-Manual adjustment-
Setting value 82000xxx h	xxx: (HV-F22) 7C5h to B6Ch / (HV-F31) 789h to B27h

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).

•Cause of shutter speed ≦ (1 / OFF_SPEED)

a)Setting value obtained from fluorescent time.

nnnh = 800h + log0.99( OFF_SPEED×”Shutter Speed”)

b)Fluorescent time obtained from setting value.

Shutter Speed[sec] = OFF_SPEED × 0.99(nnn―800h)

Ex. 1 Fluorescent time with HV-F31 = setting value nnn to obtain 1/100 second. 800h+ log0.99(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.
