LPT port:

A parallel communications port used with a printer device.

Modem:

A communications device that transfers information from the logger over a telecommunications network.

Port:

Please refer to Com Port.

RS-232:

A communications protocol by which electronic information is sent and received.

Resolution:

The smallest increment a data logger is capable of segmenting a given range of a sensor. For

example, an 8-bit logger is capable of segmenting a range by 256 increments. In a given range of -40 to +85 deg-C,

span = 125, divided by 256, resolution = 0.49 deg-C.

Sample Interval:

A time increment in which the data logger will take a reading.

Sensor:

Device that transforms one signal to another (ie. temperature to voltage).

Status Bar:

The area at the bottom of an active Windows program that will provide a summary of status related to

the program.

Stop When Full:

A data logging sampling function, which when selected, the data logger will stop recording after

its memory has reached its capacity.

Tab Delimited:

File that contains text that has been separated by tabular keys (tabs).

Text Box:

A field on a form that displays text and allows text entry and editing.

Thermistor:

Temperature sensors are made of semi-conducting material which changes its resistance values

when subjected to different temperatures.

Tool Bar:

A group of ICONS located at the top of the ACR TrendReader Express application window. These

ICONS are shortcuts to frequently used functions within the software.

TRW File:

A standard file format for all ACR data logger files that are created by ACR data loggers.

USB port:

Please refer to Com Port.

Zooming/Unzooming:

The process of increasing/decreasing field of view on a given area on a graph.
