External start measurement
When measuring the spectral of a flash lamp, laser, and other pulsed light
with this system, use the external start measurement mode. See timing
chart below.

Method
1) Connections
Input the trigger signal to the TRIG. IN terminal at
TTL/High impedance using a BNC-BNC cable.
2) Operation
Set Trigger MODE to Start and the Number of Cycle
from the application software. Next measure the
data using the data measurement function.
DATA OUT
When TRIG. IN is input, the system begins to read the sen so r after a
time delay equal to the Delay Time set by the software.
In th is meaurement, the TRIG. IN input interval becomes the sensor
exp osure time(Exposure Time).
