Data Library
CCT = Correlated Color Temperature
Δuv = Color Shift (off of Kelvin Line)
CCi = CC Index Correction
CCCF = CC Camera Filter Correction
CCLF = CC Lighting Filter Correction
LBi = LB Index Correction (Mired)

Spectrum Mode (With Enlargement)

The Spectrum screen displays the
spectral graph for a single reading or
for continuous monitoring. Final
measurements can be displayed as a
graph and data or graph in full screen

Flash Measurement
The C-700R is the only field spectrometer designed to measure flash color for image capture color data is displayed in Kelvin with Mired and CC values, spectrum graph and CRI, plus camera and light source filter values. Brightness is displayed in lux sec. Flash modes include cordless and triggering by PC cord.

Spectrum Comparison Mode
Spectrum Comparison creates a three light over-lay comparison with color temperature values.
Current = Spectrum
Memory 1 = Yellow Outline
Memory 2 = Red Outline

Color Rendering Index Mode
The CRI (Color Rendering Index) displays General CRI (R1-R8), Rendering Index Average (Ra, average of R1-R8) as well as Special CRI (R9 to R15) to show how accurately different colors will be reproduced.

Ra Average R1 - R8

Camera Filtration and Light Filtration Modes
Color Touch Screen Displays: Kelvin, Filter Brand, Mired, Camera or Light-Source Light Balancing filter, CC Index and Magenta/Green Camera or Light-Source filter. Filters are displayed in both common names and specific Rosco, Lee, Wratten and Fuji filter values.

Precise measurement

Multi Lights Mode
Multi Lights Screen creates a four-light Comparison. Selecting Main light adjusts other light filtration to match Main light.

Touch the Measurement button to see full screen Data for a single light.

Touch the Radio button to create “Main” light with automatic balance Information.
Precise measurement

White Balance Correction Mode
Displays the difference between the current measurement value and the target color temperature in a white balance correction graph that corresponds to color balance tools used in many DSLR and video cameras.
Precise measurement

Custom Settings Mode
You can customize the C-700R display to your operating preferences. The current setting for each item is displayed in yellow letters on the setting button.


C-700R Series Utility (software)
