I tried a lot of other "write" commands but that was pointless, it has no effect on the power supply. And every query commands I tried ended up with timeout error (excepting " *IDN?"). Do you have any idea why this does not work for MP710509? I suspect a brand new command definition for this product (and I cannot find any documentation on the web!). Or maybe that is because it is a multi-channel power supply and I don't know how to handle the specificities of this kind of product. Thank you very much!</description></item><item><title /><link>https://community.element14.com/challenges-projects/project14/test-instrumentation/b/blog/posts/working-prototype-of-a-kelvin-4-wire-milliohm-meter?CommentId=c8a58ba5-a46a-440c-a1e6-6404d614183b</link><pubDate>Wed, 05 Apr 2023 02:09:00 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:c8a58ba5-a46a-440c-a1e6-6404d614183b</guid><dc:creator>jdceletronica</dc:creator><description>muito interesante , mais ten algun amigo que ja feis con arduino nano e que tenha todos os componentes aky no brasil ?</description></item><item><title /><link>https://community.element14.com/challenges-projects/project14/test-instrumentation/b/blog/posts/precision-analog-opto-isolation-amplifier-using-hcnr200-201?CommentId=25d46e4e-2e36-42d0-a678-7687cc21e7b3</link><pubDate>Thu, 28 Jul 2022 12:59:00 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:25d46e4e-2e36-42d0-a678-7687cc21e7b3</guid><dc:creator>VictorKhan</dc:creator><description>Hi Hassan, I need to measure 0-60 V analog input signal what are the modifications I need to make to suit my requirement.
