Log Wavelength Scale
Toggles the wavelength axis of the absorption plot between log and linear scale.
% Absorption Plot
The absorption curve of the sensor versus wavelength. This data is used along with the
calibration wavelength and the user's laser wavelength to calculate the wavelength
correction factor.
Max Energy Reading (J)
The maximum energy that the instrument can read before the internal circuitry is
saturated. The instrument ranges are fixed in decade intervals, so if the maximum energy
is 15mJ, the maximum available range will be 20mJ, but the instrument will only read up
to 15mJ in that range.
Note that the maximum energy is dependent on the sensor responsivity. Since the sensor
responsivity varies with wavelength, turning Wavelength Compensation on may cause a
rescale of the available ranges. If this occurs, the maximum energy will also change.
User Probe Cal
This control calls a VI that allows the user to set a specific wavelength response for the
probe in use. The response will be stored in the probe memory. This allows for a user
calibration of desired wavelengths. Wavelength Correction must be set to ON for this VI
to work correctly. Make sure the instrument is correctly set up for measurements and is
triggered before calling this VI. Use the Live Mode if necessary to ensure this.
