8.5 Using the Motor Testing
174
Motor analysis can be performed for PW3390-03.
Use the motor analysis function to measure torque, rotation rate, motor power and slip by acquiring sig-
nals from a tachometer, torque sensor or (incremental) revolution encoder.
When the motor analysis function is installed, apply torque signals to the CH A jack, and rotary encoder
signals to CH B and CH Z jacks (isolated BNC jacks are on the rear of the instrument).
CH A, CH B and CH Z jacks are isolated to support torque meters and tachometers with different ground
potentials.
Required items: Hioki L9217 Connection Cords (as needed), input devices

To avoid electric shock and damage to the instrument, observe the following
when connecting to the CH A torque signal input BNC jack and the CH B and
CH Z rotary signal input BNC jacks.
• Before connecting, turn off the instrument and any devices to be connected.
• Do not exceed the maximum input signal ratings.
• A serious accident could result if a plug falls out and contacts another conduc-
tor during operation. Ensure that all connections are secure.
When disconnecting a BNC
plug, always grip the plug and
release the lock before pulling
it out. Attempting to pull out a
plug without releasing the lock,
or pulling hard on the cable,
will damage the connectors.

Connect the instrument and input devices
using Hioki L9217 Connection Cords.
1. Confirm the that instrument and input devices are turned off.
2. As shown in the examples on the next page, connect the output jacks on the input
devices to the instrument using the connection cords.
3. Turn the instrument on.
4. Turn the connected devices on.
