INTRODUCTION
WHAT THE 9600 CALIBRATION SYSTEM IS
The 9600 Calibration Tester is a device for testing the calibration of
Welch Allyn thermometers. The unit contains solid-state circuitry for long-
term stability, with virtually no maintenance.
The 9600 System provides a convenient “reference patient” for testing the
calibration of:
n Thermistor-based thermometers (for example, Models 500, 600,
650, 678, 679, 767T, SureTemp® and SureTemp4®).
n Infrared-technology Model 9000 and Model 9020 Welch Allyn
thermometers.
To maintain long-term stability, as well as to ensure strict control over
varying environmental conditions, only the highest precision components
are used in the construction of the 9600 System. For this reason, the
instrument must be factory calibrated on a regular basis. The initial calibra-
tion, if performed within the warranty period, is free of charge. Please
contact your Welch Allyn Customer Service representative at (800) 854-
2904 for further information.
WHAT THE 9600 CALIBRATION SYSTEM DOES
The 9600 Calibration Tester provides a tightly regulated temperature source
that is compatible with all Welch Allyn thermometer products. The device’s
“temperature” can be taken with the knowledge and assurance that precise
readings will be obtained as the unit is factory calibrated to very close
tolerances. User adjustments are not required or recommended.
With the 9600 System, the difficult and time-consuming setup, precision
calibration, and maintenance requirements of water baths and other general
purpose equipment, such as ovens and environmental chambers, is elimi-
nated.
