5. How to use a reflected luminance (cd/m

) meter

1. Make sure that the Index correction value (see page 24) is canceled

2. Set the meter to EV mode (DIP switch) and ISO 100.

3. Set meter for spot reading.

Choose angle setting that is best suited for your subject.

Take the measurement by looking through the viewfinder and aligning so the subject that will be

measured is inside the circle.

4. Convert the measured EV with a conversion table or calculation formula to find the luminance

(cd/m

6. How to change the compensating function

Exposure compensation can be made in precise 1 /10 step increments in a +/- 9.9 EV range. Exposure

compensation may be desired to match specific requirements, calibration to other light meters, or

setting exposure calibration in 1 /10 steps up or down from standard ISO film speeds, It may also be

desired when requiring compensation for filters, bellows extension, etc. When corrections have been

made, [+ -] is displayed on the LCD.

• Making a plus correction (making the film speed / f

stop index value higher) will result in underexposing

when taking a photograph. Hold the ISO button 11 and

the ISO 2 button 6 and turn the Set/change dial 5

counter clockwise. The +/- will appear on the upper

right part of the LCD. The index correction will change

in +0.1 EV steps up to +9.9.

• Making a minus correction (making the film speed / f

stop index value lower) will result in overexposing when

taking a photograph, Hold the ISO button and the ISO 2

button and turn the Set/change dial clockwise.

The +/- will appear on the upper right part of the LCD.

The index correction will change in -0.1 EV steps up to

-9.9.

NOTE:

• Make corrections after a sufficient number of test in actual photographic conditions, to

suit your needs.

• Corrections made effect every mode of the meter.

If recalibration has been made for specific purpose do not forget to return to original

zero settings.
