Operation
■ 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 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.
