7. Wait 5 seconds, press the thermometer measure button, and watch for the green
ExacTemp light to flash.
8. Leave the thermometer in the 9600 Plus Calibration Tester until the ExacTemp light
stops flashing and you hear a beep.
9. Remove the Braun PRO 6000 thermometer from the 9600 Plus Calibration Tester
and compare the temperature displayed on the tester with the temperature on the
thermometer's display.
If the temperatures are within ±0.2 ºC (±0.4 ºF), the thermometer is within
calibration.
10. Replace the probe cover to reset, and wait for the thermometer screen to flash three
dashes (---) alternating with "CAL."
Note
11. Return the thermometer to the dock or a flat surface and wait 1 full minute before
taking another reading with the same thermometer.

12. Test all available thermometers for calibration verification at the current calibration
set point temperature before proceeding to the next calibration set point
temperature.
13. See the 9600 Plus Calibration Tester DFU to change the set point temperature.

Perform a CO2 calibration or calibration check
You can use the etCO2 parameter advanced settings to check the CO2 sensor for proper
calibration and to calibrate the sensor when calibration is due. Check calibration helps
When using the Braun 6000 test fixture, follow the
instructions provided with the fixture to position the PRO
6000 in the test fixture.
If you are not using the Braun 6000 test fixture, ensure that
the device is perpendicular in the port, directly aligned with
the calibration tester sensor, and not at an angle or tilted.
Once the device is firmly seated, do not apply additional
pressure. Doing so may cause your hand to waver and tilt or
move the device during testing.
Replace the probe cover before each reading to remove any
residual heat absorbed from the 9600 Plus Calibration Tester.
Repeated measurements in short sequence might cause
higher readings.
Holding the thermometer could raise the temperature of the
thermometer. Put the thermometer down while waiting so
that the thermometer remains at ambient room temperature.
The device will exit CAL mode after 10 minutes of inactivity or can be
forced to exit by holding both C/F and Mem for 5 seconds. After exiting
Calibration Check Mode, the thermometer returns to Sleep Mode.
