Physical assessment instrument handles
Use the physical assessment instrument handles
The handles supply power to Welch Allyn 3.5V instruments. This section focuses on operation of
the handles only. Refer to the directions for use for each instrument head to use it properly.
Note Handle modules are available only in the 84- and 85-series models.
Ensure the wall system is plugged in.
1. Lift the handle you want to use from the handle cradle.
The instrument will automatically power on when you remove it from the handle cradle. Only
one handle is powered at a time.
2. Attach a specula to the end of the instrument head if appropriate.
3. Adjust light output by turning the rheostat on the handle.
• Turning the rheostat clockwise increases the light output.
• Turning the rheostat counterclockwise decreases the light output.
Note The rheostat does not power down the instrument when you turn it
counterclockwise as far as it will go.
4. Follow the directions for use for the instrument head when examining a patient.
CAUTION Do not overstretch the cords on these handles to
prevent damage. Always examine patients within a comfortable
reach of the wall system to protect the cords.
