(c) Reading Measured Values
Measurement (waits for trigger and reads the measured values)
Syntax
Query
:READ?
Response (1) Modulation Frequency Measurement (
:MODE PULSe
Settings)
<Modulation frequency(NR2)>,<Measurement status(NR1)>
(2) Dark Measurement (
:MODE DARK
Settings)
<Judgment result(NR1)>
(3) Normal Measurement (
:MODE NORMal
Settings)
<Chromaticity (x) of RGB mixed light(NR3)>,<Chromaticity (y) of RGB
mixed light(NR3)>,<Photometric quantity of RGB mixed
light(NR3)>,<Measurement status(NR1)>
(1) Modulation Frequency Measurement
<Frequency> = Frequency of the signal input to the SYNC terminal [Hz]
(2) Dark Measurement
<Judgment result> = 1/0 1: PASS judgment (Dark measurement is succeeded.)
0: FAIL judgment (Dark measurement is failed.)
See:
“Measurement Value Formats” (p.37), “Measurement Status” (p.36), “Unit of
Photometric Quantity” (p.9)
Description
Changes to the trigger wait state, then reads the measured value after the measurement
has been completed.
Example
:TRIG:SOUR BUS
:PULS ON
:MODE PULS
:READ?
*TRG
60.0854,0
:PULS:FREQ 60.0854
:MODE DARK
:READ?
*TRG
1
:MODE NORM
:READ?
*TRG
3.7109E-01,3.4633E-01,4.03,0
Note
• The next command does not execute until measurement is finished.
*TRG
and
:ABORt
are received.
Please do not transmit
*TRG
and
:ABORt
at a time.
*TRG
is handled
earlier even if you transmit a message in order of
:ABORt
→
*TRG
.If you transmit both
*TRG
and
:ABORt
after
:READ?
transmission, please let weight more than 500ms enter
between
*TRG
and
:ABORt
.
• To cancel the trigger wait state, use
:ABORt
.
• Be sure to check that the measurement status is an appropriate value.
• When this command is accepted, the measured value is cleared, and then the
instrument enters the non-measurement state.
• The normal measurement and dark measurement may take some time depending on
the settings. For details about the timeout time until the response of this command is
received, see the following.
