Setting up the Device 

 

Prior  to  measuring,  the  device  needs  to  be  set-up.  Screw  the  rod  into  the 

base-plate  and  stand  it  on  a  stable  surface. Slide  the  sensor  head  onto the 

rod  while  pushing  the  lever  down.  Release  the  lever  once  the  desired 

position is reached. Now, conn

ect the sensor head’s pneumatic cable to the 

measuring  device.  Note  that  the  red  markings  on  both  the  plug  and  the 

socket  need  to  be  aligned.  Activate  the  power  supply  by  plugging  it  into 

mains or insert 4 mignon (AA) batteries into the battery compartment 

(watch 

for  the  right  polarisation!)

.  Additionally,  you  may  want  to  connect  the 

device  to  the  serial  port  of  your  PC.  This  can  be  done  by  means  of  the 

interface  cable  included.  Plug  the  capillary  onto  the  Luer  connector  on  the 

sensor head (slightly push and then turn right). The tensiometer is now ready 

for measuring. 

 

Inserting or Changing the Battery 

 
For inserting and changing the batteries (4 x Mignon (AA)) open the bottom 

of the device by depressing the ends of the battery box. Please take care for 

the correct polarisation. 

 

  Warning

 

  Use this device for the described 
  application only! 
  Other uses might be dangerous.
