And your reason for presuming the "actual current" at 23 A is ????. What are you using to measure that? The meter on your power supply? A Fluke meter that has a 25A range or ?
First calibrate ADC REF on the K3 CONFIG menu (TECH MD must first be set to "on") per the procedure on page 53 of the manual. You can scan for the manual's pdf file for ADC REF . This calibration sets up a reference voltage inside the K3. But do it with an accurate DVM. Then see what the K3's internal shunt voltage is reading. That's what you are actually seeing. 73, Guy.

My K3 meter reads about 20A, when the actual current is 23 A, with > no accessories connected. That's a huge error, and it's not linear. > > 73, > > Scott K9MA > > > > > Scott Ellington > Madison, Wisconsin > USA > > > > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:[email protected] > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
