The transmitting antenna is connected to the transmitter. The power of the signal is generated by the transmitter. Figure 1 Layout of the test equipment
6.16.3.3 Adjust the frequency of the signal generated by 1MH2~10VMH$. The reading of the instrument is 15V/m. During the test, the frequency of the signal generated by 1MH2 is constant at a speed of not more than 0.0050ct/min. At the same time, the detector should be rotated to observe and record the working conditions of the detector. If the transmitting antenna used is directional, the transmitting antenna should be reversed first and aimed at the detector for testing. In the frequency range of 1MHz--! 000MHz, the test circuit is carried out with horizontal polarization and vertical polarization of the antenna respectively. 16.3.4 During the test, observe and record the working status of the detector. 16.3.5 The test tube should be carried out in a screen. In order to avoid large measurement errors, the position of the antenna should meet the requirements of Figure 2. 6.16.3.6 After the test, measure the action value of the detector by S.6.3 and S.6.4 Test equipment The test equipment should meet the requirements of Chapter 4 of R16R3%-1997. 2 Antenna location diagram
6.17 Electrostatic discharge test
6.17.1 Purpose
To test the suitability of the detector to electrostatic discharge caused by static electricity personnel and objects: 6.17.2 Requirements
The anti-static discharge performance of the detector shall meet the requirements of 5.1G. 617 3 Method
6.17.3.1 Place the inductor on the insulator bracket and connect it to the averaging board at a distance of not less than 1W\1. Turn on the power and let the detector dry for 11 seconds.Turn on the power and make the depth detector in the normal state for 2 minutes. 1i
