Hi J-F, It was sent in one command, OUTPUT :1;"B3"&A$. The last nibble was also 0x40. I also loaded Paul's data, unmodified, and it cleared my Cal RAM error. Note, MarkL at EEVBlog has observed that the first nibble indicates the state of the Cal Enable switch. 0x40 = Disabled and 0x4F = Enabled. http://www.eevblog.com/forum/repair/hp-3...-cal-sram/ Dave |
