1. Memory function
This meter can store up to three measured values in memory for each measurement mode.
(incident light mode, -3 values, reflected light mode, -3 values). This feature can be used in the
following modes: ambient light (shutter speed priority only) EV, flash (with and without cord).
1. Press the Measuring button 19 and take a measure-
ment.
2. Press the Memory button 14 placing the measured
value in memory.
The number of values in memory is displayed on the

value is displayed in the analog section. By repeating
this operation, up to three values can be stored in
memory.
• Memory can be cleared by pressing the Memory clear
button 13 or changing measurement mode.
• The memory function cannot be used in "ambient light aperture priority mode" or "flash

Ave/
r EV button.
3. Brightness difference function
This function is useful for evaluating studio lighting and checking the evenness of the lighting set-up
across the subject area.
Take a measured value at a certain point as a standard value. The difference between the standard
value and a new measured value is displayed as EV and the f-stop in analog scale.
Example of adjusting lights using brightness measurement with shutter speed priority mode.
1. Turn the Lumisphere UP/DOWN ring 1
to lower it to
the DOWN position.
2. Turn any secondary light source off. Point the
