10. SHUTTER SPEED SETTING AT INTERVALS OF 1 H
The shutter speed can be set at intervals of 1H (1H=63.5 ^is) only at one-pulse trigger
SYNC reset/non-reset modes. At these modes, the shutter speed can be set in the range
from 262.5H (1/60 s) to OH (1/30000 s). The shutter speed is set with S302. The mode is set
with switches No. 7 and No. 8 of S308. Then S301 is pressed once after confirming the
power is turned ON.
S308 (mode setting)
No. 7 setting: In case of 1/60 (262.5H) to 1/984.3 (16H), set at OFF.
In case of 1/1049.9 (15H) to 1/30000, set at ON.
No. 8 set at ON: When setting the shutter speed at intervals of 1H.
(Turned OFF when direct setting by means of S305, S306 and S307.)
S302 (Shutter speed data)
Set the exposure period (H) (shutter speed) as binary data of 9 bit. Set '0' at ON, and at
OFF with 'No.V side of S302 as LSB and 'No.9' side as MSB. For example, in case the
exposure period is 8H (shutter speed ranging from 1/63.5 x 8 ^is to 1/2000 s.), S302 is set
as below, since the number '8' is rewritten into '000001000' as binary data of 9 bit.
(LSB)
(MSB)
Not used.
(Be always sure to turn off)
The exposure period A(H) and the shutter speed 1/B (s) can be obtained from the follow
ing equations. The obtained exposure period A(H) is rounded to the nearest integral num
ber.
