Boveda Hygometer Calibration Kit usage?

Ok... sounds simple, but raises another question...
I have a XiKar hygometer which only has one button which calibrates to 75% once pressed. No other adjustments.

You state I should calibrate to 75% first after putting into the Boveda bag and press again after the 24 hours? Twice?
