• Braun ThermoScan
The 9600 Plus Calibration Tester provides a tightly regulated
temperature source that eliminates the setup, precision
calibration, and maintenance requirements of water baths and
other general purpose calibration equipment. The user takes
the “temperature” of the 9600 Plus Calibration Tester with the
knowledge and assurance that precise readings are obtained
because the unit is factory calibrated to National Institute of
Standards and Technology (NIST) or equivalent devices. User
adjustments are not required or recommended.
The “blackbody” of the 9600 Plus Calibration System acts as
a heat reservoir for the thermistor probe and as a heat
radiator for the infrared ear thermometers.

Operation
9600 Plus Calibration Tester Setup
Place the 9600 Plus Calibration Tester on a level surface away
from sunlight, drafts, and other sources of heat or cold. The
9600 Plus Calibration Tester takes approximately 20 minutes
to heat to the lowest setting. When testing several
thermometers at all three temperatures, it is recommended
to test all probes at one Calibration Set Point Temperature
before proceeding to the next Calibration Set Point
Temperature. To further expedite testing start at the lowest
Calibration Set Point Temperature. The 9600 Plus Calibration
Tester does not have an internal fan, causing the cool down
time to be greater than the time it takes to heat up.

12.Wait one full minute before taking another reading with the
same thermometer. Repeated measurements in short
sequence may cause higher readings.
Do not hold the thermometer while waiting. This allows
the thermometer to remain at ambient room
temperature.
13.When using only one 9600 Plus Calibration Tester, test all
available thermometers for calibration verification at the
current calibration set point temperature before proceeding to
the next calibration set point temperature. See "Changing the
Calibration Set Point Temperature" (page 11).
14.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 will return to Sleep Mode.
