JWP digital weighing scales operation manual

 

The  display  will  show  "ACC    1"  and  then  the  total  in  memory  for  2 

seconds  before  returning  to  normal.    If  the  optional  RS-232  interface  is 

installed 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"  and 

then show the new total. 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 the total number of items "ACC    xx" and the total 

weight before returning to zero.    The totals will also be   

printed via the RS-232 interface. 

To  erase  the  memory  press 

PRINT

  to  view  the  totals  and  then  press  the 

SMPL/C

 key to clear the memory. 

Note: M+/Print function only available when stable (        indicator on) 

 

7.2 AUTOMATIC ACCUMULATION 

When  the  scale  has  been  set  to  Automatic  Accumulation  the  value  is 

stored in memory automatically.     

Add a weight to the scale, the beeper will sound when the scale is stable to 

signify the value is accepted.    Remove the weight. 

The  display  will  show  "ACC  1"  and  the  totals  in  memory  when  the  scale 

returns to zero.      Adding a second weight will repeat the process.   

While the weight is on the scale it is permissible to press the 

PRINT

 key 

to store the value immediately.    In this case the scale will not store the

1 INTRODUCTION                               

The JWP series of scales provides an accurate, fast and versatile series of 

general  purpose  weighing  scales  with  counting,  %  weighing  and 

check-weighing  functions.  The  scales  built  in  a  thermal  printer  that  could 

support  continuous  paper.  And  also,  they  have  an  expanded  bi-directional 

RS-232 interface for communication with a PC as an optional. 

There are 4 models in each series, with capacities up to 45 kg.   

They all have stainless steel weighing pan assembly. 

All  the  keypads  are  sealed,  color  coded  membrane  switches  and  the 

displays are large easy to read liquid crystal type displays (LCD). The LCD’s 

are supplied with a backlight. 

      All units include automatic zero tracking, audible alarm for pre-set weights, 

automatic tare, and an accumulation facility that allows the count to be stored 

and recalled as an accumulated total. 

 

2 KEY DESCRIPTIONS   

                       

Zero 

or   

Set the zero point for all subsequent weighing. The display shows zero. 

A  secondary  function          ,  of  "Enter"  key  when  setting  parameters  or 

other functions. 

Tare 

or     

Tares  the  scale.  Stores  the  current  weight  in  memory  as  a  tare  value, 

subtracts the tare value from the weight and shows the results. This is   

the net weight. Entering a  value using the keypad will store that value as 

the tare value. A secondary fu , of incrementing the active digit
