4.8 Viewing Motor Measurement Values (With Hioki 9791 or 9793 installed)
82
Motor analysis is available when the Model 9791 Motor Testing Option or 9793 Motor Testing & D/A Out-
put Option (afterwards called the motor analysis function) is installed.
When the motor analysis function is installed, the [Motor] page appears on the Measurement and Setting
screens.
The motor analysis function acquires signals from rotation-sensing devices such as a torque sensor and
rotary encoder and measures motor analysis items (torque, rotation rate, motor power and slip).
Motor efficiency, total efficiency and loss can be calculated when combined with the"4.7 Viewing Effi-
ciency and Loss Measurement Values" (p. 77) functions.
See Motor measurements can be displayed simultaneously with motor input voltage and current, power measure-
ments and motor efficiency. "Selecting Measured Items for Display" (p. 38)
