■Features・Measure the operating time and aperture ratio of the lens shutter, single shutter, and aperture
・Use LS mode when measuring lens shutter or shutter alone
・Use DSC mode for measuring digital camera shutters
・Condensing lens unit is available as an option for measuring a single shutter.

Operating environment
■Main body・Temperature: 5 - 45 [℃]
・Humidity 85 [%] or less, no condensation

■Head section・Temperature: -40 - 80 [℃]
・Humidity: 80 [%] or less and +60℃ 90% non-condensing

■Measurement item: LS mode (in lens shutter measurement mode)① TE effective exposure time [time at 50% level compared to when the shutter is fully open]
② TV effective exposure time [actual effective exposure time]
TV= EV−AV (= 5−ΔEV+F1)
③ T1 Time from start to end of opening
④ T2 full opening time
⑤ T3 Time from the start of closing to the end of closing
⑥ Error of maximum aperture of F1 aperture with respect to reference aperture
⑦ Error with respect to the standard aperture after the interval setting time from the end of F2 opening
⑧ Error with respect to standard diameter at FXX contact
⑨ ΔEV Error from the standard exposure amount from the beginning of opening to the end of closing
⑩ TOT Total exposure time
⑪ Time from DT opening end to X contact
⑫ INT interval setting time display

■Measurement item: DSC mode (when measuring with digital shutter camera)① TE effective exposure time [time at 50% level compared to when the shutter is fully open]
② TV effective exposure time [actual effective exposure time]
TV= EV−AV (= 5−ΔEV+F3)
③ T4 full open exposure time [time from TRG input to start of closing]
④ T3 fall time [time from the start of closing to the end of closing]
⑤ Aperture error with respect to standard aperture when inputting F3 TRG
⑥ Aperture error with respect to the reference aperture after setting the interval time from F2 TRG input
⑦ Error with respect to standard diameter at FXX contact
⑧ ΔEV TRG Error from reference exposure amount from input to end of closing
⑨ EV2 Exposure amount from the beginning of closing to the end of closing
⑩ Time from DTX contact to start of closing
⑪ Time from TOT TRG input to end of closing
⑫ INT interval setting time display
