content: I got a chance to see a set of test leads from IET Labs and thought I would pass the info along. I know there are a lot of opinions on what should be in a kit depending on what type of work you do but I think this kit has fairly wide coverage. The only thing missing are smaller grabbers for electronic work. List price is $94.00 but IET labs will sell them for $75.00 to anyone mentioning the EEV blog. IET webpagehttp://www.ietlabs.com/gr874-connectors/testing-lead-set-html.htmlComes in a nice woven nylon (not vinyl) roll up with handle and Velcro closure5 internal pocketsLeads have quality molding and are very flexible but they are not silicone. They are not marked for voltage rating so I asked IET if they had checked them. They had not but they checked them for the EEV blog audience.Quote from IET:"On the TLK-100 Test Leads the alligators, gripper are labeled 1000VDC. We have tested the cables to 1000VDC. Cables were wrapped in aluminum foil and potential applied between foil and center conductor of cable. Measurements were performed with 1865 Plus and measured resistances at 1000V exceeded 10Gohms."Main probes have 4mm banana jack noses and have snap on guides to prevent shorting adjacent pins. I think the probe tips are intentionally not sharp as they have a very small machined radius on the tip and they are made of plated brass.1000V CAT III and CE rating on the main probes.Flexible needle probes rated 30V. Sharp solid steel needle that can be resharpened. There is a spring section under the silicone tubing.Aligator clamps rated 1000VRigid sharp solid steel probes with protector caps rated 1000VLarge flexible nose grippers rated 1000V Grippers are piano wire and need some deburring.Fork terminals rated 30VAdapters for non shrouded jacks rated 30V

content: They do look nice, but as a practical matter I find these two sets more useful and versatile on an electronics test bench:RadioShack Test Lead KitRadioShack Micro Scale Test Lead KitI recommend them actually, in spite of the brand name. The big test lead set is 1000 V 90 deg C CAT III rated with nice bendy test leads and fairly pointy probes. Good value for the money.

content: I believe it's not silicone intentionally. Remember the keithley low voltage measurement book? Silicone has some serious Seebeck junction coefficients

content: That looks like the "China Export", not real CE mark. The C and E are too close together.If they tested it and it meets the requirements then I have no problem, but just letting you know it might not be really "CE certified".

content: Quote from: amyk on September 05, 2012, 08:34:03 amForget about the CE mark. Real or "China Export" doesn't matter. The real CE is a self-certification, not verified independently. A crock has no qualms to put a real CE sign on a substandard product. If you want to get an idea (tip of the iceberg) of what crap gets sold in the EU with real CE signs, have a look athttp://ec.europa.eu/consumers/dyna/rapex/rapex_archives_en.cfm
