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
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 lamp off by pressing the appropriate On/Off switch.
