Electronic shutter can be set in the range of 4 to 1/100,000 second.
Shutter speed setting value can be derived as follows.
OFF_SPEED
= 15 (HV-F22), 30 (HV-F31).

(1 / OFF_SPEED)
a) Setting value obtained from fluorescent time.
nnnh = 800h + log

(
OFF_SPEED
×”Shutter Speed”)
b) Fluorescent time obtained from setting value.
Shutter Speed[sec] =
OFF_SPEED

Ex. 1
Fluorescent time with HV-F31 = setting value nnn to obtain 1/100 second.
800h+ log
0.99
(30×(1/100))
= 800h+ log(30×(1/100)) / log0.99
= 878h
Ex. 2
Setting value nnn that produces 1/100 second fluorescent time with HV-F31F.
(1/30) × 0.99
(878h
-
800h)
= 1/100(sec)
•
Cause of shutter speed > (1 / OFF_SPEED)
a) Setting value obtained from fluorescent time.
nnnh = 801h - (
OFF_SPEED
×”Shutter Speed” )
b) Fluorescent time obtained from setting value.
