Suggested Trial Weight Mass and Location 
 
Your  instrument  can  assist  with  balancing  operations  by  calculating  an 
appropriate  trial  weight  mass  and  location  for  you.  
 
MORE: See Machine Information for help with calculating the trial 
weight mass. 
 
 
Manually Enter Balancing Data 
 
You  can  enter  amplitude  and  phase  values  manually  for  the  initial,  trial, 
and  trim  readings.  Doing  so  enables  you  to: 
•  Interrupt  the  balancing  process  without  saving  the  values,  then 
re-enter  these  later  and  continue  balancing. 
•  Experiment  with  different  trial  weight  masses  and  placements 
to  see  the  effect  on  the  imbalance,  without  having  to  attach 
weights  to  the  machine. 
•  Calculate  the  effect  of  further  trim  balances.  
•  Change  the  units  used  in  a  final  balancing  report  by  selecting 
different  units,  then  re-entering  the  collected  values. 
 
To  enter  a  value  manually: 
1.  Work  through  your  balancing  setup  process  as  usual.   
2.  Press    to  take  a  reading  —  The  CH1    icon  will  display.  
 
NOTE: For a dual plane balance, the CH2 icon will also display. 
 
3.  To  enter  your  own  values  for  CH1,  press    (or  press    for  CH2 
for  two  channel  measurements). 
4.  Press    to  enter  an  amplitude  value  >  Press    to  enter  a 
phase  value.   
5.  Press    twice  to  exit  and  return  to  the  Initial,  Trial,  or  Trim 
Reading  menu  and  continue  your  balancing  job.
