After ENTER has been selected the keypad will disappear and the RUN DR will 

again be displayed.

Press START and the unit will begin the test until it is completed. When pressed the pump activates 

and starts the siphoning effect in the precipitator tube. For full suction to begin, the oil level in the 

precipitator tube must flow past the bottom of the vial in the vial holder. If this does not happen the 

viscosity of the solution is too viscous, and the PUMP button can be pressed until flow starts. The 

default for pump revolutions is set at 2 and can be changed by changing the settings in the MENU. 

Thin oil samples only need one revolution of the peristaltic pump to start the flow. Thicker oil 

samples need two or more revolutions of the pump, or heptane can be added to thin the solution.
