require electrical safety testing. Open case repairs of devices with an internal power supply require
the recommended testing because those devices contain the open frame power supply, and the
testing involves the manipulation of wiring that carries 120 or 240 volts AC. Welch Allyn does not
recommend HiPot / Dielectric Withstand testing because of a potential stress on the insulation
system, which could cause premature failures.
Basic functional verification
Basic functional verification checks
NOTE Calibration is available only with the service tool, Gold edition.
These tests verify basic functionality of the NIBP, SpO2, and thermometry parameters. These tests
support the requirements of routine preventive maintenance. However, they are not a substitute
for the complete functional tests available with the service tool, Gold edition. Welch Allyn
recommends using the service tool, Gold edition, to perform preventive maintenance and
verification of the device when completing a repair.
Basic functional verification tools
The list of tools below is what Welch Allyn uses to perform a basic device functionality check. Most
facilities use a device simulator or equivalent products to perform this test.
