Hi, Leong;
there are two ways to "calibrate" the CX clock.
first one - enter the actaul time in the X-register and execute CORRECT at the exact moment this time is reached. CORRECT computes the difference between the internal clock and the value in the X-register, and uses the difference to balance the internal "ticks"
second one - use SETAF (set accurace factor). This function uses the value in X-register to force a "stable drift" and adjust any unaccuraces.
If you have the HP41CX Owner's Manual, Vol. 2, please check pages 238 and 376. If you don't have it, post again and we'll add more info.
Best regards.

Hi GS Leong,
I am sorry but 9 mins per 24 hours can't be corrected by the functions CORRECT or SETAF.
SETAF can correct 84.375 seconds per day with the value SETAF = 0.1
The function CORRECT has the same range as SETAF.
Regards,
Thomas
