Figure 6. 9600 Plus Calibration Tester with the Braun ThermoScan
Pro 6000
A Braun Pro 6000 Calibration Fixture (material number 411690) is
available for use with older 9600 Plus calibration testers where
the dust cover screw might interfere with the proper alignment
of the Braun 6000 in the ear device port.
The older models have a dust cover screw that rises above the O-
ring washer. Newer models have a dust cover screw that is
recessed into the washer.
When using the calibration fixture, follow the instructions
provided with the fixture to install it to the calibration tester.
To begin calibration verification of the thermometers:
1. Check the probe tip lens window for displacement. There
should not be any gap in the seam formed between the bezel
and the lens window. If there is a gap, the unit is damaged
and must be replaced.
