Common faults and processing plans used by RoHS tester:
As a high -precision instrument, the RoHS tester, there are still many places to pay attention to the usual use and operation. For the various problems encountered in the use of daily instruments, there are no questions from professionals. The fog, as a editor who has been struggling for several years in the industry, today I organized the most related problems and solutions encountered in the use of the RoHS tester in the use of the RoHS tester. I hope to help your daily instruments use operations.

In recent years, with the continuous improvement of people’s awareness of environmental protection, the problem of environmental pollution caused by electronics and electrical products has been increasingly valued. RoHS is a compulsory standard formulated by the EU legislation. It is mainly used to regulate the material and process standards for electronic and electrical products. The item, and the content of the lead cannot exceed 0.1%.

The RoHS tester is an equivalent high -voltage liquid chromatography system, which is composed of manual inlet, high -pressure constant current pump, color spectrum column (optional column thermal box), UV ultraviolet detector four units, and powerful chromatography software. All unit modules have high -efficiency liquid phase compatibility, allowing all users to obtain better performance, more economical equipment and minimum consumable expenses.

Common problems encountered during the use of RoHS tester
1. The influence of cadmium, lead, and mercury measurement results will be affected under what circumstances, and where can I see from? What should I see?
Answer: Generally speaking, cadmium and bromine Ka peaks are disturbed; lead is disturbed by BI, AS, BR, and Fehefeng; mercury is interfered by W, which can be seen from the spectrum.

2. Can the product be measured accurately when there is an electroplating layer?
Answer: No. Test it with a coating once and test it again.

3. If there is a hardware in plastic products and cannot cut the product, how to measure RoHS, is it the analysis group of the plastic analysis group or the hardware of the hardware? It is the test result of the measurement of plastic or hardware?
Answer: These samples should be tested in two parts. The coating is used to use a metal curve to remove the plating curve.

4. Measurement is poor, how can I minimize the difference?
Answer: The sample should be flat, with a certain thickness, a single material.

5. When testing the sample, if you do n’t know the material information of the material in advance, how should I choose the analysis group?
Such as: what analysis group testing for tin paste, stainless steel, etc.? Can this instrument test liquid matter?
Answer: You can use EASY qualitative test first, and then select the method test; test liquid, but the test is safe, not omitted.

6. Will the metal materials contain br and CL? (BR and CL are flame retardants). If it does not contain, why does it contain BR in the result of the precision test of the iron alloy when testing the U iron?
Answer: Metals do not contain br and cl and clmnown; this is caused by BR due to iron interference.

7. Why does the RoHS tester bring different test sample spectra?
Answer: ① Choosing a sample measurement type is different.
② The sample spectrum accidentally covers a sample test.

8. In the test, why is it prompting that the sample is too small?
Answer: This problem occurs. In the analysis software, there is no such phenomenon in the RoHS software. It is when the “control counting rate” is selected in the “device parameter” option. The following reasons are measured because the following reasons:
(1) The wrong curve
(2) The sample is not very good or too small
(3) Wrong information

9. Why do you measure lead, tin, lead summit drift?
Answer: It is not drifting, it is the illusion of the spectrum observed, because it is doped by the tin, causing the nearby peak.

10. Why are there only dozens of hundreds of tested measurement counts to limit the test counting of harmful substances (RoHS)?
Answer: There may be debris blocking sensors or accurate. In addition, the optical system failure or instrument setting parameters of the instrument.

11. What RoHS tester, after replacing the direct device, the software freezes and turn off and restart and use it?
Answer: This phenomenon is rare, and the computer operating system is most likely to affect the crash of testing software.

12. Why is the data loss after the RoHS tester is completed?
Answer: (1) is an incorrect preservation path
(2) Nonally shut down
(3) Special circumstances in use

13. Why is the storage path corresponding to the spectrum and the installation path of the software?
Answer: Software design requirements.

14. Why do you sometimes choose the counting rate of automatic adjustment, sometimes there is no choice?
Answer: It is accompanied by test samples and measurement methods. The principle is that when the result is not related to the sample counting rate, you can adjust the counting.

15. Why does the RoHS tester need to preheat for 5 minutes?
Answer: The instrument fully preheating can ensure the accuracy of the test data. We recommend that you warm up for 30 minutes. And fast warm -up method.

16. Under the same conditions, the deviation of the results of the two consecutive times is large? In fact, what results do we choose?
Answer: Under the same conditions of large deviations, there are four reasons:
① The imbalance caused.
② Comparison of data from the device.
③ The instrument is not disturbed by the outside world, such as the test result of the sample equipment: power interference.
④ The hardware failure of the instrument is in the non -hardware failure, as long as the RoHS tester is proved.

In the use of the RoHS tester, you need to pay attention to the following operations:
1. The instrument will generate ionizing radiation. Make sure the instrument should not be tested in the air during testing; do not test the instrument on the air; do not hold the sample for testing;
2. The RoHS tester is operating, do not open the protective cap of the instrument or not align the test instrument to the human body;
3. Each time you open the instrument and work for 4 hours in a row, you must check the instrument;
4. It is strictly forbidden to operate the instrument without special specified personnel. When operating, it must be performed according to the operation steps. Any wrong operation will cause the test results and service life of the instrument.
5. After the test is completed, click the “Settings” X -ray pipe button. In the dialog box that appears, click the “Open the High -Voltage Power” button, and then click OK. When the tube flows will be OK, you can perform the next step. Click the operation to operate. The “closed button” in the upper right corner of the interface is closed after the software is closed.
