| |:::| Successful implementation of the SLICE-QTC depends critically on the design of the whole system: controller, transducer, plant, and sensor. | |
| |
| ==== Tips for Successful Temperature Regulation ==== |
| - The transducer, plant, and sensor must all be in good thermal contact. Use thermal paste or epoxy to avoid air gaps between a TEC or heater and the body of the plant as well as to secure the thermistor to the plant. |
| - Know the electrical limits of of your transducer and set the limits of the SLICE-QTC accordingly. Each channel can provide up to 6 A or 20 W of power with a maximum compliance voltage up to ~18 V. Choose transducers that work within these limits. Using the current, power, and/or voltage ratings of your transducer to calculate loads on individual channels and set limits appropriately in the CH X > Settings > Load Limits window. |
| - Maintain proper shielding of the control cable, but avoid ground loops between the SLICE-QTC and the plant. In most cases this means extending the foil shield in the cable to as close as possible to the plant without electrically connecting the SLICE-QTC to the plant. |

| ==== Extendable Legs ==== |
| The SLICE-QTC has four extendable legs (<imgref belly>). Extending the front legs allows easy viewing from above (<imgref qt_prod_shot>) and extending the rear legs (<imgref side>) allows easy viewing from below. |

It is possible to control the SLICE-QTC from a Windows<sup>®</sup>-based PC using a GUI. In order to use the GUI, you must first download the latest version, connect the PC to the SLICE-QTC, and assign a COM port to the SLICE-QTC. The following describes the steps involved. | It is possible to control the SLICE-QTC from a Windows<sup>®</sup>-based PC using a GUI.
