The detector uses sound and light alarm, automatic reversing or stopping at the same time. It is very convenient and reliable to operate and use.

Ⅱ. Performance Specification

1. Easy to operate and use.
2. It has high detecting accuracy, excellent anti-interference performance and excellent stability.

Ⅲ. Operation
1. When the machine is on the power supply, the main power switch is turned on, the power switch is on and the machine is in working condition.
2. It has ten levels of detecting accuracy and can be adjustable. Adjusting the detecting accuracy button according to your needs.

Ⅳ. Installation and Operation Procedures

1. Installation
①. The instrument is precise, so it is not suitable to work in high temperature and humid environment.
②. Pay attention to the surrounding environment, it is not suitable for having ferromagnetic objects. Such as electric fans, sewing machines and so on. Although it has anti-interference circuits, the ferromagnetic objects should still be avoided. 
③. The machine should be fixed tightly when working, because the shaking or vibration of the instrument may cause false alarm to the instrument.
④. People who operate this machine can not carry anything with ferromagnetic material on them. Such as keys, cell phones, steel rings, calipers, screwdrivers, etc.
2. Operation Procedures
①. Checking if there are sundries, tools on the inspection area.
②. Before each detecting, the sensitivity must be checked once to verify that the machine is normal. Then, it can be used. 
③. When detecting, the inspected items are placed in the detection area for detecting. If there exist broken needles, iron filings, the machine will alarm and the detection lamp will light.
④. Restarting the machine should be light after the operator checks the items that cause the machine alarm. Avoiding strong vibration to make the machine produce false alarm.
⑤. Inspection items should not be too thick, it should be within the specified scope so that the machine can achieve the effective detection of customer requirements. 
⑥. If the machine occurs abnormal sound, it should be stopped at once and checked. Restarting after removal of fault. 
⑦. The probe should be very stable and no items are allowed to be placed on the probe. It is not allowed to use the probe as a resting support.
⑧. The machine is affected by vibration or power supply fluctuation, and an alarm phenomenon happens occasionally. It is a normal phenomenon, not a fault.
⑨. Please pull off the power plug after finishing detecting.
