JWP digital weighing scales operation manual

 

when  the  weight    on  the  scale  meets  or  exceeds  values  stored  in 

memory.    The memory holds values for a high limit and a low limit.    Either 

limit can be used or both can be used. 

Press the 

LIMIT

 key.    The display will show the current High Limit with 

the left most digit flashing and the HI symbol on to the left of the display.. 

To change the value shown use the 

%

/

    and the 

LIMIT

/

 to select 

the digit to change.    Then use the 

TARE

/

 key to increment the flashing 

digit.    When  the  desired  value  is  shown  press  the 

ZERO/ENTER

  key  to 

accept the value.    If you want to reset the value to zero press the 

SMPL/C

 

key to clear the value. 

After  pressing  the 

ZERO/ENTER

  key  the  display  will  then  show  the 

Low Limit, the LO symbol will be on to the left side of the display.   

Enter the low limit in the same way the high limit was entered. 

After pressing the 

ZERO/ENTER

 key the scale will return to weighing with 

the Check-weighing function enabled. 

When a weight is placed on the scale the arrows will show if the weight 

is above or below the limits and the beeper will sound as your setting (see 

detail in section 9). 

BOTH LIMITS SET 

The display will show OK when the weight is between the limits.       

 

LOW LIMIT SET, HIGH LIMIT is set to zero 

The  display  will  show  OK  when  the  weight  is  less  than  the  Low  Limit.   

Above the Low Limit the display will show HIGH.

weight.  In  the  weighing  mode,  press  this  key  to  shift  the  unit.  In  the 

percent . 

weighing mode, press this key to display the weight temporary then after 3

3.BASIC OPERATION   

                                       

3.1 ZEROING THE DISPLAY 

You  can press  the  ZERO/ENTER key  at  any  time to  set  the  zero  point 

from which all other weighing and counting is measured, within 4% of power 

up  zero.  This  will  usually  only  be  necessary  when  the  platform  is  empty. 

When the zero point is obtained the display will show the indicator for zero. 

The  scale  has  an  automatic  rezeroing  function  to  account  for  minor 

drifting or accumulation of material on the platform. However you may need 

to  press  the 

ZERO/ENTER 

key  to  rezero  the  scale  if  small  amounts  of 

weight are shown when the platform is empty. 

3.2 TARING 

Zero the scale by pressing the 

ZERO/ENTER

 key if necessary. The zero 

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 and that value is subtracted from the display, leaving 

zero on the display. The "NET" indicator will be on. As product is added only 

the weight of the product will be shown. The scale could be tared a second 

time if another type of product was to be added to the first one.
