Hi Forum, i converted my EIP 575 a few years ago to have the power meter option. However, i never recalibrated it. I now wanted to do that, as i just learned that the procedure is described in the 545A manual. However, there's one thing i don't understand. The manual states on p02-6: --- Code: --- 4. Using the following formulas, justify the correction to a number between 10 and 20. .... 5. Program the corrections in these locations. 0000-0005 inclusive 0032-0037 inclusive 0064-0069 inclusive --- End code --- Looking at a real rom image (6400002-04H_Power-Meter_A107.BIN) i see: --- Code: ---00000000 13 13 13 11 12 12 13 14 14 14 15 15 15 16 17 18 |................| 00000010 1a 1a 1b 1b 1b 1c 1d 1e 1e 21 23 26 29 2e 31 3c |.........!#&).1<| 00000020 42 46 4d 53 5b 63 6b 73 7b 83 8b 93 9b a2 aa b2 |BFMS[cks{.......| 00000030 ba c2 13 13 13 11 12 12 13 14 14 14 15 15 15 16 |................| 00000040 17 18 1a 1a 1b 1b 1b 1c 1d 1e 1e 21 23 26 29 2e |...........!#&).| --- End code --- Which isn't what i expected - from the text above was assuming bytes 0000-0005 are all the same values, but apparently they are not. Anyone here know how these values are generated? Thanks! Sven |
