With the scan disabled the dry-well heats or cools at the maximum possible rate. 6.3.1 Scan Control The scan is controlled with the scan on/off function that appears in the main menu after the temperature scale units.
6 Controller Operation Temperature Display Hold CAUTION: Do not apply any type of voltage to the display hold terminals. Applying a voltage to the terminals may cause damage to the controller. 6.4.1 Switch Status Connect the thermal switch to the display hold terminals on the either the hot or cold side. To enable the Switch Status while displaying the temperature, press "UP" on the hot or cold side.

7 Digital Communication Interface Serial Communications 7 Digital Communication Interface This instrument is capable of communicating with and being controlled by other equipment through the digital serial interface. With a digital serial interface, the instrument may be connected to a computer or other equipment. This allows the user to set the set-point temperature, monitor the temperature, and access any of the other controller functions, all using remote communications equipment.
9011 Dual-Well Calibrator User’s Guide down “SET”, then release both buttons to enter the secondary menu. Press “SET” repeatedly until the display reads “PAr”. Press “UP” once, the serial interface menu is indicated with “SErIAL”. Finally press “SET” to enter the serial parameter menu. In the serial parameters menu are the baud rate, the sample period, the duplex mode, and the linefeed parameter. 7.1.2.
7 Digital Communication Interface Interface Commands 7.1.3 Serial Operation The serial communications uses 8 data bits, one stop bit, and no parity. The set-point and other commands may be sent via the serial interface to set the temperature set-point and view or program the various parameters. The interface commands are discussed in Section 7.2. All commands are ASCII character strings terminated with a carriage-return character (CR, ASCII 13). 7.

8 Test Probe Calibration Calibrating a Single Probe 8 Test Probe Calibration For optimum accuracy and stability, allow the calibrator to warm up for 10 minutes after power-up and then allow adequate stabilization time after reaching the set-point temperature. After completing the test probe calibration procedure, allow the well to cool by setting the temperature to 25°C for one-half hour before switching the power off.
9011 Dual-Well Calibrator User’s Guide Speeding up the calibration process can be accomplished by knowing how soon to make the measurement. It is recommended that typical measurements be made at the desired temperatures with the desired test probes to establish these times.
9 Calibration Procedure Calibration Procedure 9 9.1 Calibration Procedure Calibration Procedure Calibration of this instrument should be performed at regularly scheduled intervals by qualified authorized personnel in accordance with your company’s policy. The following is provided as a basis for developing your own procedure for calibrating this instrument. 9.1.
9011 Dual-Well Calibrator User’s Guide 46 3. Set the set-point to 100°C and allow adequate time for the block to reach this temperature and stabilize. Adjust the ALPHA calibration parameter (see Section 6.14.3) to make the block temperature as measured with the standard thermometer match the set-point. The approximate ratio between a change in ALPHA and a change in temperature at 100°C is about 0.00004 to 1. For example, if the block temperature is high by 0.1°C at 100°C, decrease ALPHA by 0.000004. 4.
