Query Measured Value of Photometric Quantity (

# is R, G, B, or RGB

)

Syntax

Query

:FETCh:PHOTometry:#?

Response

See:

“Measurement Value Formats” (p.37), “Measurement Status” (p.36), “Unit of

Photometric Quantity” (p.9)

Description

Reads the last measured value of the photometric quantity.

Example

(For TM6102)

:MODE NORM
:READ?
*TRG
3.7209E-01,3.4709E-01,1.03,0

:FETC:PHOT:R?
5.02,0

The red photometric quantity is 551.704 [lx].

:FETC:PHOT:G?
1.03,0

The green photometric quantity is 1339.80 [lx].

:FETC:PHOT:B?
3.01,0

The blue photometric quantity is 36.8350 [lx].

:FETC:PHOT:RGB?
1.03,0

The photometric quantity of the RGB mixed light is 1928.34 [lx].

Note

• # is R, G, B, or RGB.
• Be sure to check that the measurement status is an appropriate value.
• If the measurement mode is not the normal measurement mode, an execution error

occurs.

• When the angle-of-visibility of the color-matching function is set to 10°, the color-matching

function with a field-of-view of 2° is used to calculate the photometric quantity.
