Hi Bob,
to enter calibration the bottom <Scale & Offset> is to be pressed during
power on.
In my case, CAL SECURE is displayed and after the next push on <Scale &
Offset> the display reads: CODE: 0.
Using left arrow it makes up to 7 zeros to appear... - quite a lot of
options to try it manually... even more pushes needed as e.g. 4 is
reached be 4-times up arrow...
Still hoping to learn the secret procedure.
I've tried several figures (among them 53131 as said in the manual or
the number printed on a paper lable sticking on the display)...
Neither Serial number nor date code is working - always: BAD CODE.
Nevertheless: thanks!

Hi
I believe you will find that when you do the cal it will ask you:
Security yes/no?
(answer yes)
Enter your key?
(enter a random number)
Enter your key again?
(re-enter random number)
Security enabled.
No, that is not a direct quote of what happens. It’s purely a guess based on
the process used on other gizmos.
Yes, there pretty much *has* to be a “wipe the memory” command somewhere. I
would not find it surprising if the answer involves a trip back to HP for
service. I doubt they will do much on a 53131 now that they have killed off
support.
What to do:
1) Try the usual guesses 123, 1234 etc.
2) Try the end of the serial number on the counter
3) Try 53131
Again - only a guess. It does fit the given information - no magic code listed
anywhere / Magic code does exist.
Bob
