Adjusting Display And Output Settings

The units of measurement displayed by the TEC 3000 may be adjusted to accommodate the needs of the user.
Temperature measurement may be displayed in degrees Kelvin (°K), degrees Celsius (°C), or degrees Fahrenheit
(°F). The amount of liquid nitrogen in the freezer may be displayed in inches (in), millimeters (mm). In addition, the
amount of liquid nitrogen consumed by the freezer (liquid usage) may be shown on the display.

Calibration of Temperature Probes

Each of the temperature sensor probes (A and B) used with the TEC 3000 have been calibrated at the factory using
the "Low Temperature Range" method. This calibration method provides a level of accurancy of +/-1.8°F (+/-1°C)
when operated in the altitude range of 1000ft. to 1500ft. (305m to 457m). Further calibration should not be required
unless desired by the end user. Refer to the TEC 3000 Technical Manual for information on calibration methods
and procedures.
