EIP 575 powermeter (OPT 02) calibration
(1/1)
dxl:
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  |................|

--- 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!
