  • Page 4: Introduction

    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.

    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.

    Welch Allyn 9600 Calibration Tester OVER-TEMPERATURE DETECTOR In addition to the READY Indicator, the 9600 Calibration Tester contains an “Over-Temperature Detector.” This is a fail-safe feature that protects the unit against over-temperature conditions, in the unlikely event that a failure should occur in the temperature-control circuitry.

    Level 1 Calibration Test is described on the instruction label on the top panel of the unit and in the following instructions. If a reading in the 9600 Tester is less than, or equal to, +/-0.3 ºF from the temperature selected on the 9600, then the instrument is within specifications and no further testing is needed.

    4. Lift the flap and insert the tip of the Model 9000 Thermometer into the large opening on the 9600 Calibration Tester until it rests on top, perpendicular to the tester.

    2. Extract the probe from its holder, but do not load a probe cover. 3. Lift the flap and insert the probe fully into the small hole in the top of the 9600 Tester (the probe will go in approximately 1 3/4"). 4. Wait 2 minutes for the temperature to fully stabilize.

  • Page 10: Level 2 Calibration Test

    LEVEL 2 CALIBRATION TEST Usually thermometer calibration will fall within the +/-0.3ºF tolerance limit when tested in the 9600 Calibration Tester. This tolerance is the result of two elements: the thermometer system contributing +/-0.2ºF, and the 9600 Tester contributing +/-0.1ºF to the test reading.

  • Page 11: Troubleshooting

    If several thermometers do not pass the Level 1 or Level 2 Calibration Tests, there is a chance that the 9600 Tester is out of calibration. There are several variables that can be checked to verify if the unit is out of calibra- tion.

The Model 9000 (InstaTemp® and ThermoGuide™) Thermometer can be placed into a special Test Mode for checking the calibration using the 9600 System. The Test Mode is entered by simultaneously pressing the PULSE, TIMER, and MODE switches and is signified by a “T”...

    ESTABLISHING A BASELINE PRIOR TO MAKING CALIBRATION ADJUSTMENTS Take 2 temperatures into the 106ºF opening of the 9600 from each of 5 different probe cover dispensers and record the readings. The 10 readings are then averaged to compute the present thermometer calibration.
