Test each probe at the low, medium, and high set points on the tester. Repeat the procedure for
each thermometer and temperature to test.
Set up the 9600 Plus calibration tester
Place the tester on a level surface away from sunlight, drafts, and other sources of heat or cold.
The tester takes approximately 20 minutes to heat to the lowest set point.
To expedite testing, Welch Allyn recommends the following practices:
•
To eliminate waiting for the tester to heat to the next set point, use three testers, each set to
one of three different set points.
• When using only one tester to test several thermometers at all three temperatures, test all
thermometers at one set point before proceeding to the next set point.
• To eliminate waiting for the tester to cool down, start at the lowest set point. Because the
tester does not have an internal fan, it requires more time to cool down than to heat up.
Change the 9600 Plus set point
To scroll from one set point to the next, press and hold the Temperature Selection button until a
beep sounds.
The new set point appears in the upper left corner of the display. The device’s current temperature
appears, flashes, and continues flashing until the cavity reaches equilibrium at the new set point.
The 9600 Plus beeps when the set point is reached.
Perform a SureTemp temperature probe and system test
1. Set the 9600 Plus to the desired set point and wait for the display to stop flashing.
2. Insert the temperature probe, without a probe cover, into the thermistor device port on the
tester.
3. When appears on the display, touch it to switch to Direct mode.
4. Wait for up to two minutes for the temperature reading to stabilize.
5. Record the results in the temperature service record.
6. Return the temperature probe to the probe well on the device.
7. Repeat the procedure as necessary until all thermometers are tested at each temperature.
To record the results of your test, go to "Service record."
