Operating Instructions
Operating the Lamp
The following sections provide instructions on operating the D-2000 Light Source.
Starting the Lamp
Press the Deuterium On/Off switch down to preheat the D-2000’s Deuterium lamp. The bulb requires a
20 second preheating period. You must allow this warm up period in order to receive accurate data. After
the warm up period, the Deuterium lamp will illuminate.
After successful illumination, the two-color LED beneath the Deuterium On/Off switch lights up green to
indicate that the Deuterium lamp is on. Should the Deuterium lamp fail to light, the two-color LED glows
red. This indicates a malfunction of the lamp. Press the Deuterium On/Off switch again to reset the lamp.
See Troubleshooting for more information.
WARNING
Protective eyewear must be worn when using this equipment - Intense ultraviolet radiation
present.
Never look directly into the light beam, as this can cause eye damage.
Turning the Lamp Off
Turn the Deuterium lamp off by pressing the Deuterium On/Off switch.
Warming Up the Lamp
The Deuterium lamp requires 10–15 minutes of operation to reach a state of thermal equilibrium. During
this warm-up period, the intensity of the UV output power can vary substantially.
If applications require extreme intensity stability, the lamp should be warmed up for an additional 30–
45 minutes. Once warmed up for this amount of time, the lamp will reach specified drift values.
