(MOTOR/AUX SET)
Press MOTOR/AUX SET to display a setup dialog box for the installed option.
Models with the Motor Evaluation Option
The MOTOR Settings dialog box appears.
The WT1800 can determine the motor rotating speed, torque, and output. It determines them using the
revolution sensor signal, which is proportional to the motor rotating speed, and the torque meter signal, which is
proportional to the motor torque. You can configure the WT1800 to receive analog (DC voltage) signals or pulse
signals from the revolution sensor and torque meter. Also, you can set the number of motor poles and determine
the motor’s synchronous speed and slip. Furthermore, you can use the active power, frequency, and motor
output measured by the WT1800 to compute the motor efficiency and total efficiency.
For a list of the measurement functions that can be measured with the motor evaluation feature and their
descriptions, see “Motor Evaluation Functions” under “Items That This Instrument Can Measure.”

*
• Motor efficiency and total efficiency computation
* This item is available on models with the harmonic measurement option or the simultaneous dual harmonic
measureme
nt option.
Scaling Factor (Scaling)
Setting the Scaling Factor for Scaling the Revolution Signal
You can set the factor for scaling the revolution signal. Set the factor to a value from 0.0001 to 99999.9999.
• When the Revolution Signal Type is Analog
This setting is used as the scaling factor in the equation for the linear scaling of analog input.
• When the Revolution Signal T
ype is Pulse
This setting is used as the scaling factor in the equation for the number of revolution signal pulses per
revolution.
