intensity. Auto-integration will max out at 2 sec. For integration times greater than 2 sec, toggle Auto-Integration off and

enter the desired time in the spin ctrl box. The Apogee Visible and NIR sensors support 0.005 - 10 second integration times.

The last scans integration time will be displayed in the status bar at the bottom of the screen.

regardless of the Integration Range values. These controls are inactive for the other plot modes.

Integration Time: This specifies the time frame the sensor is to use for integrating the received

radiation. A longer integration time will give a greater signal. If the auto-integration toggle

button is pressed, the device will specify its own integration time based on the received light

Number of Scans to Average: This tells the device how many measurements to average

together before outputting data.

Relative: Plots wavelength intensity as raw digital counts.

Reflectance/Transmittance: Plots the reflectance or transmittance of a material. First requires

Energy Flux Density: Plots in units of Watts/m

total over the given Integration Range from the left panel.

Photon Flux Density: Plots in units of µmol/m

total over the given Integration Range from the left panel, as well as YPF, PPF, and PPE values.

Illuminance: Plots a weighted data range in Lux or Footcandle according to user preference.

Integration Range: These spin controls become active during Energy Flux Density and Photon

Flux Density plot modes and are used to specify a customized wavelength integration range for

the Integrated Total displayed on the plot. The YPF, PPF, and PPE values remain unchanged

Fractional Range: These spin controls become active during Energy Flux Density and Photon

Flux Density modes. A 'Fractional' ratio is displayed on the graph. This ratio is the sum of the

wavelengths specified in the Fractional Range spin controls divided by the sum of the

wavelengths specified in the Integration Range spin controls.

Axes Limits: These controls are inactive if the Auto Scale toggle button is active. The y axis has

limits of (-16383, 16383) and the x axis has limits of (300, 1120). Any value in between may be

specified with an accuracy of two decimal places.

Auto Scale: Automatically scales the plot to include all data points. Can be toggled on or off.
