5. Measurement
WARNING:
•To avoid a danger of choking, please place Synchro terminal cap in a location where an infant cannot reach and accidentally swallow it.
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 electronic flash unit may trigger when you connect the Synchro cord or operate the Power button.
•Triggering voltage is 2.0 to 400 volts. Below 2.0V, trigger flash with the cordless flash mode (see page 22) or wireless flash radio triggering mode (see page 28), not with synchro cord.
•If you measure flashbulb, be sure to cheek the synchronized range and set the proper shutter speed.
Reference:
•It is possible to switch the shutter speed between full, 1/2 and 1/3 stops by custom setting (See page 40).
•The shutter speed can be set from 30 minutes to 1/1000 of a second. After 1/1000 sec, the meter can be set at the following intermediate speeds: 1/75, 1/80,1/90, 1/100, 1/200, or 1/400.
•If the ISO sensitivity is changed after the measurement is taken, the new converted measured value (f stop value) will be displayed.
•After measurement, the F stop value corresponding to the shutter speed is displayed when the shutter speed is changed with Jog Wheel.
•Readings outside the display range or beyond the measuring range are similar to the previous instruction (see page 16).
•You can select aperture scale or EV scale by holding Mode button and pressing AVE. /⊿ EV.
Measurements are made by the meter receiving the light from the flash. This measurement mode is used when the Synchro cord will not reach because of the distance between the flash and meter or when use of the Synchro cord is inconvenient.
1. Hold down the Mode button ⑩ and turn the Jog wheel ⑤ to set 
.
2. Turn the Jog wheel to set shutter speed. When setting shutter speed, first check the settings to confirm that they correspond to the settings available on the camera (camera flash synchronization).
