SmartReader Plus Data Loggers

Cold or Humid Environments

Make sure that the environment you will be placing your logger into will be acceptable by

referring to the Specifications in this chapter. If conditions are not adequate for the logger,

consider using a protective enclosure. For humid conditions you can protect your logger

simply by placing it in a zip-lock plastic bag.

When you place your SmartReader Plus 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 moisture 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

Make sure you 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 Plus 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.
