Digital Camera Effective Exposure Time Tester

      The digital camera effective exposure time detector is used to detect the performance of the digital camera shutter, including shutter time (effective exposure time), exposure amount, and aperture value. The following is a schematic diagram of the working time axis of the lens shutter.

Features:
· Apertures of various aperture sizes can be tested
Step-by-step difference in light quantity can be measured (optimal for hysteresis detection)
20 consecutive tests in 1 second

Measurement items:
Boot time (T1)
Shutdown time (T2)
Effective Time Exposure (TE)
Aperture value (Av)
Different exposure values and different aperture values (Ev)
T2 (off time) detection point: 0~100%, 5~95%, 10~90%, 15~58%, 20~80%
Measuring effective aperture diameter: Φ20~Φ0.3

Measuring range:
±9.99EV (exposure error)
1~11AV (aperture value)
1~1/8000s (shutter time)

Measurement accuracy:
±0.05EV (exposure error)
±10μs (shutter time error)
±0.02EV (IRIS model aperture value error)
Power supply: AC100~240V (50/60Hz), 100VA
