On the main screen, while pressing the
[MODE] button, press the W button five times.
[51.out] is displayed on the main display (upper
level).
While pressing
the [MODE]
button, press the
W
button five
times.

Use the S/T buttons to display the signal that
you want to output in the sub display (lower
level). The signal will be output when it is
displayed. Press the [MODE] button to
proceed to the next step.
[MODE] button

When you turn ON external input 1 to external
input 4, the corresponding part of the display
will change from [_] to [o].
From the right, the parts correspond to external
inputs 1, 2, 3, and 4.
Press the [MODE] button to proceed to the next step.
(Example) [___o] indicates that external input 1 is
on.
[o_o_] indicates that external inputs 2
and 4 are on.
[MODE] button

The upper limit, middle value, and lower limit
of the analog output are generated. This is not
displayed when the analog output is turned
OFF. Press the [MODE] button to proceed to
the next step.
(Example) When the analog output setting is 0 to 5 V
5 V is output for Hi, 2.5 V is output for Mid,
0 V is output for Lo, and 5.5 V is output for
Err.
