8‑4. Installing position of the probe cable and the main body
Vibration and swinging of the probe cable
⑭
cause malfunction.
The position of the probe and the main body is ideal that they are installed as close as
possible to protect them from invasion of the noise from the probe cable
⑭
.
Note: Even if in this case, keep a distance more than 1m at least.
●
When the main body is desired to be installed away from the probe:
・
Firmly fix the probe cable
⑭
not to swing.
・
Do not band the probe cable
⑭
parallel to cables or cords etc. generating noise.
And avoid to pass through around switch boxes generating sparks.
・
The probe cable can be extended up to about 15m. In this case, pass the cable through
pipes firmly fixed.
・
When the facility is newly designed, use brushless motors for driving motors of lines.
8‑5. Accessories and sub‑materials
When metallic accessories and sub-materials e.g. buttons, fasteners are fitted in an object
to be inspected, the Detector occasionally detect them as well as iron pieces and needles.
・
Specify to use the buttons, fasteners and other parts indicated as "Detection support type"
at the design and planning stage for the accessories, sub-materials e.g. metallic buttons,
fasteners, etc.
8‑6. Adjusting the sensitivity
The Detector is in the highest sensitive condition at the pointing position [10] of the sensitivity
adjusting dial.
When using the Detector lowering its sensitivity to avoid effects of accessories, sub-materials
and surrounding noises, start the detecting (needle detection) work after confirming that the
Detector can detect the iron pieces and needles required to detect under lowered condition of
sensitivity.
■
Noises which generate by the various causes mentioned above are added up and invade into
the circuit and cause malfunction.
Remove these factors as possible to use the Detector in its highest sensitive condition.
