the current measurement value
and the fixed measurement
value of step 1 is displayed.
When you release the
measuring button, the fixed
reference value of step 1 is
displayed.
In CORD mode
● Each time you press the
measuring button, the flash is
fired and a single exposure
reading is taken. While the
measuring button is pressed,
the exposure difference
between the current

fixed measurement value of
step 1 is displayed. When you
release the measuring button,
the fixed measurement value of
step 1 is displayed again. (The
data panel display is the same
