Label

If you are working with more than one data logger, label each logger, identifying the task and

location before you distribute them throughout a building or system.  To do this, you can simply

use a shipping tag.  Later, when you retrieve them to graph their data, you will know what each

graph refers to.  There is a description field in the Setup that can be used for entering the tag

information.  Note that after editing and saving the Description you will need to click Contact to

update the new Description in TrendReader Explorer and in the Diagnostic Log.

Mounting

Use the magnetic backing to conveniently mount your logger on metal surfaces like ductwork

or electrical control cabinets.  If you are concerned about theft take advantage of its small size

and hide it completely out of view.  Because JR-1000/1001 loggers are so light, you can use

special mounting fasteners like Velcro® to attach them to almost any surface.  Make sure your

logger's mounting method will last the full length of your logging session.

Do not rely on the logger's magnetic strip for adhesion if the mounting surface is uneven,

unstable or above 65°C (150°F).

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 JR-1000/1001 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 backup the data to be analyzed.

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 JR-1000/1001 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.
