.  
[Print]  
It is used to print the weighing data.

[Local Rem]     
This key is used to select the local or remote scal e. 
  
[Tare/Zero]    
This key has a combined Zero and Tare function.   
If  the  net  weight  is  below  ±2%  of  maximum  then  it  a cts  as  a  Zero  key.  This 
sets the zero point for all subsequent weighing by  setting the display to zero. 
It  also  tares  the  scale  by  storing  the  current  weig ht  in  the  memory  as  a  tare 
value,  subtracting  the  tare  value  from  the  total  we ight  and  displaying  the 
results as a net weight.   
 
5.0  DISPLAYS 
 
The scales have three display windows-  Weight, Unit Weight  and Count . 
 
 
 
 
5.1  WEIGHT WINDOW 
   
This consists of a 6 digit display to indicate the  weight on the scale.  
  
An arrow above the symbols will indicate the follow ing:

5.2  UNIT WEIGHT WINDOW 
 
·  This  display  will  show  the  unit  weight  of  a  sample.   This  value  is 
either  entered  by  the  user  manually  or  computed  by  the  scale. 
The  unit  of  measure  is  either  gram  on  all  scales  wi th  kilogram 
selected as weighing unit or in pounds. 
 
·  When  the  scale  has  determined  that  there  is  insuffi cient  number 
of  samples  to  accurately  determine  the  count,  an  ar row  will  be 
shown above  Smpl. 
 
·  When  the  unit  weight  is  not  large  enough  to  determi ne  an 
accurate count, the arrow will show at  U.Wt. 
 
·  When  a  value  has  been  entered  into  the  memory,  the  arrow 
above  M+ will be on. 
 
·  In  both  the  cases  the  scale  continues  to  operate  an d  the 
indicators are to alert the user of a potential pro blem.   
   
5.3  COUNT WINDOW 
 
· This  display  will  show  the  number  of  items  on  the  s cale  or  the 
value of the accumulated count. See the OPERATION s ection. 
 
·  An arrow above the symbols will indicate the follow ing: 
 
Checkweighing is active during counting, Ck Pcs   
Checkweighing is active during weighing,    “Ck Wt” 
 
Checkweighing is active, result is above the High L imit, “High” 
 
Checkweighing is active, result is between the Low  and High 
Limit, “OK”  
Checkweighing is active, result is below the Low Li mit, “Low” 
  
·  Just under the “ Count” display is an LED to indicate the status of 
the  battery  charging.    When  the  scale  is  plugged  in to  the  main 
power  the  internal  battery  will  be  charged.    If  the   LED  is  green, 
the  battery  has  a  full  charge.    If  it  is  red,  the  b attery  requires 
further charging and yellow indicates the battery i s being charged.

 6.0  OPERATION 
 
·   The  basic  weighing  functions  are  same  for  both  the   local  and  remote 
scales.    However  the  number  of  weighing  divisions  m ay  be  less  on  the 
remote scale dependant on the total capacity of the  load cell/s used. 
 
·  Each scale (local or remote) has the ability to co unt parts based on the 
current  unit  weight.  This  is  best  obtained  by  weigh ing  and  counting    a 
sample on the local scale which may have the best s ensitivity. Then the 
scale  can  be  switched  to  the  remote  where  large  qua ntities  can  be 
counted. 
 
·   Each  scale  has  a  separate  tare  value  that  can  be  e ntered  through  the 
keypad  or  by  placing  a  weight  on  the  platform  and  p ressing  the 
[Tare/Zero]   key.    The  tare  value  for  each  scale  is  retained  as   the  user 
switches between the remote and local scales. 
 
·   Either scale can be used to determine a unit weigh t. 
 
·  When the scale is switched from local to remote, a  clear display will be 
shown  to  identify  the  change  and  the  scales  will  co unt  based  on  the 
tare  and  unit  weight  currently  in  use  for  the scale  selected.  Display for 
the change is: 
 
“c h A n g E” ”L o c A L“ and “c h A n g E” ”r e m o t E “ 
 
The  display  will  be  based  on  the  7  segment  interpre tations, 
some of the letters are shown later. 
 
·   The  switch  from  local  scale  to  remote  scale  should   be  possible  at  any 
time by pressing the  [Local/Rem] key.  
 
     
NOTE: For frequently used items, counting is made easier  by using PLU 
numbers (Product Look Up). Up to 100 PLU’s can be s tored and 
recalled.  Place the item on the pan and enter the  appropriate PLU 
number using the keypad. The scale will display the  Total Weight, Unit 
weight and the Count of the item in the respective  windows.   
See section 6.4

6.1  ZEROING AND TARING THE DISPLAY 
 
The  Tare  and  Zero  function  are  combined  into  one  ke y.    When  the 
gross  weight  is  within  ±2%  of  the  zero,  set  at  powe r  on  for  either  scale 
then a new zero is set.  If the gross weight is gre ater than ±2% then the 
tare function is performed. 
  
ZEROING 
 
·  You  can  press  the  [Tare/Zero]  key  at  any  time  to  set  the  zero 
point  from  which  all  other  weighing  and  counting  is   measured. 
When  the  zero  point  is  obtained  the  Weight display will show the 
indicator at “ Zero”. 
 
