| After making all the necessary connections you will need to find spectroscopy. This can be done by enabling the laser through the ICE CS1 menu and setting the **Laser Current** to a value which gives the desired output (see <imgref step_1>). From there, modify the setpoint temperature of the QT1 card to the temperature specified in your D2-100's 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. | After making all the necessary connections you will need to find spectroscopy.

| If your D2-100 documentation is unavailable, start by setting **Stage 2** to 15°C, engage the servo, then increase it 0.5°C at a time until spectroscopy is found or 30°C is reached. Assuming that **Ramp** is enabled, and the value of **Range** is non-zero, this should be a reliable method to find spectroscopy. | If your D2-100 documentation is unavailable, start by enabling the **Ramp**, then setting **Stage 2** to 15°C, engage the servo, then increase it 0.5°C at a time until spectroscopy is found or 30°C is reached.
