Let's take a quick look at the 4200 Series.

It was designed to test for continuity, isolation, opens, and miswires.

It can also analyze components, such as resistors, capacitors, and diodes, and perform 4-wire resistance measurements.

It's compact, lightweight, and self-contained, for easy mobility around the production floor.

The testers come standard with 128 test points, but are expandable up to 1,024 test points using 128 test point expansion boxes.

While both testers are fast and versatile, the 4250 can high-pot up to 1,500 volts DC.

It's also available in 2,000 volts DC or 1,000 volts AC.

Since both testers have the same base features, we'll be focusing today's video on the 4250.

On the back of your tester, you'll find inputs for digital I.O., serial, your probe, USB to PC, USB for peripherals, such as a barcode scanner, an Ethernet port, Wi-Fi, and power.

To power on your tester, simply plug in the power supply into the back of the tester and press the button to power on.

In order to attach your device to the tester, the 4250 utilizes the Cirrus adapter system.

Simply take the adapters that fit your cable and position them onto the front of the tester.

For this demonstration, we'll be testing a batch of simple cables.

The 4250 is powered by the easy-to-use Cirrus OS, which has a wide variety of features, including multiple languages.

You can also share test programs and printers across multiple units on the same network.

So let's go ahead and create our first test.

The easiest way to create a test is to have the 4250 learn a known good cable.

Notice how quickly the tester learns the cable and then displays a list of connections for you to review.

If the connections all look correct, go ahead and click Save As.

Then select New.

Here, you can name your test program.

For this demonstration, we'll go ahead and just call it Test.

Now, go ahead and select your test.

You can do that by pressing the Load button and selecting your test.

Your program should now show as the loaded test at the top of the screen.

You're now ready to begin testing.

Remove your known good cable from the tester.

Grab your first cable from the batch and attach it to the front.

With the cable attached, go ahead and select Test.

The tester will run a low-voltage test.

For this demonstration, we've also included an intermittence test, at which point you can manipulate the cable and help expose any faults in the wire.

As no errors have been found, the cable has passed.

Go ahead and disconnect your cable from the front.

Place it in your good batch, and you're ready to test your next cable.

To demonstrate the high-voltage capabilities of the 4250, we've attached a demo cable with more components.

We've already created a test for this cable using the tester's Learn function.

However, if you have to edit your test after it's been created, select the Edit button.

Here, we can select High Voltage and turn the High Voltage test on.

Perhaps there are also certain specifications you need to change, like your connection resistance.

Simply select Low Voltage, and then Connection Resistance.

For this test, we'll go ahead and put in 10 ohms.

Once finished, hit OK, and then select Save.

Finally, hit Continue.

We're now ready to test our cable with components.

Like before, it will quickly run through the Low Voltage test, at which point the tester will prompt you to start the High Voltage test.

Simply select Start Test.

Once the High Voltage test has been cleared, you'll see the Passed on the screen.

However, let's go ahead and introduce an open error.

Go ahead and click Retest.

The tester, upon identifying the failure, will display Failure, as well as additional details.

Such as the test that failed, which component was missing, and where the missing connection is.

In this case, J4-01 and J1-08.

If the operator can identify the error and correct it, they can simply click Retest to run it again.

As the error has been corrected, the cable will now show as Passed.

This has been a demonstration of the 4200 Series Benchtop Tester from Cirrus.
