About the Welch Allyn Service Tool
The service tool is required to complete functional verification and calibration tests.
The Silver-level service tool enables a calibration check to satisfy the recommended annual service.
To perform the calibration check, execute each of the Silver-level tests indicated in the table below.
A Service Record form is provided at the end of this chapter for documentation of the calibration
check results. If any of the Silver-level testing shows an out-of-specification result, use the Gold-
level service tool to perform a full calibration.
The Gold-level service tool checks the functionality and calibration of the device. As it checks the
device, the Gold tool also performs any needed calibration to bring the device within
specifications. This full suite of tests is required to complete a repair. Each time you open the case,
you must use the Gold tool to test the device before returning the device to normal use.
