For other error messages, refer to page 101.
● “NO SYNC. SIGNAL” (when EXT mode is selected)
•
Cause 1 : The vertical synchronizing signal used for the display is not connected to the terminal on the
instrument.
Action : If EXT mode is selected, input the vertical synchronizing signal to the terminal on the instru-
ment properly.
•
Cause 2 : The frequency of the vertical synchronizing signal used for the display is below 40 Hz or beyond
200 Hz.
Action : Change SYNC mode to UNIV. mode and start measurement.
Measurement Mode Description
xyLv mode
Used to display/output chromaticity coordinates xy and luminance Lv.
(The analog display section shows ∆x, ∆y and ∆Lv.)
T∆uvLv mode
Used to display/output T (correlated color temperature), ∆uv (color difference from
blackbody locus) and luminance Lv.
(The analog display section shows ∆x, ∆y and ∆Lv.)
Analyzer mode
G-reference
Used to display meeasurement RBG emission intensities as a percentage of the RGB
emission intensities target color(W). Analog display shows measured ratios R/G and
B/G, and ∆G
R-reference
Used to display meeasurement RBG emission intensities as a percentage of the RGB
emission intensities target color(W). Analog display shows measured ratios G/R and
B/R, and ∆R
u'v'Lv mode
Used to display/output u'v' chromaticity coordinates (CIE 1976 UCS chromaticity
diagram) and luminance Lv.
(The analog display section shows ∆x, ∆y and ∆Lv.)
Used to display flicker amount abtained form contrast format (AC/DC). The unit is %.
Can be selected only when LED Flicker Measuring ø27 Probe(CA-P32/35) or LED
Flicker Measuring ø10 Probe(CA-PS32/35) is connected.
Flicker mode
When the optional 4-Probe Expansion Board CA-B15 is used
Can be selected only when LED Flicker Measuring ø27 Probe(CA-P32/35) or LED
Flicker Measuring ø10 Probe(CA-PS32/35) is selected.
XYZ mode
Used to display/output tristimulus values X, Y and Z.
(The analog display section shows ∆x, ∆y and ∆Lv.)
G Standard
R Standard
