The measurement results of
barometric tendency do not
seem correct
Barometric tendency is calculated based on the measurement results of
atmospheric pressure over the last three hours (automatically
measured approximately every 10 minutes). Depending on the
automatic measurement timing, barometric tendency may not be
calculated correctly.
U
“Notes and Mechanism on Measuring Barometric Pressure” on
When an altitude difference occurs due to movements to different
heights, barometric tendency may not be calculated correctly.

The small second hand does
not stop
