Fixed averaged value
Current measurement value
(In AMBI mode, measurements
are made continuously while the
measuring button is pressed. The
positions of the pointers change
accordingly.)
This shows that the currently
measured area is 0.5 stops
brighter than the fixed averaged
value.
(In AMBI mode, measurements
are made continuously while the
measuring button is pressed. The
reading on the digital readout
changes accordingly.)
Current measurement value
(Measurement value when
measuring button is released)
Fixed averaged value
The display reverts to the fixed
averaged value.
When you release
the measuring button:

Take two readings and
store them in memory,
then press the S/A/H
button.
● turns on and the averaged
value is displayed on the digital
readout and fixed. (In this case,
the fixed average value is
F8.0+0.0-stops.)

Press the measuring
button to take a reading of
the area whose brightness
you want to compare with
the fixed value.
In AMBI mode
● Pressing the measuring button
takes continuous readings. As
each reading is taken, the
exposure difference between
the current measurement value
and the fixed averaged value of
step 1 is displayed. When you
release the measuring button,
the averaged 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
measurement value and the
fixed averaged value of step 1
is displayed. When you release
the measuring button, the fixed
averaged value of step 1 is
displayed again. (The data
panel display is the same in
AMBI mode.)
