Page 10: Appendix 1: Computer Control
Appendix 1: Computer Control The qpod 2e responds to the same text commands as the other temperature controllers from Quantum Northwest, although obviously some related to sample changing or reference controllers are not functional. This is the complete software specification. - Page 11 Stirrer [F1 SS +] Turn stirrer on (stir rate must be set manually). [F1 SS -] Turn stirrer off. Temperature Control [F1 TC +] Turn temperature control on. [F1 TC -] Turn temperature control off. Target Temperature [F1 TT S 23.10] Set target temperature to 23.10 ºC.

Page 14: Appendix 2: Q-Blue Program Commands
Appendix 2: Q-Blue Program Commands In addition to the controller commands of Appendix 1, Q-Blue provides the following functionality. 1. Enables generation of a temperature ramp at a user specified rate. 2. Maintains records of temperature as a function of time for the sample holder and for the thermistor probe (and also for the reference holder for the dual controller). - Page 15 [*WPT>=#] - Wait until the probe temperature exceeds or equals a particular value (# as an integer). [*WPT<=#] - Wait until the probe temperature decreases to or below a particular value (# as an integer). The probe temperature is the reading of the standard 400 series or 500 series probe plugged into the temperature controller.
- Page 16 Warning Control commands [*E+] or [*E-] - When a script is running, attempting to use certain of the buttons or other controls in the main window will cause the appearance of a dialog box asking if you are sure you want to send the associated command (thus changing the series of actions defined by the script).
- Page 17 Miscellaneous commands [*R] - This program command is used only at the end of a script. It will cause the script to be repeated, starting at the beginning. [*P] - If the plot window is displayed while a script is running, the data in the plot will not be automatically updated unless a delay (*D) or wait (*W) command is being processed.

Page 18: Appendix 3: Example Script: Temperature Ramping
Appendix 3: Example Script: Temperature Ramping The following is an example of a script file. Scripts may be used to automate complex functions such as the three-old ramping illustrated here. Any text that is not enclosed by square brackets ( [ ] ) is completely ignored by the script processor, permitting the extensive commenting. - Page 19 Ramping rate will be 0.2 °C/min (0.04 °C/ 0.2 min). [F1 PA S 0.5] Set Automatic Probe temperature report to every 0.5 °C. [F1 TT S 45.00] Set Target Temperature to 45 °C to start ramping process. [*WRP>=45] Wait until the ramp parameter reaches 45 °C. [*D 200] Wait 2 minutes for probe temperature to catch up.
