Introduction

Welcome to the User's Guide for the Logging Software, a data acquisition tool that collects, records, displays and analyses measurement data. The software has the following capabilities:

Collects blocks of data at high speed from a single logger Collects data at low speed over long periods from multiple loggers Allows you to adjust Alarm settings for measurements you want to take Enables you to apply Parameter scaling , using equations or tables Allows you to Edit calculated parameters Can analyse other files during data collection Displays data during slow collection and after collection Graphical display in the XY Graph and Graph windows, and spreadsheet display in the Spreadsheet

windows Transfers data to other applications via clipboard, file or DDE Transfers data between computers using IP sockets

1.2

Recording

The recording mode and repeat functions are selected using the Recording dialog. Ensure that real time continuous mode is selected. This offers continuous recording over long periods. The data can be displayed in graphical or spreadsheet format during data collection. The fastest sampling rate in realtime mode depends on the speed of the computer and the operating system (it is of the order of a few milliseconds).

There are several options to specify what should happen at the end of a run when the specified maximum number of samples have been collected. The options are as follows:

Stop Repeat immediately Scroll Repeat after delay

Introduction

1.3

Safety warning

Do not connect the ground input of the converter to anything which may be at some voltage other than ground, as you may risk damage to the converter and your computer. Furthermore, if you connect the converter ground to something which is live, your computer chassis may become live.

If in doubt, check by connecting a channel input to the doubtful ground point, and check that there is no significant AC or DC voltage.

We strongly recommend that you read the general safety information in your installation guide and also the product-specific safety warning in the product manual before using your product for the first time.

2.1

Software components

Introduction

The Logging Software is made up of a number of separate components, but you need only activate the components that you wish to use. As a result, the screen is not cluttered with data that you are not using and the computer can easily be used for other applications whilst you are recording.

The application components that are available are as follows:

Logging Recorder

Enables you to start and stop recording and to specify recording files, the measurements currently being taken and the alarm state.

Logging Player

Enables you to scroll quickly and easily through stored files to compare results on successive runs.

Graph

Shows the readings for single or multiple measurements over a period of time.

XY Graph

Shows the readings of one measurement against another, on the same graph.

Spreadsheet

Shows detailed or summary information in a format which can be copied to a clipboard.

Notes

Enables you to enter information for a particular run. When you start the Logging Software in recorder mode, the computer displays the

Logging Recorder . The Logging Player and display windows can be selected from the Window menu.

When you start the Logging Software in player mode, the computer displays the Logging Player . The Logging Recorder and display windows can be selected from the Window menu.

Software components

2.2

Recorder

When you start the Logging Software using the Recorder icon, the computer displays the monitor window:

At the top is a menu bar containing the File , Settings , View and Help menus. Below the menu bar are two sets of controls, the Recorder controls and the Window controls.

Recorder controls

New file. Specify a new file to record to. Re-record. Rewind the current file so that it can be re-recorded. Start recording. Pause/resume. Stop recording. Help. Access the help information for the recorder window (this page).

20 21 21

Window controls

The second group of buttons, on the right, is used to open other windows:

View Notes. Open a Notes window. View Graph. Open a Graph window. View spreadsheet. Open a Spreadsheet window.

Range indicators

The lower pane of the window contains a line of information for each selected measurement. At the beginning of each line is an indicator lamp that signals the current status of the readings taken by the PT-104 software:

The measurement value is within range The measurement value is currently out of range, but has not been out of range

long enough to trigger an alarm The measurement value is in an alarm state. To cancel the alarm, use the mouse

to click on the lamp

The measurement value is in an alarm state, but the alarm has been cancelled

Next to each lamp is the name of the measurement and its current value. If you click on a measurement name, the computer will display the details of the measurement.

2.3

Logging Player

When you start the Logging Player, or you select Player from the View menu of the Logging Recorder, the computer opens a new window:

This shows you the name of the current Logging Player file and the number of samples taken so far.

Logging Player controls

The buttons on the left are used to specify a filename and to go forwards or backwards in a file sequence. The controls are as follows:

The group of horizontal buttons in the top right corner of the screen selects what time interval is displayed:

Scroll left. Move a whole display left. Scroll quarter left. Move a quarter display left. Expand horizontal axis. Magnify the middle half of the display to fill the whole

width. Shrink horizontal axis. Shrink the current display to half size, so that more is

displayed before and after.

Scroll quarter right. Move a quarter display right. Scroll right. Move a whole display right.

The upper group of vertical buttons controls the vertical range displayed. If there is more than one graph frame, the buttons control the frame with the thicker border. To switch to a different frame, point inside the new frame with the cursor and click the left mouse button.

Scroll up. Move a whole display up. Expand vertical axis. Magnify the middle half of the display to fill the whole

height. Shrink vertical axis. Shrink the current display height to half size, so that more

is displayed above and below. Scroll down. Move a whole display down.

Note that if you use these controls to change the time or vertical range, auto-scaling for that axis is turned off automatically. Use the options to turn auto-scaling back on again (see button below).

The remaining vertical controls are:

2.6

Spreadsheet

From the View menu of the Logging Recorder or Logging Player, select Spreadsheet.

There is one line for each reading. The first column shows the time in seconds, while the remaining columns show the selected measurements.

The following options buttons are available:

Select channels. Select the measurements to display. View options. Spreadsheet options specify whether to display individual

readings, or first reading, average, minimum and maximum for a period.

If you select a range of readings, you can use the following buttons:

Write to disk. Write the readings to a print file (.prn ) or a text file (.txt) -

Both are tab-separated value files.

Copy to clipboard. Write the readings to the clipboard. Print view. Print the graph.

You can select a range in one of three ways:

If all of the readings that you want to select are on the screen:

Point the mouse at the first reading Press and hold down the left mouse button Drag the mouse to the last reading (the selected readings will be highlighted as you go) and Release the left mouse button.

If the readings are a long way apart:

Notes

From the View menu of the Logging Recorder or Logging Player, select Notes.

This window enables you to enter information for a particular run. This is useful if you carry out a number of similar runs. The report title can be the same for every run, but the notes contain information specific to each run.
