Tester Trouble Shooting

I'm getting an Interlock Open failure. What does Interlock Open mean?

All SCI testers have a remote interlock feature designed to provide you with added safety. This feature utilizes a set of contacts that must be closed in order for the tester to enable output voltage. To enable High Voltage output, ensure your Signal Input Connector is plugged in to the rear panel of the tester. If you're using interlocked DUT Enclosures and the tester displays the “Interlock is Open” error either your test enclosure is open or the Interlock disable connector is not properly connected.
I'm getting a Hi-Limit failure. What does Hi-Limit mean?

A Hi-Limit failure means Leakage Current is greater than or equal to the programmed high limit parameter. If your DUT is getting a Hi-Limit failure it could mean the insulation of that individual Device Under Test (DUT) is weaker than it should be. If multiple DUT's are receiving Hi-Limit failures in a row this could mean that your product's insulation is relatively weak. For quality purposes, you should re-test the Hi-Limit of failed DUT's and consider possible defects in insulation.
I'm getting a Lo-Limit failure. What does Lo-Limit mean?

A LO-Limit failure means one or more of your test leads may not be properly connected. Verify proper test lead connections; both to your tester and to your Device Under Test (DUT).
If your test leads are properly connected, a LO-Limit failure could also mean you have a bad test lead or test cable.


What is an RMA?

An RMA is a Return Merchandise Authorization. We use the RMA process to provide you with the best service and support. After filling out our RMA form, you will receive a custom RMA number which will help us both identify your tester.
How do I request an RMA?

You can submit an RMA by giving us a call (1-847-932-3662) and having us set it up for you, or by filling out our RMA form yourself. We'll get back to you within 24 business hours with your custom RMA number. After you receive your RMA number, you may send your tester in to us. Make sure you label your shipping box with your RMA number so we can identify your tester when it arrives at our calibration lab.
What methods of payment can I use to pay for my service order?

• Credit Card: Add a credit card number to pay for your service order. **Please note: We will not charge your credit card until we have serviced your tester.

• Purchase Order: To include a purchase order, you must first have terms established with Ikonix. To apply for terms with us, follow this link.

Test Settings & Features

What should my test settings be?

To determine your exact test settings, ideally you should reference your test standard. You may also utilize our Guide to Electrical Safety Testing document on page 11. If you need additional assistance on setting your test parameters, feel free to reach out!
What should my leakage current limits be set to?

Leakage current limits vary per standard and per product type and are strictly defined within your Standard. Please begin by checking the Leakage Current Limit table within your standard. You may also reference our Safety Reference Chart on page 22, within our Guide to Electrical Safety Testing.
Where should I set my voltage?

To determine your exact test voltages, ideally you should reference your test standard. You may also reference our Guide to Electrical Safety Testing document beginning on page 10, to learn more about the different test types. If you need additional assistance on setting your test parameters, feel free to reach out!
Why would I need a RAMP Timer?

A RAMP Timer is recommended for DC High Voltage Tests (such as DCW Hipot or Insulation Resistance Tests). RAMP Time allows for a smooth rise of voltage from zero to the Voltage set point.
What does the Connect feature do on the 290 Series?

The SCI Connect feature joins together independent test steps, allowing you to perform a more demanding test sequence on your Device Under Test (DUT).

Electrical Safety Testing

What is a Hipot Test? / What is a Dielectric Withstand Test?

A Hipot Test or Dielectric Withstand Test is used to stress the insulation of a product far beyond what it would encounter during normal operation. High voltage is applied from the mains-input lines to the chassis of the product in order to look for insulation breakdown. The Hipot Test can be performed using either an AC or a DC voltage.
What is a Ground Continuity Test?

The Ground Continuity test is used to determine if the safety ground circuit of a product is continuous and intact. A low voltage is applied from the chassis of the product to the ground pin to determine if the ground circuit is continuous.
What is a Ground Bond Test?

The Ground Bond test is used to verify that the ground conductor of a product has a low enough impedance to handle any fault current to ground. High current flows from the ground pin of the product's line cord and through the chassis in order to determine if the cabling is capable of handling excessive current flow should a fault occur.
What is an Insulation Resistance Test?

An Insulation Resistance test is used to verify the resistance of a product’s insulation by applying a DC voltage and measuring the resulting leakage current.
