weight.  Enter the value for preset tare using the  keypad, then press the 
[Tare]  key to set the preset zero value. 
   If the display was at zero the weight will show a n egative value equal to 
the  preset  tare  value  entered  and  the  “ Net”  indicator  will  be  on.    If  a 
weight  was  on  the  platform  then  the  preset  value  wi ll  be  subtracted 
from the weight, displaying the NET weight only. 
  
6.3  PARTS
 COUNTING 
6.3.1  Setting Unit Weight
 
I n order to do parts counting it is necessary to kno w the average 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  inputting  a 
known unit weight using the keypad. 
A.  Weighing a sample to determine the Unit Weight 
To determine the average weight of the items to be  counted, you will need to 
place  a  known  quantity  of  the  items  on  the  scale  an d  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  we ight.  Press  [CE]  anytime 
to clear the 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  by pressing [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  numer ic  keys  and  then 
press 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  an d  the  quantity  will 
increase. 
   If  a  quantity  which  is  smaller  than  the  sample  is  p laced  on  the  scale, 
then  the  scale  will  automatically  enhance  the  Unit  Weight  by  re-
calculating  it.  To  lock  the  Unit  Weight  and  avoid  r e-sampling,  press  [U. 
Wt./Units].  
						

							 P a g e 13                     © Adam Equipment Company 2010 
  If  the  scale  is  not  stable,  the  calculation  will  no t  be  completed.  If  the 
weight is below zero, the  “Count” display will show negative count. 
B.  Entering a known Unit Weight 
  If the unit weight is already known then it is poss ible to enter that value 
using the keypad.    
   Enter  the  value  of  the  unit  weight  in  grams,  using  the  numeric  keys 
followed by pressing the   [U.  Wt./Units] key. The "Unit  Weight"  display 
will show the value as it was entered.  
   The  sample  is  then  added  to  the  scale  and  the  weigh t will be displayed 
as well as the quantity, based on the unit weight. 
6.3.2  Counting more parts
 
   After  the  unit  weight  has  been  determined  or  entere d,  it  is  possible  to 
use  the  scale  for  parts  counting.  The  scale  can  be  tared  to  account  for 
the container weight as discussed in the earlier se ction.  
   After  the  scale  is  tared  the  items  to  be  counted  ar e  added  and  the 
"Count"  display  will  show  the  number  of  items,  computed  usi ng  the 
total 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  d isplayed  and  then 
pressing  the  [Smpl]  key.  You  must  be  certain  that  the  quantity 
displayed  matches  the  quantity  on  the  scale  before  pressing  the  key. 
The  unit  weight  can  be  adjusted  based  upon  a  larger   sample  quantity. 
This will give greater accuracy when counting large r sample sizes. 
6.3.3  Check-counting
 
   Check-counting  is  a  procedure  to  cause  an  alarm  to  sound  when  the 
number  of  items  counted  on  the  scale  meets  or  excee ds  a  number 
stored in the memory by using the  [Pst] key. 
   The value to be stored is entered from the keyboard . Enter the numeric 
value  to  be  stored  using  the  numeric  keys.  Then  pre ss  the [Pst] key  to 
store the value. 
   To  clear  the  value  from  the  memory  and  thereby  turn   off  the  check-
counting feature, enter the value "0" and press  [Pst]. 
   During counting if the count is below the setpoint  the “Lo” indicator will 
be on, if it is equal to the set point the  “OK” indicator will be on and if it 
is above the limit the  “Hi” indicator will be on.

6.3.4   Manually Accumulated Totals
 
   The  values  (weight  and  count)  shown  on  the  display  can  be  added  to 
the  values  in  the  memory  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,  the  items  have  been  added  to  the  m emory  for 
accumulation.  The  values  will  be  displayed  for  2  se conds  before 
returning  to  normal.  If  the  accumulated  number  exce eds  6  digits  the 
display  will  show  “diSPEr”,  the  count  is  still  being  stored  correctly  and 
the RS232 printout will still show the correct valu es.  
   The  “Mem”  symbol  will  be  on  when  there  are  values  stored  in  t he 
accumulation memory. 
   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  to  be  pressed 
again. This can continue for up to 99 entries or un til the capacity of the 
“Weight”   display  is  exceeded.  When  the  weight  exceeds  6  dig its  the 
display will show  “diSPEr”. 
   To  observe  the  total stored  value,  press  the   [MR]  key.  The  total  will be 
displayed for 2 seconds.   
   To clear the memory- first press  [MR] to recall the totals from memory 
and then press the  [CE] key to clear all values from the memory. 
 
6.3.6  Automatic Accumulated Totals 
   The  scale  can  be  set  to  automatically  accumulate  to tals  when  a  weight 
is placed on the scale. This eliminates the need to  press 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  the  Section  9.0  on  RS-232  Interface  for  details   on  how  to  enable 
Automatic Accumulation.

8.0  CALIBRATION 
  The  GC  scales  are  calibrated  using  metric  weights  a nd  GCa  scales  are 
calibrated  using  metric  or  pound  weights  depending  on  the  unit  in  use 
before  calibration.    See  the  Service  parameters  sec tion  for  more 
information. 
   The  scale  will  display  a  value  of  the  weight  to  be  used  for  calibration, 
this  value  is  the  last  weight  used  for  calibration.     You  can  enter  a 
different value, if desired. 
   For entering Calibration, see section 7.0 Parameter s 
   When  “F1”  “CAL”  is displayed, press  [Tare]. 
   The  display  will  then  show  unLoAd  to  request  all  weight  be  removed 
from the platform.    
   Press the  [Tare] key to set the zero point. 
   The displays  will  then  show  the  calibration weight  suggested, the  value 
is  shown  as  an  integer  number,  it  is  not  possible  t o  have  fractions  of  a 
kilogram or pound.   For example:    
LoAd  00004 
KiLoS 
  Place  the calibration  weight  on  the platform  If  the   calibration weight  is 
different  from  the  value  shown,  Press   [CE] to  clear  the  current  value 
then enter the correct value.    
   Press  [Tare]  to calibrate. 
   When calibration is done the display will show  “SPAn”  “PASS”. 
   Remove the weight. The scale will return to normal  weighing.   
   If an error message  “SPAn” “FAIL” is displayed, then repeat the process. 
   After calibration, the scale should be checked whet her the calibration is 
correct. If necessary, repeat calibration. 
NOTE: 
GCa scales will have  the lb or kg  indicator on, to  show the unit of the weight 
requested.  If  the  scale  was  in  pounds  before  starti ng  the  calibration,  the  weights 
requested  will  be  in  pound  values  or  if  the  scale  w as  weighing  in  kilograms  then 
metric weights will be requested.
