- This example shows quality control of the harness device included
in the sliding door mechanism by using the sound generated during winding
the harness. Drive a motor of wire harness system in a sound insulating box and
the LA-1410 Sound level meter measures the sound generated during winding
the harness. Then the CF-4700 performs frequency analysis of the AC output signal
from the Sound level meter to make OK/NG judgment of the partial overall level
in a specific frequency band.
- Judgment area block (max: 20 blocks) is set up by the specified
frequency range on the power spectrum and the upper/lower-limit levels.The most suitable judgment method can be selected from 6 kinds of judgment methods (level, peak level, peak max, insideMax, partial overall or area rate of content). The Digital I/O
function also enables control by PLC* via comparator output.
- The measurement results can be stored into a PC via LAN or RS-232C
interface.
