Press the appropriate keypad choice(s) firmly to make your selections. The CT-2000 signals
reception of each keypad command with a short, high-pitched beep sound. A longer beep indicates
a data entry error (unacceptable input), such as a temperature value outside the range of the unit.
ENTER
The ENTER button is the most-used feature on the CT-2000 keypad. Each menu choice and numeric
input must be confirmed by pressing the ENTER button.
Selecting Options/Cancelling Options
Press the appropriate keypad button once to access that option (SET TEMP, CAL TEMP or MENU).
If you make a data entry error and wish to cancel your input sequence, simply press the original
keypad option button again to clear data.
Note: If the keypad does not receive user input for five minutes after a primary
option is selected, the instrument returns to the LCD temperature display screen
without saving any changes.
These three buttons are the only options available when the Cold Start routine is begun—SET
TEMP, CAL TEMP and MENU:
• SET TEMP allows user to enter the desired bath temperature setting. See details below.
• CAL TEMP allows user to recalibrate the temperature sensing mechanism. See section
Calibrating the CT-2000.
• MENU allows user to change temperature scale (°F or °C), reset calibration offsets and change
other system settings (See section MENU Options).
Setting Bath Temperature
SET TEMP Procedure
1. To set the bath temperature, choose SET TEMP from the keypad after a successful Cold Start.
2. The LCD displays a message requesting input of the new target temperature. Use the numerical
keys to enter the new temperature. Enter positive numbers from 10 °C to 150 °C (50 °F to
302 °F) with up to three decimal places.
3. Press the ENTER key to save your data. The bath now attempts to equilibrate at the new
temperature.
The temperature may be reset at any time.
