5. Measurement
NOTE:
The flash unit may flash when you connect the synchro cord or operate the POWER
switch.
• When firing a flash to make measurements, check the camera's synchronizing range
and set the proper shutter speed.
For flash units with low electric trigger voltage, the flash may not fire. In this case, make
measurements in flash mode without cord (see page 15).
A new converted f stop is displayed when the film speed is changed after taking the
measurement.
If the shutter speed is changed after measurement, the number of cumulative flashes
and the f stop value are cleared to 0 and you must take the measurement again.
Reference:
Setting the shutter speed as measurement (see page 14) of "Flash mode with cord" of
Section 2-1.
Readings over and under the measuring range, are the same as measurement (see
page 14) of "Flash mode with cord" of section 2-1.
2-4 Cordless flash cumulative mode
These measurements are used when the light generated by the flash is inadequate for proper
exposure. The repeated flash pops can be accumulated until the desired aperture is displayed.
The accumulation can be repeated up to nine times.
1. Slide DIP switch to MULTI (see page 8) to the ON
position.
2. Hold down the Mode set button 10 and turn the
Set/change dial 5 to select flash measurement
without cord cumulative measurement mode. (MLT
will display on the LCD).
Turn the Set/change dial to set shutter speed. When
setting shutter speed, first change the settings to
confirm that they correspond to the settings available
on the camera.
3. When the light from the flash is received, the measured value (f stop) is displayed. Each
time this is repeated, the accumulated value for the aperture and the number of
cumulative flashes is displayed.

5. Measurement
4. The ready to measure mode will be displayed for approximately 90 seconds. If the 90
second period is exceeded and the blinking mark stops, press the Measuring button 19
again. The measured value (f stop) of the previous time reverts to 0 and the meter is in
ready to measure mode.
NOTE:
If the shutter speed is changed after measurement, the (f stop) value and the number
of cumulative flashes are cleared to 0 and you must take the measurement again.
When firing a flash, if the flash brightness is low compared to the ambient light, the
meter may fail to detect the light. In this case, make measurements using the flash
with cord mode.
Rapid start fluorescent lamps and special lighting are sometimes mistaken for flash
and accidentally measured. In this case, make measurements using the flash with
cord mode.
Reference:
Setting the shutter speed is the same as measurement (see page 14) of "Flash mode
with cord" of Section 2-1.
"E.u" (Exposure under) or "E.o" (Exposure over) appears when the combination of
shutter speed and aperture is not possible for the measured light level. Change the
shutter speed with the Set/change dial and take measurements again.
If the "E.u." or "E.o" readout blinks, this indicates that the light level is beyond of the
measurement range of the light meter.
