8.3 Electrically noisy environments
EMF noise emanating from the ac mains power grid can be a significant source of measurement
error. 60Hz noise is common in the United States. 50Hz noise is common in Europe and other
regions. This noise can usually be filtered out.
The following code snip examples filter 60 Hz noise.
CR6-series data logger example:
Therm107(T107_C,1,U1,U10,0,60,1.0,0.0)
CR800-series and CR3000 data loggers example:
Therm107(T107_C,1,1,Vx1,0,_60Hz,1.0,0.0)
8.4 Long cable lengths
Long cable lengths (>50 ft) may require longer than normal analogue measurement settling
times. Enter a longer settling time in the SettlingTime parameter of the Therm107()
instruction. Campbell Scientific suggests doubling the settling time every 50ft. The following
code snip examples increase settling time by 20000µs by placing 20000 as the argument in the
SettlingTime parameter:
CR6-series data logger example:
Therm107(T107_C,1,U1,U10,20000,60,1.0,0.0)
CR800-series and CR3000 data loggers example:
Therm107(T107_C,1,1,1,20000,_60Hz,1.0,0.0)
