 FILTER    Set  a  value  for  the amount  of filtering to  be 
done ranging from 1 to 10. A larger number  
means  more  filtering  and  a  slower 
response. 
 
 STABILITY   
Set  a  value  to  be  used  to  determine 
balance  stability,  set      a  value  of  1,  2,  5  or  
10d.    A  larger  number  corresponds  to  a  
larger stable zone. Default is 5

Keep  a  record  of  the  passcode  to  ensure  you  can  acc ess  this  section  again.  
If  however  you  have  forgotten  your  passcode  you  can   still  gain  access  by 
entering a universal code.    
If  you  have  forgotten  the  current  passcode  a  code  o f  “15”  will  always  allow 
you to enter the Supervisor area.      
Using  the  Supervisor  menus  go  to  the  PASSCODE  secti on  and  reset  the

15  SAFETY AND MAINTENANCE 
   
CAUTION 
Use  the  AC  adapter  designed  by  the  manufacturer  for   the  balance.  Other 
adapters may cause damage to the balance. 
 
Avoid overloading or dropping material onto the pla tform which could damage 
the balance.    Do  not  spill  liquids  on  the  balance  as  it  is  not  wa ter-resistant.  Liquids  may 
damage the case and if it gets inside the balance i t may cause damage to the 
electronics. 
 
Material  that...

Mechanical Problems:  
The  balances  consist  of  complicated  and  fragile  mec hanical  devices.    They 
can be damaged by placing a weight on it which is t oo high for the balance or 
by dropping the balance or occasionally shipping it  without taking care.   The 
most fragile parts are the flexures.   Dust, dirt,  spills and other foreign objects 
in the balance can also cause problems.    
Electronic Problems:  
These  are  the  rarest  of  the  problems...

BALANCE DOES NOT FUNCTION  
Problems  Possible causes  Suggestions 
The balance is dead  
when power is applied  Power supply failure  Check adapter is working 
Check adapter is correct for the balance  
Normal adapter is 15VDC, 800mA. 
*Power supply circuit board failure 
*Short circuit on any circuit board 
The display does not  
turn on but the 
calibration motor 
moves when power is 
applied  Power is getting to 
balance, display is not 
working

Balance is very  
unstable and does not 
weigh correctly 
Mechanical problems   
Balance programming   
 
Electronic problems  *A complete inspection of the  
mechanics to look for sources of friction.
 
*Verify the A/D is also unstable.  If the  
A/D is OK then suspect the 
programming of the balance.  Reset 
parameters, check linearity and redo the 
calibration.  
Some electronic problems can also  
cause this.  But all mechanical problems 
must be resolved...
