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.
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.
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.
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.
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.
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.
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!
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.
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.
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.
