Test Procedure with IEC 62368-1 Annex D.1 Impulse Test Generator

Generator Setup

Start by placing the KP-1950S on a flat, stable surface. Make sure the area is clean and free from clutter. Plug the power cord into a grounded outlet. Turn on the main power switch. The touchscreen will light up and show the home screen. Check that the emergency stop button is not pressed. If it is, twist it to release.

Tip: Always keep the operator manual nearby for quick reference.

Check the calibration certificate before you continue. This step confirms that your IEC 62368-1 Annex D.1 Impulse test generator gives accurate results. If you see any error messages on the screen, stop and contact technical support.

Connecting the Device Under Test

Now, prepare your device under test (DUT). Place it on an insulation mat to prevent accidental shocks. Use the test leads to connect the output terminals of the KP-1950S to the input points of your DUT. Make sure the connections are tight and secure. Attach the grounding cable from the generator to the DUT’s ground point.

• Double-check all wires for damage.

• Make sure no metal parts are exposed.

• Keep your hands away from the test area when the generator is on.

Note: Good connections help you get reliable test results.

Configuring Test Parameters

You will now set the test parameters on the touchscreen. The KP-1950S makes this process easy. Follow these steps:

1. Tap the “Settings” icon on the screen.

2. Choose the waveform you need. Select either 10/700μs or 1.2/50μs, depending on your test standard.

3. Set the output voltage. Use the up and down arrows to adjust the value. The IEC 62368-1 Annex D.1 Impulse test generator lets you choose from 0.01 kV up to 6 kV.

4. Pick the polarity. You can select positive, negative, or both. Some tests require you to test both polarities.

5. Enter the number of pulses. You can set this from 1 to 999.

6. Set the interval between pulses. Use the time setting to control how quickly each pulse fires.

Here is a quick reference table for parameter settings:

Parameter	Typical Setting	How to Adjust
Waveform	10/700μs or 1.2/50μs	Select from menu
Voltage	0.01 kV – 6 kV	Use arrows or keypad
Polarity	Positive/Negative/Both	Tap to select
Pulse Count	1 – 999	Enter number

By following these steps, you can use the IEC 62368-1 Annex D.1 Impulse test generator to perform accurate and safe compliance testing. This process helps you meet international safety standards and protects your products from electrical surges.

Results and Compliance

Reading Test Results

After you finish the test, you will see the results on the touchscreen display. The KP-1950S shows important data like the number of pulses, voltage levels, and waveform type. You should check if the device under test (DUT) worked as expected during the impulses. Look for any signs of damage, sparks, or loss of function. If your DUT keeps working and shows no visible problems, you can move to the next step.

Tip: Always compare the displayed results with your test plan. This helps you spot any issues quickly.

Pass/Fail Criteria

You need to know what counts as a pass or fail. IEC 62368-1 Annex D.1 gives clear rules. Your DUT passes if it does not break down, lose insulation, or show unsafe behavior during and after the test. You should check for:

• No electrical breakdown or arcing

• No loss of insulation

• No fire, smoke, or sparks

• DUT still works as designed

If you see any of these problems, your DUT fails the test. You must fix the issue and test again.

Criteria	Pass Condition	Fail Condition
Insulation	No breakdown	Breakdown/arcing
Functionality	Works as designed	Stops working
Safety	No fire or smoke	Fire, smoke, sparks

Documentation for Compliance

You must keep good records for certification. Write down all test settings, results, and observations. Include the date, operator name, DUT details, and calibration certificate number. Attach photos if possible. This documentation proves you followed the standard and used the IEC 62368-1 Annex D.1 Impulse test generator correctly.

Note: Good records help you pass audits and get your product certified faster.

Keep your documents safe and organized. You may need to show them to certification bodies or customers. Accurate records support your compliance and help your business grow.

Troubleshooting and Best Practices

Common Mistakes

You may face some common mistakes when using the IEC 62368-1 Annex D.1 Impulse test generator. Knowing these errors helps you avoid them and keeps your testing process smooth.
