■ Basic Setting
Setting of Selectors
The selectors can be turned clockwise and counterclockwise to
select the desired time unit, time range, 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
• H3CR-A Multifunctional Timer
The operation mode A to E, G, and J of the H3CR-A can be selected.
Use a Phillips head or flathead screwdriver to turn the selector
switch. The operation mode can be set to one of eight modes. The
window on the top shows E, G, J, A, B, B2, C, or D to indicate the
selected mode. On the H3CR-A8, the window on the top shows E, J,
B, A, or B2.

The desired time unit (sec, ✕10 s, min, ✕10 m, hrs, or ✕10 h) is

time unit selector located at the lower right corner of the front panel.
A time range (1.2, 3, 12, or 30 for H3CR-A@/2.4, 6, 24, or 60 for
H3CR-A@-301) is selected with the time range selector at the lower
left corner of the front panel, and the selected time range appears (in
the window at the lower right part) within the plastic frame of the time
setting knob.

shows 1.2, 3, 12, or 30 to indicate the scale number selected with the
