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.
