Battery Installation
The meter is powerd by two AA alkaline batteries.
○

Remove the Battery Compartment⓱ cover by lightly pressing theridged area and sliding the cover in the direction indicated by thearrow.

○

Insert new batteries into to the Battery Compartment⓱ following
the polarity symbols.

○

Replace the Battery Compartment⓱ cover*If the meter will not be used for an extended period of time, it is recommended
to remove the batteries to avoid possible damage caused by battery leaking.

Light Receiving Method Setup
Select Incident Light Measurement or Reflected Light Measurement with Switching Dial⓲.

★Incident Light Measurement：
Incident Light Measurement are made by measuring the lightthat is falling on the subject. Position the meter near the principle point of the subject with the spherefacing the camera lens.
*Reproduction of light and dark tones will be accurate in the final image because
relectance (or the lack thereof) of the subject does not affect the reading.
*Please take care that the person holding the meter does not cast a shadow on the
Incident Sphere while taking a reading.
★Reflected Light Measurement：
Reflected Light Measurement are made by measuring the lightthat is reflected by each subject in the camera field of view. When illumination is not even within a scene,
representative readings must be made of all light and dark area and then averaged
in order to determine the proper exposure.
*The light sensors meter an average of the light received in about 30 degree fieldof view.
*If you need to take a spot measurement, move the meter closer to the subject,
being careful not to cast a shodow on the area to be measured.
*Reflectance measurements made using an 18% grey card are roughly the same as
those produced by an Incident Light reading.

Notes on Flash Measurement Mode Use
1.

The Aperture (F) displayed, whether the measurement was taken with s synch cord or not, will
display the combined value of the flash and the surrounding Ambient light.【※except FD Mode】

2.

Once the ISO is set, the calculation of the Aperture (F) and the Flash Ratio (FR) are automatically
performed when a reading is taken. 【※except FD Mode】

3.

The set Shutter Speed (T) needs to be within the flah synch speed parameters of the camera used.

4.

The flash may fire if it is turned on when the synch cord is connected to the meter’s Synch Port⓯.

5.

If the contracts of the synch cord form an imcomplete circuit, causing the flash to misfire, the meter
will display the “Waiting” message. Press the Measuring Button⓫ to clear the screen, and thencheck the synch cord connections before trying another reading.

6.

Measuring under rapid-start fluorescent lights or other special lighting may lead to false readings.
In such case, it’s best to take readings using a synch code.

7.

There may be rare instances where the screen freezes and can’t be reactivated by pressing buttons.
If that happens, remove the batteries for 15 seconds, replace them, and turn the meter back on.

8.

When metering in a bright location, the meter may not be able to detect a small amount of flash.
In such cases, it may be preferable to measure the flash by connecting a synch cord.

9.

If a flash has an extremely low synch voltage, it may not be fired by a connected synch cord. Insuch cases, it may be preferable to meter withoug a synch cord.
