Does anyone know at what point the ppm display under Setup — Settings gets updated, after changing the rtccalib.cfg file?
I've just edited my file, changing from -21 to -22, but the display is still showing -21ppm.
I've double-checked the file content (on a PC), turned the DM42 off/on a few times: still the same.

Re: RTC Calibration program
The values in /rtccalib.cfg aren't quite in ppm. The PPM value is about 95.3674% of the calbration value.cdmackay wrote: ↑Sun Apr 12, 2020 10:38 pmDoes anyone know at what point the ppm display under Setup — Settings gets updated, after changing the rtccalib.cfg file?

Re: RTC Calibration program
I tried to run this calc after I loaded the raw into my DM42 but I end up with “Invalid Data” after I’ve entered date, drift and previous value.
I also ran the raw on the iOS Free42 but ended up with the same Invalid Data.
Am I missing something obvious?

Re: RTC Calibration program
Perhaps you are entering the date in the wrong format? The expected format depends on which of DMY, MDY or YMD you have set in the MODES menu.
Re: RTC Calibration program
Yes indeed you were right.
The Free42 required the date format: YYYY.MMDD
While the DM42 wanted it: MM.DDYYYY

Re: RTC Calibration program
It is not an inherent difference between the 2 platforms, you simply have each platform set to use a different format.
See the DMY and MDY command descriptions here:

Re: RTC Calibration program
I should add that Free42 sets the date format to match the host system's locale. It does this during cold start, i.e. when you see Memory Clear.
This means that, for example, the initial setting in the U.S. will be MDY, while in the Netherlands it will be DMY, and in Japan it will be YMD.

Re: RTC Calibration program
Thanks for clarifying this Thomas, I never knew that. The DM42 clearly can't do that, instead it obviously uses the setting from the User in the SETUP menu, which I think defaults initially to HP's 42S default of MDY.Thomas Okken wrote: ↑Thu Jul 28, 2022 5:24 pmI should add that Free42 sets the date format to match the host system's locale.

Suggestion: Add this note to the Free42 "#time" section of the notes.
