Basic Operation
Setting of Selector
The selectors can be turned clockwise and counterclockwise to
select the desired time scale, or operating mode.
Each selector has a snap mechanism that secures the selector at a
given position. Set the selector at a position at which it is secured. Do
not set it midway between two securing positions or a malfunction
could result from improper setting.
Selection of Operating Mode (except
for H3DS-AL)
The H3DS-ML/-SL can be set to any one of the operating modes A to
J. Turn the operating mode selector with a screwdriver until the
desired operating mode appears in the operating mode display win-
dow.
H3DS-ML (8 modes): A, B, B2, C, D, E, G, J
(In order of appearance)
H3DS-SL (4 modes): A, E, B2, J, E, E, J, J
(In order of appearance)
Note:
Letters that appear more than once indicate exactly the same
operating mode.
Selection of Time Scale
The time scale is selected by turning the time scale selector. The
time scales will appear in the following order in the time scale display
window on the left of the selector:
1 s, 0.1 s, 1 h, 0.1 h, 10 h, 1 h, 1 m, 0.1 m.
Note:
The time scale “1h” appears twice. Both instances indicate ex-
actly the same time scale.

tor can be locked using the Y92S-38 Lock Key, a special pen type
