Start to test- How to use Serge Tester IWT-5000A

Before seeIing how IWT-5000A works, let's just know its evolution history quickly.
The first modal of our surge tester is IWT-5000, not IWT-5000A . In fact, IWT-5000A is the fourth edition. That's because we always looks for a better product and better service.

We enlarge the storage from 100 to 360 sets waveform, add I/O communication, improve the inductance range from 20uH to 0.2 uH, and add the self-calibration function...etc.

Anyway, let's start to see how this machine work:

Basically you just have to save the waveform of golden sample in IWT-5000A and connect the other samples you want to test to the black and red high voltage test line.

Then press the test button , the pass or fail result will show on the LCD monitor. It is easy for operator to judge . (Unless he or she doesn't understand the meaning of PASS and FAIL.) The default comparison is 10 %, but it can be set by the operators.(Some customers set it up to 20% or less.)

For testing motor, apparently surge tester is using in the factory, but how to use it for the mass production? 

So if the operator has to to test 4000 pcs of  the samples in a  factory per day, how could IWT-5000A meet their requirement?

If the operator has to connect the samples to the high voltage lines and press the button to test it, then remove it and test another samples, the total testing time will be more than 10 seconds for 1 sample. If the factory only work 8 hours per day, it can not meet their requirement. 

The only solution is to design the Automated  system or the semi automated system to reach this numbers of the production.

It is a tough question to solve, since we are in Taiwan and most of our customers are from overseas. But our distributors are very reliable and know how to solve these problems.

This is a video shows how they design the fixture and a system to test the samples. (They test 4000/pcs samples per day successfully. )

Most of our end users use our handler I/O control mode for connecting external controller as automatic use.

Of course, they can also connect it to computer and write more commends for remote control.

Below is a video of how they test rotor with an old unknown tester.

You can see the operator has to look at the messy waveform on the monitor and judge whether it is good or not.

It is not friendly, without the pass and fail on the monitor, the end user has to be a very very experienced worker to judge the waveform is good or not , I suppose. 

So the best solution is to design a test system with our IWT-5000A, and this is also one of a project we are planing to work on in the future.

We call this modal IWT-5000A-12, why is we call it "12 " is because there are 12 sets of high voltage test lines for testing the 24 windings of the rotors. We will design a box for connecting the high voltage test lines and a customized fixture for testing the motor. 

(I will share more information here once the project is working on, because I want all information and detail are 100% correct here. )

Besides, in the future, we will design more model for our surge testers for the different application.

This is Leap, we are always willing to accept challenge . We welcome all customized cases so that we can leap.
