3. When the Measuring button is pressed, the
mode mark will blink and the meter is ready to
measure. The ready to measure mode will continue
for approximately 90 seconds.
During this time, trigger the flash to make a
measurement.
4. If the 90 second period is exceeded and the blinking
mark stops, press the Measuring button again to
return to ready to measure status.
5. When the light from the flash is received, the measured value (f stop) is displayed. Even
after measurement, the mode mark continues to blink and the meter is in ready state
and a new measurement can be made. (Auto-reset function)
NOTES:
• When firing a flash, if the flash brightness is 8EV lower than the ambient light, the meter
may fail to detect the light. In this case, make measurements using the cord flash mode
(see page 21).
• Rapid start fluorescent lamps and special lighting are sometimes mistaken for flash, and
accidentally measured. In this case, make measurements using the cord flash mode (see
page 21).
• The waveform of flashbulb have a slight slope and there is a possibility that light meter
cannot recognize the flashbulb in Cordless flash mode. In this case, be sure to take
measurement in Cord flash mode (see page 21).
Reference:
• After measurement, the F stop value corresponding to the shutter speed is displayed when
the shutter speed is changed.
• Setting the shutter speed is similar to the previous instruction. (see page 21) of “Cord flash
mode” of section 2-1.
• A new converted value is displayed when the ISO sensitivity is changed after taking the
measurement.
• Readings outside the display range or beyond the measuring range are similar to the previous
instruction. (see page 16) of “Shutter speed priority mode” of section 1-1.
• You can select aperture scale or EV scale by holding Mode button and pressing AVE. / EV
button.
• The meter’s tripod socket permits mounting it to a tripod or light stand and placing it strategically
when using cordless flash mode.
