Wavelength Units
Sets the display wavelength units to nm, µm, or Ang.
Angtrom (Ang) is a unit of measurement of wavelength of light and other radiation equal to one
ten-thousandth of a micron or one hundred-millionth of a centimeter.
Key Path
Zero Now
Causes the auto zero function to run immediately. This allows you to manually zero the instrument
when the auto zero function is off.
In Auto Zero mode, the instrument compensates for temperature-related current drift between
each sweep. Although this "zeroing" increases amplitude accuracy, it also increases the time
between sweeps. If amplitude accuracy is not critical to your measurement, turn off zeroing to
improve throughput.
The instrument performs a more complete zeroing when the instrument is first turned on. You can
run this more complete routine anytime by pressing the Zero Now softkey.
