The plate meter is supplied in three parts: 

The heavy duty plastic plate sits on top of the pasture to establish average height 
and  density.  The  area  of  the  circle  and  weight  of  the  plate  have  been  carefully 
calibrated. 

The grooved rod allows pasture to be measured in 0.5 cm intervals (clicks). The 
yellow shaft includes the electronic meter. 

The black handle can be adjusted to suit the height of the user. 

To assemble the plate meter: 
1

 

With  one  hand,  hold  the  yellow 
shaft  vertically  with  the  counter 
towards  the  ground.  The  grooved 
rod  will  slide  down  through  the 
shaft.
