- | After making all the necessary connections you will need to find spectroscopy. This can be done by modifying the setpoint temperature of the QT1 card to the temperature specified in your lasers documentation. To do this, first ensure that the **T Min** and **T Max** temperatures are configured to safe values for your system, then click on the **TSet(C)** field to enter a new value with the keyboard. For the D2-100 it is recommended to set **Stage 1** (Top) to 25°C, and to keep **Stage 2** (Bottom) between 15°C and 30°C. It is now safe to enable the laser on the CS1 card. | + | After making all the necessary connections you will need to find spectroscopy.

- | If using a D2-100 DBR laser purchased from Vescent, refer to the documentation which came with the laser to find the approximate **Stage 2** setpoint. Once the desired value is entered, click the **Servo: Off/On** button to engage the temperature servo. The **Temp(C)** field displays the measured temperature of the thermal plant, and **TError(mK)** displays the difference between **TSet(C)** and **Temp(C)** while the values are within the range of the monitor. **TError(mK)** is plotted in the graph below. | + | If using a D2-100 DBR laser purchased from Vescent, refer to the documentation which came with the laser to find the approximate **Stage 2** setpoint.

Once spectroscopy has been found, align the feature you want to lock to with the center line on the GUI plots. You can do this either by changing the **Laser Current** supplied to the diode, or by shifting the **Center** dial in the **Ramp** box. Turning **Range** up and down will make your ramp amplitude larger or smaller and show you more or less of your spectroscopy. Whatever is lined up with the center line on the plots is the feature the ICE Box will try to lock to.
