- Measures a diaphragm operating time and an error of a diaphragm.
Time until it goes into the range of the iris diaphragm specified from the trigger (ms),
And the iris diaphragm error (ΔEV) of the specified time (time to be stabilized) is analyzed,
A digital display is carried out.
Drive a diaphragm from the outside.(optional)
Measurement with various postures is possible.

- Lens iris diaphragm dynamic characteristics automatic measurement for single lens reflex cameras
- All iris diaphragm angle is set up and it is automatic measurement about dynamic characteristics.
- It is logarithmic transformation about moving time of an iris diaphragm, and change of the iris diaphragm quantity of light.
- It changes into the wave of 1 [EV]/Div, and is made graph
- A setup for standard, and control a display of a measurement wave by PC.
