*The number of pulses
per rotation (0.5 to 200.0 P/R) is freely
selectable. |
Measurement accuracy |
Displayed value* x (±0.02%)
±1 count
* The displayed value is the count value excluding
figures after the decimal point.
The measurement accuracy of the line speed depends on
the rotational (r/min) accuracy. |
Peak hold function |
Maximum value (MAX), minimum
value (MIN) |
Memory function |
20 data (MAX) |
Over-range function |
The over-range alarm (ERROR
mark) is displayed when the measured value exceeds the
display range. |
Rotation upper limit alarm function |
The upper limit alarm ( ↑
mark) is displayed when the number of rotations exceeds the
preset upper limit value. |
Line speed calculation function |
Calculates the line speed
from the preset diameter value (mm) and the measured
number of rotations |
Accumulating function |
Provides a cumulative count
of the input signal pulses |
Cycle measurement function |
Measures the input pulse cycle
(however, when the cycle is less than 1 s, measures the
mean value of the input pulses) |
Trigger level adjustment
function |
A rotary dial at the
right-hand side of the device is used to adjust the
trigger level. |
