Wind Speed
You may change the wind CAL to adjust the wind speed readings according to
the equation shown below. If you change CAL for wind speed, any calculated
data which uses wind speed (wind chill, for example) will also be affected.
Calibrated Wind Speed = Revolutions * (1600/CAL)
Default CAL = 1600 (for mph), 995 (for kph), 1843 (for knots), or 3578 (for m/s).
Rainfall
Rainfall CAL determines how much rainfall each increment (pulse) represents.
The default rainfall CAL of 100 works for a 0.01” increment.
Calibrated Rainfall= # of pulses * (1/CAL)
Default CAL = 100 (for 0.01" rain collector).
If you use a rain collector which measures in a different increment, or if you
wish to display rainfall in a unit of measure other than the rain collector’s
native unit of measure, consult the table below to determine the correct calibra-
tion number for your purposes.
Note:
Rainfall CAL must be a whole integer (no decimals). Generally, if the Health EM is set to display rain-
fall in a unit of measure other than the rain collector’s “native” unit of measure, you would be
required to enter a CAL number which was not a whole integer. Therefore, we STRONGLY advise you
to always set your Health EM to display the rain collector’s native unit of measure before entering,
changing, or viewing rainfall CAL. Failure to do so may result in inaccurate rainfall readings. Be
aware, however, that no so long as have the correct rainfall CAL for your rain collector, the
Health EM will accurately convert rainfall amounts from inches to millimeters (and vice versa).
