Page 24: Figure 16: Filling The Bath
The bath must be placed in its intended final position before adding Caution: bath fluid. Never move the CT-2000 when filled with bath fluid. Never use flammable bath liquids. Warning: 1. Make sure that the instrument power is OFF and select a bath liquid appropriate to your operating temperature range. -
Page 25: Drain The Bath
Warning: higher temperatures (100 °C to 150 °C). The bath liquid expands as the temperature increases. The CT-2000 bath jar is not designed to contain liquid under pressure. If the bath is overfilled the liquid may overflow and damage equipment. -
Page 26: Bath Operation
Cold Start The Cold Start is the normal start-up mode for the CT-2000. During the Cold Start process, the CT- 2000 performs several diagnostics (see Self-Test Sequence). At the conclusion of a successful test procedure, the results are briefly displayed on the LCD screen. The bath heaters are activated and the Bath Unit begins controlling the temperature according to the most recent temperature entry. -
Page 27: Warm Start
Warm Start condition and no further action is required. 4. If the bath continues to enter the Warm Start condition, consult CANNON for further assistance. Self-Test Sequence The CT-2000 start-up includes a self-test procedure encompassing key components of the system. -

(unacceptable input), such as a temperature value outside the range of the unit. ENTER ENTER button is the most-used feature on the CT-2000 keypad. Each menu choice and numeric input must be confirmed by pressing the button. -
Page 32: Data Entry Errors
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. Extreme temperatures or variability in the temperature of the coolant Caution: liquid may adversely affect the CT-2000 temperature control. -
Page 33: Calibrating The Ct-2000
Calibrating the CT-2000 The CT-2000 has the ability to be calibrated to a temperature reference standard for any desired temperature, Celsius or Fahrenheit. The controls for entering the target (desired) temperature and the calibration at this temperature are convenient and largely intuitive. The instrument stores calibration corrections for every temperature integer. -
Page 34: Calibration Theory
This calibration adjustment value for the bin is effective at all temperature ranges within 0.5 degrees of the temperature integer. The CT-2000 combines user calibration input with readings obtained by the temperature probe and data from the general bath offset, a protected menu option, which is preset at the factory by Cannon Instrument Company (see the MENU Options section for more information). -
Page 35: Menu Options
MENU Options The MENU selection from the CT-2000 keypad permits the user to access three functions: • Change to (C/F): Changes screen display to alternate temperature scale • Bath Temperature Offsets: Globally adjusts calibration data • COM Setup: Sets computer communication options... -
Page 36: General Bath Offset
General Bath Offset The General Bath Offset is a protected function of the CT-2000. This option is a global adjustment which is made at the factory by CANNON. In rare instances when this setting may need to be altered, the adjustment should be made in consultation with an authorized CANNON representative. -
Page 37: Communication Options
Change Port Speed The Change Port Speed option provides a speed setting for data transfer between the CT-2000 and a computer via the RS-232C connection. Select the baud rate (the default for most software is 9600) in bps (bits per second) from one of the following options: 1. -
Page 38: Keypad Sequence
MENU ENTER ENTER If the CT-2000 was previously configured to operate in a polled (RS-485) environment, the Communication Mode message appears on the LCD as shown in Figure 26. Figure 26: Communication Mode Display The last line on the LCD indicates that timed reports are disabled and the present mode is polled. -
Page 39: Keypad Sequence
Full Duplex (point-to-point) Connections The RS-232 interface is furnished for a direct connection between the CT-2000 and one computer. A DB-25 connector on the rear panel of the CT-2000 is configured as Data Communication Equipment (DCE). -
Page 40: Commands, Queries & Responses
Company, a disk or link will be sent to the user along with instructions on how to perform this upgrade. A download push button is located on the rear panel of the CT-2000. Pressing and holding this button for several seconds places the CT-2000 instrument in the download mode. -
Page 41: Table 3: Commands
If the command is not recognizable, ERROR is None displayed. For example, if this command is sent to a CT-2000 with an address of 5: /5CAD; then the response may be: -5CADYES Run a complete self-test like the one run at power up. A response... - Page 42 ERROR. For example, if this command requesting reports every one second interval is sent to a CT-2000 with an address of 3: /3CSR002; the response may be: -3CSRYES Set the desired target temperature of the bath as defined by the argument +&&&.&&&, in °C or °F as previously established.
- Page 43 This is followed by at least one space and then the desired temperature (to the thousandths of a degree). For example, if the following query is sent to a CT-2000 in °C with a target temperature of 40 °C and at address 3: /3QTR. This queries the temperature report.

Page 49: Appendix I: Correcting Shaft & Impeller Misalignment
Appendix I: Correcting Shaft & Impeller Misalignment Motor-stirrer units supplied by Cannon Instrument Company are checked after assembly to ensure minimum run-out (deviation from concentric rotation) at the impeller end of the shaft. The following instructions are intended to assist those who may be experiencing excessive vibration in the motor-stirrer because of shaft run-out or misalignment of the impeller blades. - Page 50 This is a trial-and-error process which usually must be repeated several times. When the crayon makes a line at least two-thirds of the way around the shaft, the run-out is diminished to an acceptable level. A uniform line completely around the shaft would indicate no run-out detectable by this procedure. CT-2000 Instruction Manual...
