3. CALIBRATION TESTING

The Calibration Key provides a convenient means of testing the thermometer.

Calibration Key Procedure

1. Extract the probe and disconnect it from the thermometer.

2. Insert the Calibration Key (part number 01637-000) into the probe connector

receptacle on the thermometer and observe the display. The display should read

CAL for two seconds, and then go blank.

3. Insert a probe shaft into the probe storage well and remove it to initiate a

temperature taking cycle. Wait for the display test and then observe the display.

The display must read between 97.1

F and 97.5

F inclusive for the calibration of

the instrument to be correct.

4. Remove the Calibration Key and reinstall the probe connector plug.

5. Then install the probe into the probe storage well.

Note:

This Cal Key test does

not

test the probe. To do so requires the use of the

Welch Allyn Model 9600 Calibration Tester.

If the reading from the Cal Key is not within the specified range or you are having

other problems with the use of the Cal Key, refer to

Cal Key Problems

in the

Troubleshooting

section.

Model 9600 Calibration Testing Procedure

The Model 9600 Calibration Tester provides a convenient means of testing the entire

thermometer system (instrument and probe).

•

The 9600 must be warmed up and stable at one of the two available temperature

settings.

•

The thermistor based instrument under test must be in Monitor mode and no probe

cover loaded.

The probe is inserted into the small hole in the dry heat well of the 9600 and allowed

to settle for a minimum of 2 minutes to the final temperature. The reading on the

thermometer must be within the range specified on the 9600. Refer to the

Model 9600

Note:

All Welch Allyn and Diatek thermometers (thermistor and infrared ear

thermometers) can be checked in the Model 9600.
