gown when used with the Bair Paws forced-air warming unit�
When using the Model 90055 Test Kit, take temperature readings using a calibrated
thermometer that can accept a male, subminiature connector and read a “K” type
thermocouple (e�g�, a Fluke Model 52 K/J Thermometer)� If the test unit’s connector does not
fit your thermometer, remove the connector from the test unit and attach a connector that
fits your meter� Be certain to observe polarity�
3M Patient Warming assumes no responsibility for the reliability, safety, or performance
of the Model 875 warming unit if calibration tests or adjustments are made in any
manner other than those described here� Improper measurement or adjustment of the
normal operating temperature for the Model 875 unit could result in patient exposure to
temperatures outside of the indicated range and may lead to patient injury�
