Operating Instructions
Operating the Lamp
The following sections provide instructions on operating the Deuterium and Halogen lamps in the DH-
2000. The Halogen lamp is only available in the DH-2000, DH-2000-DUV, and DH-2000-BAL models.
Caution
The unit must operate in a horizontal position.
Starting the Lamp
Press the Deuterium or Halogen On/Off switch down to preheat the desired lamp. The LED blinks green
until the lamp illuminates (approximately 20 seconds). 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 lamp
will light.
After successful illumination, the two-color LED beneath the lamp’s On/Off switch lights up green to
indicate that the lamp is on. Should the lamp fail to light, the two-color LED lights up red. This indicates
a malfunction of the lamp. Press the On/Off switch again to reset the lamp. See Troubleshooting for more
information.
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.
WARNING
Turning the Lamp Off
Turn the lamp off by pressing the appropriate On/Off switch.
Warming Up the Lamp
The Deuterium lamp requires 10–15 minutes, while the Tungsten-Halogen lamp requires 5–10 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.

3: Operating Instructions
10 000-10000-025-02-201510
If applications require extreme intensity stability, the Halogen lamp should be warmed up for an
additional 15 minutes. Once warmed up for this amount of time, the lamp will reach specified drift values.

Issue
Probable Cause
Resolution
Power switches on, but no
LEDs light.
Line power not present
Check line voltage
Fuse defective
Check fuse
