Profoto Pro-7 manual Reliability Testing The R-Test

Reliability Testing - The R-Test

The Profoto R-test guarantees that all products leaving the factory meet the very high stan- dards required of professional equipment by professional photographers. The R-test is a rigorous performance test that the Profoto generators are put through - 720 full power flashes are released during one hour, which is equivalent to 20 rolls of 35 mm film.

After the test the equipment is examined to see that all parts have kept a normal operating temperature and are not malfunctioning in any way. All Profoto products are subjected to the R-test prior to being shipped.

Colour Temperature

The Pro-7 generators are perfectly suited for critical analouge (film) and digital shoots. The colour temperature is constant with a variation of a maximum of +/- 75° Kelvin.

PLEASE NOTE: combining flash tubes and/or glass covers with different coatings can make even more distinctive colour temperature adjustments.

Flash Duration

Reducing the energy output can shorten the flash duration. The shortest flash duration using a Pro-7 head and a Pro-7s/1200 generator at 1/32 energy is 1/8000 sec. (For more details please see ”Technical Data” on page 32). If a Pro-7 twin is used a flash duration of 1/12000 can be achieved with a Pro-7s/1200 unit.

Lamp Heads

The following are suited for Pro-7s 1200/2400:

ProHead [90.07.09]Pro-7 ring [30.05.15] ProTwin [90.01.19] You can also use the Pro-7 head and Pro-7 twin head.
