Its recommended that the dynamic testing be performed directly at the motor.  Testing from the starter or motor drive can introduce external sources of interference that can adversely influence the test results.   

No.  Only the blue and yellow lead should be connected when performing the DF test.  DF test should only be performed at the motor junction box with all power leads disconnected.  

OOR means the measurement you have just taken is “Out of Range”. Reset the instrument by pressing the left and right arrow keys together simultaneously which will take you back to the main menu. Ensure incoming motor test leads are disconnected and only the Blue and Yellow test leads are attached between the instrument and the motor. Retest. If you see this message again, then likely the cause is the measured value is outside the measuring range of the instrument. Or it can be caused by external sources such as energized cables, retained energy in the motor, etc. Please refer to the instrument manual for details regarding measuring range and accuracy.
