Caution
0v
(Overload) shall be checked and
adjusted
with
the acceleration mode (ACC) and
at the display of mode of
Peak.
Even if
0v
(Overload) is not indicated at the
velocity (VEL) mode or displacement (DISP) mode, there can be cases where the value
exceeds the measurement range.
To adjust the range at velocity (VEL) mode, when the acceleration (ACC) is at 20 m/s
2
range,
set velocity (VEL) to 20 mm/s range, and when the acceleration (ACC) is at 200 m/s
2
range,
set velocity (VEL) to 200 mm/s.
To adjust the range at displacement (DISP) mode, when the acceleration (ACC) is at 20 m/s
2
range, set displacement (DISP) to 200μm range, and when the acceleration (ACC) is at 200
m/s
2
range, set displacement (DISP) to 2000μm.
