Larry Is it "floor standing" or "hand-held and floor resting" ?
* You don't say how large / heavy the unit is, but EN 61000-4-3 allows floor standing equipment to be raised onto a 0.8m high non-conductive platform - which puts it correctly into the field * When I've previously ESD tested similar types of detection equipment I had to perform the test with the EUT some distance from metal plate otherwise it just would not work and note the deviation in the report. The test isn't "as per standard", but no standard can hope to capture every equipment type and function Regards Charlie Charlie Blackham Sulis Consultants Ltd Tel: +44 (0)7946 624317 Web: https://sulisconsultants.com/ Registered in England and Wales, number 05466247 From: Larry K. Stillings <[email protected]> Sent: 28 January 2020 16:24 To: [email protected] Subject: [PSES] Floor Standing Metal Detector Immunity Testing All, I am wondering if anyone has done immunity / susceptibility testing on Floor standing metal detecting devices. What I think the rub is, all of the test setups are based upon using a metal ground plane for the tests (there are a couple exceptions however, primarily in the 61000-4-x series of standards floor standing equipment is setup on a ground plane with some sort of insulation barrier. The question is, how do you get a metal detector to work reliably when it is in such close proximity to the ground plane and detecting a false positive. More curious than anything if anyone has worked on one of these and has an elegant solution. One thought I had was to line the ground plane with ferrite tile floor / wall panel squares (2' x 2' kind e.g 600mm x 600mm), but where they work at such low frequency I assumed that wouldn't help.
