Battery Installation ',' !:"
The meter is powered by one 1.5 volt (size AA) alkaline battery'
1. Remove the Battery Compartment cover by lightly pressing the grooved area and sliding
the cover in the direction indicated by the arrow.
2. Insert a new battery into the Battery Compartment, (t g) tottowing the polarity symbols.
3. Raplace battery cover.
Battery Check/ Low Battery Warning
The Battery Check function is automatically engaged whenever the meter is turned on.
For approximately three seconds after pressing the Power Button (S), tne analog scaleI will indicate the voltage level of the battery. lf the voltage level of the battery drops below
minimum requirements, no level will be shown. This indicates that a new battery is required

Automatic Power Off
To maximize battery life, the meter will automatically shut down after five minutes if not in use.
The meter is equipped with a memory feature that retains all settings (lSO film speed, Program
Level, etc.) when the meter is turned off or the battery is changed.
SELECTING A MEASURING METHOD
Depending on the lighting situation and the subject being photographed, you must select either
an Incident Incident Light or Spot Light measuring methods. Following is a brief description of
each method.
I Incident Light Readings: .-l
Incident light readings are made by measuring the light
that is falling on the subject. Reproduction of light and
dark tones will be accurate in the final image because
the reflectance (or lack of reflectance) of the subject
does not affect the reading. Because the hemispherical
incident dome simulates a three dimensional subject,
incident light readings are idealfor most situations.

How to take Incident Light Readings
1. Set the Measuremenl Selector (g) to tne incident mark.
2. Turn the Spot Finder Head (1 5) 1 80 degrees to face the rear. This will prevent the Incident Sphere from being
shadowed by the Spot Lens (1).
3. Position the meter near the principle point of the subject with the Incident Sphere (Z) {acing the camera lens.
In situation where there is fairly even illumination (i.e. outdoors under clear sky), it is not crucial to position
the meter near lhe subject. The meter may be held in line with the subject with the Incident Sphere (2) facing
the camera lens.

lI Spot Light Readings:
Reflected spot Light readings are made by the average light that is reflected by each subject in the angle of 5 degrees. The spot reading is useful:
1. to get an accurate reflected light reading of a particular area of a subiect.
2. to get a rellected light reading from subiect that's far away or hard to reach.
3. to measure areas of different contrast on a subiect_
4. to get an average reading of light and dark areas.
How to take Reflected Spot Light Readings
1. Set the Measurement selector (g) to the spot Mark. 2. spot Finder Head (t s) can be at any position for readi I
3. While standing at the camera position, look
through the Eyepiece (14) and use the centering
dot to aim at the subject.
4. Area within the golden circle will be measured.
5. When measuring subjects at about t m (g.gft)
away from the meter, use the Close up Centering
Dot to determine the approximate measuring area.
* Dotted circle indicate approximate measuring area.
6. Take exposure readings based on the directions
given in the following pages:
* Make sure not case any unwanted shadows on
the subject when taking reflected spot light
measurements. Close up Centering DotView original page 10Page 11 · Read text

3. Position the meter and push the Measuring/Trigger Button to obtain a reading. The proper f/stop
for the corresponding shutter speed will be displayed. The Analog scale (directly below the f/stop)
indicates fractional readings in 1/1 0 stop increments. For shutter speeds of one second or longer,
the letter "S" will appear directly below the shutter speed value.
4. Use the Up Key or Down Key to obtain the desired f/stop and shutter speed combination.

Multiple Flash Mode
The Multiple Flash Mode is used to determine how many times the flash must be fired to obtain
a desired f/stop. This feature can be used in the Cordless and Corded Flash Modes.
1. Using the corded or cordless method, fire the flash once and obtain a readinq.
2. Press and hold the Multiple Flash Button (t Z). ffre Multiple Flash frfi! tconi,vitt appear on the

Program Level (P.L.) Feature
The Program Level feature allows you to pre-set your the meter to your preferred exposure readings.
By adjustig the Program Level, the meter will automatically adjust readings to overexpose or underexpose
by as little as a tenth of an f/stop or as much as 9/10 of an f/stop.
1. With the meter turned on, remove the Battery Compartment cover.
2. Press the Program tevel (P.L.) Button (ZO) tocated just below the battery. The Program Level lcon and
Analog Scale will appear on the LCD display.
3. White holding the Program Level button, use the Up Key (l) or Down Key (tA) to adjust the level of the meter.
A "plus" or "minus" symbol will appear in the Program Level, indicating over or underexposure, respectively.
Each symbol on the Analog Scale represents 1/10 stop.I

This feature is also useful when it is necessary to make corrections for the measurement under different
type of light source.
