Operating the ISS-UV-VIS through Software
1. Connect the 15-pin accessory cable from the spectrometer to the ISS-UV-VIS.
2. Find the switch on the back of the ISS-UV-VIS. There are three positions: On, Off, and Remote. For Software
operation, move the switch to the Remote position. Moving the switch to the Remote position enables you to
control the lamp through the software, whether you are using OOIChem or OOIBase32 software.
3. When using OOIChem software, select Spectrometer | Enable Strobe from the menu to turn it on and off.
4. When you want to control the ISS-UV-VIS through OOIBase32 software, select or deselect the Strobe
Enable box in the dialog bar above the graph area to turn the bulbs on and off.
5. There can be up to a 1.5 second delay between turning the bulbs on via the software and the bulbs igniting. If
the lamp has not been used recently, the deuterium bulb may take up to 60 seconds to ignite.
6. For 0.3% peak-to-peak stability, allow 30 minutes warm-up time before taking your measurements.
Disabling the Tungsten or Deuterium Bulb
It is possible to disable the deuterium or the tungsten bulb in the ISS-UV-VIS. Both bulbs are enabled at the time of
manufacture. In order to disable the deuterium or tungsten bulb, you must remove the casing of the ISS-UV-VIS.
Disabling the Deuterium Bulb
Jumper block JA of the ISS-UV-VIS's circuit board controls the deuterium bulb. Short the pins 2-3 (that is, place
a jumper over pins 2-3 of JA) to enable the deuterium bulb. Short the pins 1-2 (that is, place a jumper over pins 1-
2 of JA) to disable the deuterium bulb.
Disabling the Tungsten Bulb
Jumper block JB of the ISS-UV-VIS's circuit board controls the tungsten bulb. Short the pins 2-3 (that is, place a
jumper over pins 2-3 of JB) to enable the tungsten bulb. Short the pins 1-2 (that is, place a jumper over pins 1-2 of
JB) to disable the tungsten bulb.
Using Solarization-resistant Fibers
For any experiments using UV light, we recommend using our solarization-resistant fiber. Our 300-µm Diameter
Solarization-resistant Optical Fiber consists of a silica core, surrounded by a silica cladding material. The fiber is
then coated in aluminum. Our solarization-resistant fibers are best used for regions below 250 nm, or where
exposure to long-term UV light occurs. If you do not use solarization-resistant fibers when using a UV light
source, the UV radiation degrades the silica in a standard patch cord fiber over time, resulting in increased overall
absorption values and invalid data.
