NOTICE

●

When firing the flash, if the flash brightness is significantly lower than the

ambient light, the meter may fail to detect the light.

Rapid start fluorescent lamps and special lighting are sometimes mistaken for

flash and accidentally measured.

Even if the flash is not fired, when a sudden light change occurs in the light

receptor, measurement may be made.

The waveform of a flash bulb has a slight slope and there is a possibility that the

light meter cannot recognize the flash bulb in Cordless Flash Mode

● The EV scale cannot be displayed in this Measuring Mode.

NOTE

●

In the Cordless Multiple (Cumulative) Flash Mode, the backlight of the LCD screen dims

and is only illuminated for three seconds after measurement.

●

After the measurement, the meter enters the 90-second Standby Mode again. If you

need to measure again, fire the flash during this time.

●

If the measured values are stored in the memory, the Measurement Standby Mode is

canceled.

●

If the icon stops blinking before the flash fires, repeat Steps 6 and 7.

●

To stop the Standby Mode, just touch the screen.

●

It is convenient to set the light meter in a fixed position during the measuring time. This

can be accomplished by mounting the meter on a tripod or stand using the tripod socket

on the bottom of the meter.
