Chauvin Arnoux make an inexpensive differential probe, part number DP 25. 1000V input rating with isolation to 61010 and a low voltage 'scope output. www.aemc.com (phone them. Impossible to find on their website)
Jon Francis www.voltech.com From: Wendy Nya [mailto:[email protected]] Sent: 22 June 2005 06:12 To: Emc-Pstc@Ieee. Org Subject: Voltage Dips/Mains Interruption/Voltage Variation Monitoring I am using Schaffner's Profline Series to perform the above mention immunity test. The NSG 2200-1 (AC Switch) does not provide a low voltage signal where I can connect to the oscilloscope to monitor the percentage dip or voltage variations. Please advise me on the following: (1) A suitable circuit which I can easily build to step down the voltage such that I can connect directly to the scope (safely). (2) Or any other alternatives? I have an Agilent infiniium digital scope with a 10:1 miniature passive probe 300V max. Thanks.
