.....................................................................................................................................487 Technical information
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
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:
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.
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.

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.
From the View menu of the Logging Recorder or Logging Player, select Graph.
Note that there are several graph options that affect the way that the graph is
displayed and the format of the axis scales.

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).
Copy to clipboard. Copy the graph to the clipboard.
Print view. Print the graph.
New file. Write graph to file in .bmp, .jpg, or .wmf format.

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.

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.

Point the mouse at any reading during the required day
Click the left mouse button (this will highlight the reading) and
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.
If you have a Notes window open when you use the player to browse through several
runs, the notes for each run will be displayed. The notes also appear on printed
reports.
