The  user  can  store  and  recall  up  to  103  PLU  values  as  PLU1,  PLU2,  PLU3  and 
PLU00 to PLU99.    
 
The  keys  labelled [PLU1]  and  [PLU2]   are  used  to  immediately  recall  the  most 
frequently used PLU values saved as PLU1 and PLU2. The [PLU+]  key is used to 
access the other values saved as PLU3 and PLU00 to PLU99.  
 
To recall one of these PLU values the following procedure applies. 
  1.  To recall PLU1, simply press  [PLU1].  
2.  The same applies to PLU2, simply press  [PLU2]. 
3.  To recall one of the other PLU values, press  [PLU+]. The display 
will  show  “ LOAd”      “P\fS      00 ”      ”      ”.    If  a  number  (00  to  99)  is 
entered  immediately,  then  the  value  saved  against  the  entered 
PLU  number  will  be  recalled.  If  nothing  is  entered  within  a  few 
seconds  of  pressing  the  [PLU+]  key,  the  value  saved  for  PLU3 
will be recalled.  
 
For example: 
  Press  [PLU+]. 
Press  [1] and then  [4] immediately.     
Display will show “LOAd ”   “P\fS   14 ”   ”   ” and then the PLU value 
for PLU 14 will be displayed. 
 
OR  
 
Press  [PLU+].       
Wait for few seconds. 
Display will show “ LOAd”   “P\fS   00 ”   ”   ” and then the PLU value 
for PLU 3 will be displayed. 
 
If the item is loaded on the pan, the  Total Price window will show the total cost. If 
nothing  is  loaded,  only  the  PLU  value  saved  for  the  location  will  be  displayed  in 
the  Unit Price window and the  Total Price window will display “0,00  ”.

 5.0  CALIBRATION  
5.1  CALIBRATION PROCEDURE 
 
The scales are sealed to prevent unauthorised calibration.  
 
Contact Adam Equipment or your supplier for more details. 
 
 
  
 
The  calibration  of  the  AZ
extra  scale  is 
accomplished  by  removing  the  label  at 
the base of the scale which covers a hole 
through which the PCB can be accessed. 
If  your  scale  is  not  provided  with  this 
hole,  you  need  to  break  the  security 
seals  and  remove  the  top  cover  to  gain 
access  to  the  circuit  boards  inside.  See 
the figure on the security seal below. 
 
 
WARNING:  CALIBRATION OF THE SCALES MAY MAKE IT ILLEGAL TO USE 
THE  SCALES  FOR  SALES  OF  GOODS.  CONTACT  YOUR  TRADING 
STANDARDS OFFICE FOR FURTHER ASSISTANCE. 
 
5.2  SECURITY SEALS 
 
 
To seal the scale a lead-wire seal can be 
used  as  shown  below.  The  base  has  a 
metal  pin  that  protrudes  through  the 
cover. The security seal may be threaded 
through  this  metal  pin,  making  it 
impossible  to  remove  the  cover  without 
damaging  either  the  security  seal  or  the 
enclosure. 
 
Metrology  labels  and  additional  security 
measures  may  be  added  to  the  scale  as 
required by the national legislation. 
 
 
An  alternative  method  of  sealing  the  scales  is  to  have  a  seal  covering  the  joint 
between  the  base  and  the  cover.    If  this  seal  is  broken  the  scale  must  be  sealed 
by  the  relevant  authorities  using  either  the  lead  wire  seal  or  an  acceptable  seal 
between the cover and the base.
