Prior To Calibration Adjustment; Establishing A Baseline Prior To Making Calibration Adjustments - Welch Allyn 9600 Operation Manual

The Test Mode will remain on as long as the "pulse timer" is active. Once in
the Test Mode, the mode may be extended by repeatedly pressing the
PULSE TIMER switch only. The Test Mode is exited automatically when
the "pulse timer" times out. The thermometer mode will then change back
to the thermometer mode prior to entering the Test Mode. The Test Mode
may be exited before the "pulse timer" times out by pressing the MODE
switch only. This will cause the thermometer mode to change to the ORAL
mode.
NOTE: For thermometers having serial numbers less than 25000, the Test
Mode is entered as an Operation Mode by repeatedly pushing the MODE
switch. For these thermometers, the Test Mode will remain until the mode is
manually changed - it will not automatically change back to the previous mode.

PRIOR TO CALIBRATION ADJUSTMENT

The sensor lens must be absolutely clean. If the lens is not clean, perform
the following cleaning procedure twice prior to calibration:
Using a cleaning swab slightly moistened with isopropyl alcohol,
clean the surface with a gentle circular motion. Immediately wipe the
lens with a clean, dry swab using the same circular motion.
After cleaning the lens, allow at least 60 minutes for the sensor to
stabilize before taking temperatures with the thermometer.
Set the Model 9600 Calibration Tester to the 106ºF position.
Set the thermometer to be adjusted to the Test Mode (T) and Fahren-
heit (F) display.
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.
