使用說明 ： 1 : Connect the 9 volts network adapter in the plug at the back of the device. 2 : To put on the device: switch on the right. Leds flashes approximately 3 seconds. As soon as the green led is lit, the device is ready for a measure. While leds are flashing, an automatic calibration is made. The calibration is made before every new measure and insures the adaptation of the sensors to the magnetic environment of the workplace. 3 : Put or pass the object to be measured on the target. The number of lit leds corresponds to the magnetic state of the object. As long as you move the object on the target, the sensors measures and memorize the highest detected value. The display is consequently corrected. 4 : While leds are flashing, no object must be put on the target. 5 : If after a measure the leds does not flash it means that the last variation of measure is too low to be registered. It is enough to switch off and then relight the device by activating the on/off button.
