9.4.5  Net/Total     
This  function  allows  the  user  to  see  the  total  of  a ll the  net  weights,  the  value 
of  which  is  displayed  on  smaller  digits  above  the  m ain  display.  The  current 
net  weight  is  shown  on  the  main  display.  The  [Tare]  key  functions  the  same 
way as in the normal weighing.    
Steps:   
  Press  [Mode]  and  then  [Up]  or [Down]   to  select  Net/Total.    When

immerse  the  sample  in  the  chosen  liquid.  The  densit y  of  the  liquid  must  be 
known or determined from a look-up table. 
 
For  water  and  ethanol  the  density  will  be  calculate d  based  on  the 
temperatures entered using the numeric entry method  (see section 7.1) 
 
Steps:  
  Press  [Mode] and then  [Up] and  [Down]  keys to select density 
 
  Press  [Enter] to enter Density mode.

DENSITY OF LIQUID     
  
When  finding  the  density  of  a  liquid,  it  is  necessa ry  to  weigh  a  sample  of 
known volume in air and then in the liquid. The vol ume of the sample must be 
entered by the user. The last known volume is store d for use at any time. 
  
If  using  the  density  determination  kit,  the  volume  of  the  plumb  is  marked  on 
its support, i.e. 10.123    
Steps:  
  Press  [Mode] and then  [Up] and  [Down]...

10.0  CALIBRATION 
 
The  PGW  XXXe  series  can  only  be  calibrated  with  an  external  mass.    The 
PGW  XXXi  series  can  be  calibrated  with  either  an  in ternal  mass  (default 
method)  or  an external mass  (if  setup by  the  user  t o do this).     See  the  User 
Parameters section. 
 
10.1  MANUAL CALIBRATION 
 
Pressing the  [Cal] key will start calibration. Calibration can also be  initiated by 
a  change  in  internal...

10.2  AUTOMATIC CALIBRATION 
 
The  balance  will  have  the  ability  to  calibrate  (or  ask  for  calibration)  when  the 
balance  has  automatic  calibration  enabled  and  the  c onditions  of  the 
automatic calibration have been meet.  
 
Conditions that will cause an automatic calibration  are:  
1.  Internal temperature change greater than a prese t amount, typically 2ºC 
for Precision balances.  
2.  Time since last calibration...
