Is it necessary to calibrate the fluke dtx-1800 test accuracy?

Time to dial 1994 year , Fluke DSP Series copper cable tester was born , To 2004 Next year , synchronous DTX-1800 Series launch , Until then 2015 year DTX-1800 The series is fully offline .DSP The reigning time is 10 year , and DTX-1800 In office 11 years , And to arrive 2018 year 6 month 30 The official warranty of fluke was suspended on August th . From the above time points ,DTX-1800 series , It is just at a special stage of China's rapid economic development , At the same time, all kinds of testing requirements are gradually rigorous in a special period . Its stock on the market is very objective , Since fluke officials do not support maintenance 、 maintain 、 calibration , How to dispose of these stock equipment in the market ？

Slightly wire the weak current , That is, we usually say that friends who know about network cabling know , At present, most twisted pair cables used in the market are between CAT5E(100mHz)-CAT6A（500mHz）, It is also the main part of the finished product shipment of cable manufacturers .

​DTX-1800 The test bandwidth can reach 900mHz, In other words, it can fully meet the current market demand . Support TIA,ISO,GB50312 And customized by the manufacturer . You can test the length of the cable 、 Line sequence diagram 、 Insertion loss （ attenuation ）、 Return loss 、 Near end crosstalk , All test parameters specified in the standard .

DTX-1800 It is indeed a classic twisted pair test instrument , First of all , Fall resistant ; second , Standby time factory ; Third , Stable , Low failure rate ; front 2 Points can be realized in the process of use , Let's take the third point , Take it out alone .

The hour hand points 2022 year 7 month 28 Japan , To present position DTX-1800, list 17 years , It's also possible to stop supporting from the original factory 9 year . In these long years , Everything happens . from DTX-1800 Vulnerable parts begin to talk .

1,DTX-CHA002 Interface of channel adapter - The first loss piece , Once the official suggestion 5000-1000 After 10000 tests, it has to be replaced . The reason is often plugging , Lead to pin Poor contact due to deformation of the needle , In addition, the exposure time is too long , Oxidation leads to .

2, Battery aging .

3, Screen failure , Like a flower screen , No display , Partial Aging leads to .

4, Accidental fall injury , As a result, the machine cannot be started normally .

5, Enter liquid , Cause the machine to burn .

Probably the above are the common hardware failures to be handled , But the most important point is accuracy recovery , That is, original factory calibration . Fluke FLUKE It is recommended to calibrate once a year , Ensure the test accuracy of the instrument .

Repair and calibration , Since fluke doesn't support it , How to repair and calibrate the fault ？

If you have the above situation, you can confide in me , I will definitely give you a satisfactory answer .