·  The  scale  has  an  automatic  re-zeroing  function  to  a ccount  for 
minor  drifting  or  accumulation  of  material  on  the  p latform. 
However  you  may  need  to  press  the  [Tare/Zero]  to  re-zero  the 
scale  if  small  amounts  of  weight  are  still  shown  ev en  when  the 
platform is empty. 
  
TARING   
Preset tare values can be used with both the local  and remote scale. If a new 
tare value is to be used, there are two methods for  entering a tare value. The 
first  method  uses  the  weight  on  the  platform  and  th e  second  uses  a  value  to 
be entered by the user.  
First method of entering a tare value:
 
 
·  Zero the scale by pressing the  [Tare/Zero] key, if necessary. The arrow 
indicator over “ Zero” will be on. 
 
·  Place  a  container  on  the  platform,  a  value  for  its   weight  will  be 
displayed. 
 
·  Press  the  [Tare/Zero]  key  to  tare  the  scale.  The  weight  that  was 
displayed  is  stored  as  the  tare  value  and  that  valu e  is  subtracted  from 
the  display,  leaving  zero  on  the  display.  The  arrow   over  Net  will  be 
on.  As  product  is  added  only  the  net  weight  of  the  product  will  be 
shown.  The  scale  could  be  tared  a  second  time  if  an other  type  of 
product  was  to  be  added  to  the  first  one.  Again  onl y  the  weight  that  is 
added after taring will be displayed.

·   When  the  container  is  removed  a  negative  value  wil l  be  shown.  If  the 
scale  was  tared  just  before  removing  the  container  this  value  is  the 
gross  weight  of  the  container  plus  all  products  tho se  were  removed. 
The  zero  indicator  will  also  be  ON  because  the  plat form  is  back  to  the 
same condition as it was when the  [Tare/Zero] key was last pressed. 
 
Second method of entering a tare value: 
 
·  This  method  allows  you  to  enter  a  value  for  the  ta re  weight  from  the 
keypad.   This is useful if all containers are the  same or if the container 
is  already  full  but  the  net  weight  is  required  and  the  weight  of  the 
container is known. 
 
·  Remove  all  weights  from  the  platform,  press  the  [Tare/Zero]  key  to 
zero the display. 
 
·  Enter  the  value  for  the  Tare  weight  including  deci mal  point  using  the 
keypad, press  [Tare/Zero] 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  conta iner  minus  the  tare 
weight. When the full container is placed on the pl atform the tare value 
will  be  subtracted  from  the  gross  weight  displaying   only  the  net  weight 
of the contents. 
 
·  If  the  value  input  is  not  consistent  with  the  incr ement  of  the  scale,  the 
scale  will  round  the  tare  value  to  the  nearest  valu e  possible.  For 
example,  if  a  tare  value  of  103g  is  entered  into  th e  60Kg  scale  with  5g 
readability, then the display will show -105g. 
 
·   The tare value for each scale is held in memory so  that they are not lost 
when the active scale changes.

6.2  MEMORY FUNCTIONS 
 
The 
[M+]  key  will  add  the  results  of  a  weighing  into  memory ,  regardless  of 
whether the local or remote scale is being used for  the weighing.   
  
6.2.1 Manual accumulation 
 
·   The  values  (weight  and  count)  shown  on  the  display   can  be  added  to 
the  values  in  the  accumulator  by  pressing  the  [M+]  key.  The   Weight 
display will show the total weight, the  Count display will show the total 
accumulated count and the  Unit Weight display shows the number of 
times items have been added to the accumulation mem ory. The values 
will be displayed for 2 seconds before returning to  normal. 
 
·  The  scale  must  return  to  zero  or  a  negative  number   before  another 
sample can be added to the memory.  
 
·   More  products  can  then  be  added  and  the  [M+]  key  pressed  again. 
This  can  continue  for  up  to  99  entries  or  until  the   capacity  of  the 
“ Weight ” display is exceeded. 
 
·  To observe the total value stored, press the  [M+] key when the scale is 
at zero. The total will be displayed for 2 seconds.  
 
·  To  clear  the  memory,  first  press  [M+]  to  recall  the  total  from  the 
memory and then press  [CE] to clear all values from the memory. 
 
6.2.2  Automatic accumulated total 
 
·  The scale can be set to automatically accumulate t otal when a weight is 
placed  on  the  scale.  This  eliminates  the  need  to  pr ess  the  [M+]  key  to 
store  values  into  the  memory.    However  the   [M+]  key  is  still  active  and 
can  be  pressed  to  store  the  values  immediately.    In   this  case,  the 
values will not be stored when the scale returns to  zero. 
 
·  See Section 7 for  enabling Automatic Accumulation

6.3  PARTS COUNTING 
 
The  basic  function  of  parts  counting  is  same  for  bo th  the  scales.  In  order  to 
do  parts  counting  it  is  necessary  to  know  the  avera ge  weight  of  the  items  to 
be  counted.  This  can  be  done  either  by  weighing  a  k nown  number  of  the 
items  and  letting  the  scale  determine  the  average  u nit  weight  or  by  manually 
inputting a known unit weight using the keypad.   
Either  of  the  scales  can  be  used  to  determine  the  s ample  unit  weight  or  for 
the manual entry which can be used to count using e ither of the scales.  
 
