Operation MicroVol-1100 User manual 1.6
3.3.3 Manual Menu
Manual mode is useful for checking the flow-rate and verifying pump
operation. The Manual Menu allows the MicroVol to be switched on or off
independent of other conditions such as programmable timer settings, wind
speed and direction parameters. It is not intended for long-term sampling as it
returns to Automatic mode after the time-out period. The time-out reverts to
Automatic mode after a preset number of minutes, which can be set between 1
and 227 minutes.
Set YES for Manual mode operation
Manual Mode YES
Once in Manual mode, set YES to turn
pump motor on, or NO to turn it off.
Motor On NO
Timeout period in minutes, reverts to
Automatic mode after this time.

3.4 Wind Sensor
The wind sensor may be used for conditional sampling. The data logger automatically
collects wind speed and direction data at programmable averaging periods.
Note: Wind direction data should be
ignored if the wind sensor is not installed.
The wind sensor must be aligned to true north. This is usually done using a hand-held
compass and adjusting for the magnetic declination from true north. Align the mark
on the wind sensor to the specified direction.
Set the wind direction conditional sampling parameters in the Wind menu:
•
Set CCW W.Dir - This is the compass direction of the counter-
clockwise (CCW) end of the ACTIVE sector.
•
Set CW W.Dir - This is the compass direction of the clock-wise
(CW) end of the ACTIVE sector.
•
Also set the Low and High wind speed limits for sampling.
See section 3.3.2.2 for more information on wind menu set-up.
