Turns ozone generator ON or OFF.
Functions in both ON and STANDBY modes if the pump is producing sufficient vacuum.
Display Output Controls
Controls the range of the front panel display between high sensitivity
Displays the output signal of the SCD in millivolts. (Note: Changing the output range of the SCD by adjusting the recorder switch on the back panel does not change the range of the display.)
Displays the pressure of the chemiluminescence reaction chamber in Torr (mm Hg)
Signal Controls
The SCD and NCD use analog amplifier circuitry for the measurement of the current produced by the photomultiplier tube. Two Front Panel Controls are used to adjust the output signal of the Detector.
Changes the gain of the amplifier by a factor of
100.For high sensitivity measurement of sulfur or nitrogen compounds (measurement of low levels of sulfur or nitrogen compounds), the attenuation should be operated in the 1 position. For samples containing high levels (ppm to percent) of sulfur or nitrogen compounds, use the 100 position.
