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 long­term 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 calibra­tion, if performed within the warranty period, is free of charge. Please
contact your Welch Allyn Customer Service representative at (800) 854­2904 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 elimi­nated.

Operation Manual

MAJOR COMPONENTS OF THE 9600

TEMPERATURE SELECT SWITCH

The Temperature Select Switch and the POWER and READY Indicators are
located on the front of the Main Unit. Whenever the unit is plugged into a
standard wall outlet, the POWER indicator will illuminate. There is no
power ON/OFF switch. The READY indicator will only illuminate when the
temperature stabilizes at the temperature you have selected on the Tempera­ture Select Switch.

NOTE: For specific operational details about the components of the 9600
Calibration Tester, see the Specifications Section at the end of this manual.

POWER INDICATOR

When unpacking the 9600 Calibration Tester, notice that the Power Module
is permanently connected to the Main Unit. This is to assure a continuous
power supply to the unit, since intermittent power would cause the unit to
lose temperature control and would turn off the READY Indicator.

After the 9600 warms up, the unit will draw about 7 watts of power from a
standard wall outlet; therefore, it may be left on continuously. However, if
the unit will not be used for long periods of time, it may be unplugged.

READY INDICATOR

The 9600 Calibration Tester contains an independent temperature sensing
circuit that senses temperature changes more precisely than the thermom­eters it tests.

Because the unit contains this independent circuitry, a failure in the tempera­ture-control circuit will not alter its “READY-sensing” ability . It is virtually
impossible for the READY indicator to illuminate if the temperature is
incorrect.

NOTE: Do not use the unit if the READY indicator is not illuminated. If the 9600
does not show “Ready” within a few minutes of the time allowed in the
Specifications Section of this manual, and the environment is within acceptable
operating conditions, the unit is malfunctioning and should be returned to the
factory for repair or replacement.
