Setting Exposure Time Control Mode
Set the exposure time control mode and exposure time (upper limit or fixed value).
Exposure time and measuring cycle
• In "Auto" exposure time control mode, the measuring cycle twice the specified upper limit of the
exposure time is used (The measuring cycle remains the same even if the actual exposure time is
less than the upper limit).
• For the "Manual" exposure time control mode, the measuring cycle twice the exposure time is
used. If the exposure time is 250 s or less, the measuring cycle is set to 500 s.
As an example, here is an explanation of the procedure for setting the exposure time
control mode to "Auto" and the exposure time upper limit to "500 s."
