Radiation Meter Radiation Test for anti radiation stick demo CG-1 SFC


This is a modern design, stable performance, all-aluminum enclosure, low cost multi-purpose mobile phone radiation tester. It can be used to test CDMA network and GSM network mobile phone radiation. Integrated processor with four instruments to measure the maximum value can be displayed 9999, 5 times more than general meter that only display max 1999. So this instrument can measure the value of very low radiation CDMA network segment 133 cell phone radiation. Although it is not professional radiation meter but the cheaper practical demo equipment.

Test Theory

The tester can detect the area with 800-2000MHz frequency electromagnetic signals in a special sensor. When the test area receives electromagnetic signals within frequency, the strong voltage value of electromagnetic signals can display on the instrument LCD display, the display unit is volts/ meter. However, in order to facilitate reading the data observed, the user can see only the maximum value up to 9999. If it is more, this value is displayed as EEEE. Instrument design uses aluminum metal shield external to interference signals, so that it gets more accurate. LCD screen has blue LED backlight, display values can see clearly in any light.
The tester can use GSM networks and CDMA networks for mobile phone radiation in simple test experiments. It is simple and easy to master, test results is stable. This instrument is ideal for mobile phone radiation shielding .

Instruments Use Note: As the tested phone models, using the network, testing environment and test different methods are different, the oberved results will differ. At the same time, we have to understand that this instrument is not a professional measuring instruments, can only be used for simple observation of mobile phone radiation (electromagnetic field strength) change of use.

 

Use Method

1. The new equipment is generally not with the battery. Use a small Phillips screwdriver to open the back cover equipment, fitted with 3pcs AA batteries before use.
2. Press the device power button, when the liquid crystal display 000 it can be used. Press it again to Close. Due to electromagnetic interference test environment, Instruments may fluctuate around + -000, this is normal, it won't affect the test.
3. Place the mobile phone near to the test area (within 0-2 cm) , then use another mobile phone to call it or use it to call. Don't answer the phone(radiation value will decline much after answer, result is difficult to observe). Display value on test always change in the time (not a fixed value). Observe the highest values, to get a rude idea to analysis. When doing comparative experiments, it is also observed before and after the two rounds of testing each device shows the maximum value for comparison.

 

4. The instrument used for measuring the shielding effectiveness of cell phone radiation patches comparative experiments should follow the steps below.

 (1) Using the part of mobile phone antenna to near the test area to get the highest value.
(2) Put radiation stick well within the area, then let the phone near the device test area, then make or receive calls (Never answer the phone, the bigging few seconds of radiation are relatively high). So, only observe the value within a few seconds, make a few more observations and recorded the highest value at this time.
(3)Compared with the two highest value to get an idea about cell phone radiation stick.

The below is wrong operation:

- The display value is different even in the same environment from wireless signal strength of emission or reception of different brands of mobile phone. And the distance between the test area and the phone will also directly affect the test data.

- Different antenna location for different brands of mobile phone, please use the equipment carefully to find where is the antenna of phone. The higher display values are, the nearest mobile antenna is. Then paste the radiation patch to compare test.

- This test is only observed on radiation shielding effectiveness, another function of our stickers can resolve radiation wave targets the human brain cannot be observed.

-In order to offer better demo, it must to stick on the place of antenna radiation sources to demo Shielding Effectiveness. However, in actual use, because some mobile phone antenna is mounted on the camera around, can not be affixed directly. Then just simply paste the patch on the phone back . If what you ordered is dual function of patch, both anti radiation and battery saver/extender, you can also stick on batteries. If you don't stick where the antenna is, the demo of shielding effectiveness maybe be poorly observed.

For how to demo, you can reference to our demo tester video, this is recorded in Lab.

-This tester only for GSM phones. If for CDMA mobile phone, you need put the phone’s antenna and tester area very close and see carefully just callings in/out, the display value is very low and disappear soon. This prove radiation is less for CDMA phones.

-As the meter is very sensitive, after open the cover, you need seal it well to avoid radiation go in. When test, as you have not stick over well on the test area, you can do like so, putting 4pcs to full cover the test area and block radiation go in to demo better. In the same time, stick the radiation stick on mobile phone too.

Important Notice: again pls! All test result depend on many complex condition factors, you need get your best experience on test if you find it is not good demo. Do it many times you will get good idea. Remember, this is not professional test, only related value, only for demo. We have test reports from professional Lab to prove it actually perfect work.
