NOTE:
Short Cut
cannot edit programs after they are imported and edited in
CRBasic Editor
.
A
Short Cut
tutorial is available in
(p. 2). If you wish to import
Short Cut
code into
CRBasic Editor
to create or add to a customized program, follow the procedure in
Short Cut code into CRBasic Editor
(p. 14). Programming basics for CRBasic data loggers are
provided in the following sections. A complete program is provided in
Programming basics and programming examples for Edlog data loggers are provided at

7.2.1
VoltSE()
instruction
The
VoltSE()
measurement instruction programs the data logger to measure the 27106T.
VoltSE
(Dest, Reps, Range, SEChan, MeasOff, SettlingTime, Integ/fnotch, Mult,
Offset)
For
Range
, use
mV2500
(CR300, CR1000) or
mV5000
(CR6, CR1000X, CR3000). If the
anemometer will be in electrically noisy environments, use 50 Hz or 60 Hz rejection for
Integ/f
notch
.
7.2.2 Multiplier and offset
The expression for wind speed (U) is:
U = MX + B
Where,
M = multiplier
X = voltage measured by the data logger
B = offset
(p. 8) lists the multipliers to obtain miles/hour, meters/second, km/hr, and knots. The
helicoid propeller has a calibration that passes through zero, so the offset is zero.
