Data Entry Errors
If data is entered incorrectly while setting the temperature, press the
SET TEMP
key again to exit
the data entry screen. Then repeat the SET TEMP procedure.
Lower Temperatures
If the desired temperature setting is slightly above or below ambient, coolant must be circulated
through the cooling coil. Input/output connections for the coil are located on the upper portion of
the rear panel.
Coolant temperature must be lower than the desired CT-2000 control temperature.
Caution: Extreme temperatures or variability in the temperature of the coolant
liquid may adversely affect the CT-2000 temperature control.
Note:
If a temperature is entered that is outside the operational temperature
range of the CT-2000, a
RANGE ERROR
message appears on the LCD screen. To
correct this error, press
ENTER
and follow the prompts to enter correct data.
When the CT-2000 is controlling temperature within 1/10
th
of a degree, the LCD displays a
temperature graph in 5/100
th
degree increments at the bottom of the LCD screen. A small “tick”
mark above the graph provides a visual cue to the exact temperature of the bath relative to the
requested temperature. Refer to Figure 24.
