8. Press the button to measure the temperature. Record the temperature as
9. Select the appropriate correction factor from the following choices:
10. Core temperature correction: Kcore=1.087
11. Oral temperature correction: Kora=1.058
12. Rectal temperature correction: Krectal=1.095
13. The standard infrared thermometer is calibrated to indicate Core temperature, thus the
14. Calculate the display temperature according to the following formula:
Temperature displayed by thermometer is 100.9 °F, and calculated temperature is
100.9 °F, the accuracy has been verified.
Temperature value deviations: The calculated value is a function of the accuracy of the
water bath temperature. As an example, a ±1% reading error of water temperature will
result in a ±1 °F reading input into the formula, resulting in a final calculated values of
99.9 to 101.9 °F.
With a display resolution of ±1 digit and an over all resolution of ±0.2 °F, the final,
calculated reading may fall between 98.6 and 102.2.

Low Battery Sensing

The low battery threshold is not adjustable. When the battery has reached the low battery
threshold, the power supply will report this condition to the CPU on the Accutorr Plus.
