Siting the DataRAM

The DataRAM should be placed at least 3 feet off the ground

and away from obstructions (such as trees or buildings) that

may influence airflow. It should be in an area where it will not

be influenced by road dust, industrial pollutants, or other sources

of particulate that could increase its readings.

The DataRAM should usually be sited several miles downwind

of the burn in areas of greatest interest, such as communities or

protected areas. The best use for the DataRAM is to determine

whether the local particulate concentration is relatively high or

low, and whether concentrations are going up or down. Acquire

ambient background particulate concentrations before the burn

to determine clean background conditions. If the instrument is

to be left unattended, place it in the weather-resistant shelter.

Be careful to insert the uncapped inlet port through the hole

in the

shelter. Once the DataRAM is in the shelter, place the

heater,

2.5-micrometer cut-point device, and omnidirectional

inlet on the DataRAM inlet port. The DataRAM power charger

and power strip can fit inside the cover behind the instrument.
