Thermometer Calibration: The chamber must be stabilized at a desired
temperature before calibrating.
Place a certified thermometer (mercury in glass type) into a beaker filled
with glycerol. Position the beaker on a shelf approximately in the center of
the chamber. Allow the glycerol to equilibrate at the chamber
temperature before reading the thermometer. If the dial thermometer
reading differs from that of the certified thermometer, adjust as follows.
Gently pry the retaining ring off the dial thermometer. The ring holds
the thermometer glass in place. Adjust the calibration screw located on
the dial face to allow the two thermometers to agree.
Refrigeration Service: If it is ascertained, after review of the
Troubleshooting section, that refrigeration service is needed, contact the
Technical Services Department.
In any communication with Thermo Fisher Scientific, include the catalog
and serial numbers from the nameplate located on the rear of the control
compartment.