It  is  possible  to  increase  the  accuracy  of  the  unit   weight  at  any  time  during 
the  counting  process  by  entering  the  count  displaye d  and  then  pressing  the 
[Smpl]   key.  You  must  ensure  that  the  quantity  displayed  m atches  the 
quantity  on  the  scale  before  pressing  the  key.  The  unit  weight  can  be 
adjusted  based  on  a  larger  sample  quantity.  This  wi ll  give  greater  accuracy 
when counting larger sample sizes.   
6.3.1  Weighing a sample to determine the Unit Weigh t 
 
To  determine  the  average  weight  of  the  items  to  be counted  place  a  known 
quantity of the items on the scale and then enter t he quantity being weighed. 
The  scale  will  then  divide  the  total  weight  by  the  number  of  samples  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  ta re  as  discussed 
earlier. 
 
·   Place  a  known  quantity  of  items  on  the  scale.  Afte r  the  “Weight ” 
display  is  stable  enter  the  quantity  of  items  using   the  numeric  keys 
followed  by  pressing  the   [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  a nd  the  count  will 
increase. 
 
·   If the scale is not stable, the calculation will n ot be completed.  
 
·  If  the  weight  is  below  zero,  the  “ Count”  display  will  show  negative 
count.

6.3.2  Entering a known Unit Weight 
 
·   If  the  unit  weight  is  already  known  then  it  can  be   entered  using  the 
keypad.    
 
·   Enter  the  value  of  the  unit  weight  using  the  numer ic  keys  followed  by 
pressing  the  [U.  Wt.]  key  within  few  seconds  while  the  display  is 
flashing. If no action is initiated within a few se conds, the Unit Weight ” 
display  will  revert  to  the  previous  value,  otherwis e  it  will  show  the  new 
value that has been entered.  
 
·   The sample is then added to the scale and the weig ht 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 shown in pounds. 
 
·   After the unit weight has been determined or enter ed, the scale can be 
used  for  parts  counting.  The  scale  may  be  tared  to  account  for  the  net 
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  us ing  the 
weight and the unit weight. 
 
·   It  is  possible  to  increase  the  accuracy  of  the  uni t  weight  at  any  time 
during  the  counting  process  by  manually  entering  th e  sample  quantity 
and  then  pressing  the  [Smpl]  key.  You  must  ensure  that  the  quantity 
displayed  matches  the  quantity  on  the  scale  before  pressing  the  key. 
The  unit  weight  will  be  adjusted  based  upon  a  large r  sample  quantity. 
This will give greater accuracy when counting large r sample sizes. 
  
6.3.3  Automatic update of unit weight  
 
·  The scales will automatically update the unit weig ht when a sample less 
than  the  initial  sample  count  is  added.  A  beep  will   be  heard  when  the 
value is updated. It is wise to check the quantity  is correct when the unit 
weight has been updated automatically. 
 
·   To lock the unit weight and prevent Auto-update, p ress [U.Wt.].  
 
·  This  feature  is  turned  off  as  soon  as  the  number  o f  items  added 
exceeds the count used as a sample. 
 
·

6.3.4  Count pre-set or check-weighing 
 
Check-weighing  (or  Count  Pre-setting)  is  a  procedur e  to  cause  an  alarm  to 
sound  when  the  net  weight  (or  the  number  of  items)  on  the  scale  meets  or 
exceeds  a  number  stored  in  memory.  The  value to be  stored is entered from 
the keyboard.     
 
SETTING OF PRESET LIMITS 
 
It is possible to set a high and low limit for eith er counting or weighing (using 
net  weight).    When  the  [Pst]  key  is  pressed  the  user  can  select  either 
counting or weighing and then set the lower and upp er limit. 
  
For example: 
 
ACTION  DISPLAYS 
Press  [Pst] 
“CHECk  ”   “ nEt “    “         “   if currently in the weighing mode 
 
Press  
[U.Wt/Units]  “CHECk    ”      “  CoUnt  “        “                  “
    to  toggle  from  weighing  to 
counting 
Press  [Print]  
“Hi  cnt”    “0.3  2  3  4”    “            ”   The  current  high  count  limit  is 
displayed, press  [CE] to clear and change if needed. 
If using net weight the display will show  “Hi WEG”   
 
Press  [Print]  
“lo  cnt”    “0.0  2  3  4”    “            ”   The  current  low    count  limit  is 
displayed, press  [CE] to clear and change if needed. 
If using net weight the display will show  “Lo WEG”   
 
Press  [Print]  Return to weighing with limits set.   
   
·
  Clearing  of  either  or  both  the  limits  is  allowed.  Both  limits  cleared  will 
disable the Preset altogether. 
 
·  If Preset Weight was selected the first display wo uld show “Hi WEG” and 
“ Lo WEG ”.  
 
·  The beeper will work as described in the Beeper Pa rameter.
