6. The 

WP-89

 will now allow you to enter the value of the second turbidity 

standard solution. For example… 

180.3NTU pnt2/3 

F2:OK

:set 

Press 

 and 

 to set the value of the turbidity standard solution. 

Press 

 to calibrate the second calibration point. 

Press 

 to quit and retain the current calibration. 

7. Place the probe into a the third turbidity standard solution (eg 1800 NTU). 

This must have a Turbidity value higher than the second standard. 

IMPORTANT :

 Leave at least 25mm clearance from the bottom of the 

probe to the bottom of the beaker to avoid interference with the reading. 

The reading from the probe is displayed. For example… 

  1803NTU pnt3/3 
F2:grab 

When the reading has stabilised, press 

 to GRAB the turbidity standard 

solution reading.
