HVM200 Manual Making the Measurement 3-7
Refer to the seciton "Transducer
Selection" for more information.
Step 3 Connect the accelerometer to the HVM200.
Step 4 Attach the accelerometer to an appropriate adapter.
Position for Whole Body Vibration with Seat Adapter
For whole body vibration measurements using the Larson
Davis SEN027 Seat Adapter, follow these steps:
The Seat Adapter is sold with the
SEN027 accelerometer already
housed within the adapter and with
the cable already connected to the
accelerometer.
Step 1 Place the seat adapter in the location where the
person being monitored will sit.
Step 2 Connect the accelerometer cable to the HVM200.
Step 3 Set the HVM200 meter in a secure location, where
it will not fall from its position.
Start the Measurement
Click the Start button that appears on all HVM200 App
displays.
