8. Glossary

Active Form:

Refers to the window's dialog box that is currently running.

The active form is the form which has its top window bar highlighted.

Accuracy:

Refers to the level of precision (tolerance) of a measured parameter, typically expressed terms of +/-

value or percent.

Auto Scale:

A graphical function in TrendReader Express which maximizes display of a graph-curve along the y-

axis.

Analog Signal:

The output of a sensor that translates to a current signal (ie: 4 to 20mA)

Analog to Digital Converter:

This component of the data logger takes the sensor information and transforms

the data into information that can be processed into engineering units.

Backup:

To download data from a logger to a computer.

Byte Count:

A basic incremental unit of measurement used on a digital computer.

Calibrate:

Process of adjusting measuring instrument in order to minimize measurement deviation.

Com Port:

A port on the PC (personal computer) through which a computer establishes logger communications.

Comma Delimited:

A file that contains text that has been separated by commas.

Compressed Data:

Data that has been stored using an efficient data-indexing method. A data management

technique which assigns a single number to successive readings with same byte count, rather than assigning each

reading an index.

Data Logger:

A self-powered electronic data-recording device used to measure: temperature, voltage, current,

pulse-signals, etc. A data logger is a modern version of the mechanical chart recorder.

Delay Time:

A feature that allows a data logger to start logging a session at a future time/date.

Desktop Shortcut:

A link created on the Windows desktop that will open a program assigned to an icon.

Dragging:

To move the mouse while depressing a specific button (usually the left button). To drag an object, move

the mouse cursor over the object, depress the button and while holding the button down, move the mouse.

Exporting Data:

A software function used to convert data from its resident file format, into a generic form in order

to make it readable in another program.

FIFO:

First-In-First-Out. When a data logger's memory is full and this option is selected, the first reading will drop in

order to create room for the most recent reading.

Form:

Refers to the windows dialog box.

IC-101:

A product name given to the interface cable used for ACR data loggers.

Icon:

A link on tool bar or on a Windows desktop which functions as a short-cut to an application or operation.

Interval:

The time between data readings.

IP rating:

An internationally recognized standard used to rate ability of a casing against leakage or failure due to

certain conditions. For example: IP67 refers to a device that can be subjected to water for 1 hour at a depth of 1

meter without leakage.
