User manual SEKONIC TWINMATE L-208

[. . . ] In order not to crowd the controls, four functions which are less frequently used, are confined to DIP switches, located in the battery compartment. Because of its many features, the L-358 requires this rather extensive manual. But since you will never use them all at the same time, once you have learned all about it, it is simple and its use will become second nature. The Flash Master L-358 has undergone extensive quality controls at every step of manufacture. [. . . ] The measured value (f stop value) will be displayed. Set shutter speed Measured f stop value Percentage of flash in total exposure 1/10 f stop measured f stop value (total exposure) -15- ENGLISH 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 fire when you connect the Synchro cord or operate the POWER Switch. · For flash units with extremely low electric trigger voltage, the flash may not fire. In this case, make measurements in the cordless flash mode or wireless flash radio triggering mode. Reference: · It is possible to switch between full, 1/2 and 1/3 shutter speed stop by setting DIP switch 3 and 4. · 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 film speed 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. 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. Only one digit is displayed if the cumulative number is ten or more. Display returns 0 (0=10, 1=11, 2=12 etc. ) 1. Slide DIP switch 2 to MULTI (see page 8) to the ON position. Hold down the Mode set button !0 and turn the Jog wheel t to select cord multiple flash (cumu. Turn the Jog wheel t to set shutter speed. When setting shutter speed, first check the settings to confirm that they correspond to the settings available on the camera. Connect the Flash synchro cord to the meter's synchro terminal i. 4. Press the Measuring button !5 to trigger a flash. The measured f stop value at that time will be displayed. Each time this is repeated, the accumulated f stop value and the number of cumulative flashes is displayed.
