Measurement

5.  Press the START key.

The indication “RUN” appears on the display and the rotor starts to 

turn. Hold the unit steady until the viscosity indication has stabilized. 

When a stable value has been obtained, press the START key again. 

The rotor stops turning, and the measurement value remains on the 

display for easy reading.

6.  When measurement is completed, hold down the power key until the 

power is set to off (at least 1 second).

 About power swing

When the rotor starts to turn, temporary overload may cause a so-

called power swing condition where the rotor cannot turn properly. 

In such a case, the indication “FAIL” is shown on the display, the 

rotor is stopped, and then started up again.
