Temperature
Perform one of the following temperature tests.
Testing the Monitor Only
Use this procedure to test only the temperature function.
1. With the temperature probe in the well, disconnect the probe cable from the temperature
input connector on the rear of the unit.
2. Connect the Welch Allyn Sure Temp Plus temperature test key (06138-000) to the
temperature input connector.
3. Remove the probe from the well.
4. Verify that the displayed temperature is 97.3 ± 0.2 °F (36.3 ± 0.1 °C).
Testing the Probe with the Monitor
Use this procedure to test the temperature function while verifying the temperature probe.
1. If the Welch Allyn 9600 Calibration Tester (01800-200) is not already warmed up, warm it
up as follows:
a. Set the 9600 Calibration Tester temperature switch to 96.4 °F (35.8 °C).
b. Plug the power adapter into the 9600 Calibration Tester; wait (up to 15 minutes) until
the tester ‘ready’ indicator light is on continuously.
2. Set the monitor temperature mode to Monitored.
3. Insert the temperature probe (without probe cover) into the small thermometer hole on
the dry-heat well of the 9600 tester.
4. Wait two minutes and verify that the reading displayed on the monitor is 96.4 ± 4 °F (35.8
± 2 °C).
5. Switch the 9600 Calibration Tester to 106.0 °F (41.1 °C) and wait about five minutes for
the ‘ready’ indicator to light.
6. Verify that the reading displayed on the monitor is 106.0 ± 0.4 °F (41.1 ± 0.2 °C).
7. Remove the probe from the tester and replace it in the probe well.
8. Disconnect the 9600 Calibration Tester.
