Portset(1,0)
In the CR1000, CR800, CR850, and CR3000 dataloggers, use the Portset
instruction.

Portset (1,1)
Delay (1,500,msec)
Portset (1,0)
The above example is not as power efficient as possible and would require AC
power to maintain a sufficient battery charge. If it is necessary to operate an
agitator without AC power available, write the program so that the agitator is
only operated for a short period of time just before the measurement is to be
taken.
