Welch Allyn Service Tool 3 Chapter 1 Introduction
• Perform calibration verification. The service tool can check any
system requiring calibration and, if necessary, calibrate the
monitor to match the design specifications. Calibration
verification is required to meet the periodic maintenance
requirements. This feature is not supported for all products and
requires the service tool, Gold edition, for each supported
product.
• Recover devices. In the rare case where a device can no longer
boot because of corrupted firmware, the service tool can connect
the device to Welch Allyn Technical Support to reinstall the
firmware.
• Extensible. The service tool accepts new plug-ins to support
future Welch Allyn products.
