consider using a protective enclosure. For humid environments, you can protect your logger
simply by placing it in a zip-lock plastic bag.
When you place your SmartReader logger in a cold environment, make sure condensation will
not settle on the logger when you bring it back into warmer surroundings, such as an office.
The best way of preventing condensation is to place the logger in a container and include a
desiccant (a material that absorbs moisture). When you bring your logger back to your
computer, leave the logger in the container until it has had a chance to warm up to the
surrounding temperature. You can then take it out and analyze it.
Keep Track
Be sure to keep a record of where you have placed each logger in a building or system plan.
You will save time looking for them when your data gathering session is over. Also, keep track
of when you placed the loggers in the area you are monitoring. This will help when producing
graphs on your computer. It may be helpful to label (shipping tag) each logger so you can
properly identify and differentiate it from other loggers.
Analysis
After sufficient time has passed for the logger to obtain a representative profile of data, it is
time to analyze the information. If you are retrieving the logger from the field, bring it back
immediately to your computer for analysis.
In order to analyze your SmartReader logger's data, you must first transfer a backup copy of
its data to your computer. To do this, see Backup in the TrendReader Guide. After
transferring your information to the computer, the data is automatically copied to disk and time
and date-stamped.
You can find a detailed description of all software functions in the TrendReader guide.
