CAUTIONS IN OPERATION
● Before using the Detector, read this INSTRUCTION MANUAL thoroughly for correct and
safety use.
● Keep this INSTRUCTION MANUAL carefully and refer to it when necessary.
● The Detector helps to simplify and to raise efficiency of detecting/inspecting work of
iron needles and broken needles straying in sewn garments.
● To remove straying needles, parallel uses with other various methods are recommended.
● The Detector is an iron piece detector for detecting iron pieces which stick to a
magnet. Nonferrous materials such as stainless steel, brass, aluminum and so on which
do not stick to a magnet can not be detected.
However, certain mass or size of material will react to the Detector occasionally.
● The probe emits strong magnet force.
Be sure to keep the following items away from the probe, otherwise these items may
become out of order occasionally.
Magnetic card such as cash card, credit card, commuter pass and so on. Floppy disc.
Precision instrument such as wristwatch and so on.
● Be sure to confirm the detecting ability before commencing the needle detecting work.
●
Detecting ability is influenced by the quality, size, speed, and direction of the
needles or iron pieces to be detected.
Confirm with the sample to be detected in the same height and speed as the actual
operating condition.
●
Generally, there are tendencies for detecting needles or iron pieces as follows;
【Quality】
Mild steel is easier to be detected.
Nearer to steel, harder to be detected.
【Size】
Larger in size, easier to be detected.
【Speed】
Generally, faster in speed, easier to be detected.
When the production line can not be increased speed, please contact us.
【Direction】 It depends on the shape of iron pieces.
Detecting ability of a long, slender object such as needles differs
from the direction, lengthwise or sideways.
● Be sure to use needles made of iron.
There are some marking pins, pins and so on made of stainless or brass which do not
stick to a magnet. These materials can not be detected.
● The using methods deviating from the efficiency and the function of the Meter and
remodeling are beyond the control of the manufacturer, so that the manufacturer can not
accept responsibility for any loss resulting from above mentioned uses and remodeling.
