6.
Turn on the
T° HOLD
®
. Allow the unit to operate for a minimum of one (1) hour
before verifying the temperature.
7.
After the allotted time, the temperature reading on the Fluke Thermometer should
be within one (1) degree Celsius (two [2] degrees Fahrenheit) of the factory preset
temperature.
8.
If the two temperature readings are within one degree (1) Celsius (two [2] degrees
Fahrenheit) of each other, the temperature controller has been verified. If they are
not, please contact Medical Solutions, Inc., at 800-435-7600.
