When the instrument is driven by a Solar Cell system it is imporant that the internal
battery in the instrument has got enough power to be able to boot the instrument
properly. It is therfor recommended that the instrument powers down at a higher
level than normal. Select 'Solar Cell' if powered by a solar cell system, otherwise
this setting should be 'Normal'.
In addition it might be periods of the day when the instrument
could be turned off due to low noise or other reasons. Set start time to the full hour
for power off, and select how many hours the instrument should be kept off. To ensure a full Global measurement, the instrument
will start a few minutes before required time.
If the number of hous is zero, the instrument will run 24/7.
