Function overview
When recording the temperature and humidity on the chart
paper, those two traces inevitably have the di erent time
axes due to the positional di erence of the recording pens.
Use this function to compensate the distance and align the
time axes.
Reference
The table below shows the reference between the
chart speed and time required for the two traces to
synchronize (agree with each other) in time axis.
