Leveling  the  Brookfield  Viscometer:

  It  is 

essential that the  viscometer be  level for proper 
operation.    A  level  is  located  at  the  top  of  the 
viscometer.    Loosening  the  left  thumb  screw 
allows  the  viscometer  to  be  leveled,  or  the  use 
of  the  leveling  feet  attached  to  the  stand.    Be 
sure to re-tighten the left thumb screw in order to 
secure the viscometer.   

 

Power:

  Connect  the  line  cords  for  both  the 

Digital Programmable Brookfield Viscosity Liquid 
Bath  (K34715/K34716)  and  the  Koehler  or 
Brookfield  Rotational  Viscometer  (please  see 
section 3.1 for part numbers) to a properly fused 
and  grounded  receptacle  with  the  correct 
voltage  as  indicated  in  section  3  or  on  the 
information plate at the back of the unit.   

 

NOTE:

 

 

It  is  important  that  the  electrical 

power  supply  note  vary  more  than  10%  of  the 
apparatus  specified  voltage.    The  unit  will  not 
function properly and/or may be damaged. 

 

WARNING:

  For  user  safety,  please 

disconnect  the  line  cords  whenever  performing 
any  maintenance  operations  and/or  cleaning  of 
the unit. 
 

WARNING:

 

Do  NOT  turn  the  power  on 

unless the bath is filled with the proper medium.  
Low  liquid  level  exposes  the  heater  which  may 
ignite the vapors above the fluid of the test bath.  
Damage may occur to the unit and the warranty 
would be void.
