2.6. Restriction of Record Duration
A restriction has been set on the operating duration to avoid possible damage to the camera head
caused by heat built up around the imaging sensor within the camera head when operating at
framing rates of 3,000 FPS or higher.
The framing rate automatically switches down to 250 FPS after certain a time has elapsed
operating at higher framing rates. Leave the camera idling for a while to let it cool down before
starting it at a higher framing rate again. The restriction time to each high framing rate is as
follows:
Framing Rate Restriction Time
3,000FPS: 20
minutes
5,000FPS: 10 minutes
10,000FPS: 5 minutes
The remaining current restriction time is confirmed in the ‘Record rate Restriction Time‘ box in the
‘More’ menu as shown below:
Caution: The Restriction Time feature can be switched off by removing the check
in the [Enable restriction] box making it possible to operate the camera without
time restriction at higher framing rates. However, the performance is not
guaranteed when the camera is operating at a higher framing rate out of time
restriction. Because the camera head gets very hot, you must be extremely
careful when touching it for any reason. Also, the high heat may damage the
camera head. It is highly recommended to use the camera in the Restriction Time
mode at framing rates of 3,000 FPS or higher.
Note: The Restriction Time is set ON by default: the PCI R2 system has been so designed that,
even if the Restriction Time feature is switched off, every time the frame rate is changed or the
software is restarted, it is automatically switched back to ON status.
