4. Basic Operation 4. When set for reflected light (spot metering) 1. This method measures the brightness (luminance) of the light reflected from the subject. It is useful for distant objects such as landscapes, when you cannot go to the position of the subject, or for metering subjects that generate light (neon signs, etc.), highly reflective surfaces or translucent subjects (stained glass, etc.). Take the measurement by aligning the circle inside the viewfinder with the subject area to be measured. 3.

Press the Measuring button ! 4 to make a shutter speed value measurement. Release the Measuring button to complete the measurement. The measured value (f stop value) will be displayed. While pressing the measuring button, the meter measures continuously until it is released.
5. Measurement 2. Measuring flash light This method of measurement can be done in the following modes; with cord, without cord, multiple flash with cord, multiple flash without cord and Wireless flash radio triggering mode (with optional radio transmitter module). When Measuring flash light, the shutter speed and F stop value (value combining ambient light and flash light: total amount of light) are displayed.
5. Measurement CAUTION: • There is danger of electric shock if the meter is handled with wet hands, during rain, in areas splashed by water or where there is a lot of moisture, if you use cord synchronized flash. • Under such conditions, it is recommended that you use the meter in the cordless flash mode or Wireless flash radio triggering mode, and keep the Synchro terminal cap in place. NOTE: • The electronic flash unit may trigger when you connect the Synchro cord or operate the POWER Switch.
5. Measurement 3. When the Measuring button !4 is pressed, the mode mark will blink and the meter is ready to measure. The ready to measure mode will continue for approximately 90 seconds. During this time, trigger the flash to make a measurement. 4. If the 90 second period is exceeded and the blinking mark stops, press the Measuring button again to return to ready to measure. Set shutter speed 5. When the light from the flash is received, the measured value (f stop) is displayed.
5. Measurement 2-3 Cord multiple flash (cumulative) mode These measurements are used when the light generated by the flash is inadequate for proper exposure. The repeated flash pops can be accumulated until the desired aperture is displayed. The cumulative number is infinite. Only one digit is displayed if the cumulative number is ten or more. Display returns 0 (0=10, 1=11, 2=12, etc.) 1. Hold down the Mode set button !0 and turn the Jog wheel t to select cord multiple flash (cumulative) mode . MODE 2.
5. Measurement CAUTION: • There is danger of electric shock if the meter is handled with wet hands, during rain, in areas splashed by water or where there is a lot of moisture. Under such conditions, it is recommended that you use the meter in the cordless flash mode, or wireless flash radio triggering mode and keep the Synchro terminal cap in place. NOTE: • The flash unit may flash when you connect the synchro cord or operate the POWER switch.
5. Measurement 2. When the light from the flash is received, the measured value (f stop) is displayed. Each time this is repeated, the accumulated value for the aperture and the number of cumulative flashes is displayed. Perecentage of flash in total exposure 1/10 f stop Number of cumulative flashes Set shutter speed 1st. time 2nd. time Measured f stop (total exposure) 3rd. time 3. The ready to measure mode will be displayed for approximately 90 seconds.
6. Advanced Functions 1. Memory function This meter can store up to nine measured values in memory for incident light and reflected light independently. This feature can be used in the following modes; Ambient light : shutter speed priority, aperture priority (L-558 only) or EV mode.
