Congratulations on your purchase of the Extech Model 407001 Data Acquisition Software Package that includes a CDROM and an interface cable. The software is dedicated for use with Extech's Heavy Duty Meter Series. The 407001
software displays data in the following formats: Analog meter, Digital meter (with Max/Min readings), Data List, and X-Y
Graph (for last 100 data points). Data is stored as a text file that can then be opened in spreadsheet and other software
programs.
Hardware Connection
The Heavy Duty meter connects to a PC with the supplied DB-9 to 3.5mm mini-plug (mono) interface cable. The DB-9
end connects to the PC serial com port. The mini-plug end connects to the Heavy Duty meter
.
Software Installation
NOTE: This program may require supporting files that are missing or more recent then those
presently residing in the PC. If an error message appears during installation that indicates an update
is necessary, go to the Microsoft web site (www.microsoft.com) to locate and perform the Windows
Critical Updates and Service Pack Updates for the specific operating system.
1. Insert the supplied software disk in the computer’s CD-ROM drive.
2. Run the SETUP.EXE program included on the software disk.
3. When prompted, select a directory location for the program files.
1. Once the setup is complete, double click the
green DataACQ program icon which resides in
the same directory as the directory selected in
step 3 of the Software Installation procedure
above.
2. The COM SELECT window (shown at right)
opens, prompting the user to select the PC com
port that will be used to connect to the meter
(typically Com 1 or 2). Select SLM Enabled for
Model 407768 Digital Sound Level Meter use
only. Click OK when done.
3. The DISPLAY TYPE window (shown at right)
opens, prompting the user to select the
appropriate meter display configuration (single
or dual display). If unsure, check the Table that lists all of the Heavy Duty meters and their display types later in this
manual. Click OK when done.
4. The DATA_ACQ window opens and prompts the user to click
YES or NO. Press YES if you intend to view readings and save
them in a file. Press NO if you wish to view readings but not save
the readings to a file.
5. If YES was selected in the previous step, the SAVE AS window
appears prompting the user to name the data file and to select a
directory to place it in. The confirmation window appears
showing the new file and its path. Click OK.
6. The DATA COLLECTION window (at right) opens. Refer to steps
a. through d. below:
a. Use the Select Sample scroll bar to select the time between
readings (from 1 second to 60 minutes).
b. Use the Total Number of Samples selection to save a
specific number of measurements. The range is 1 to 10,000
samples.
c. Use the Start/Stop Time fields to define a data collection
time period. The time period is entered in 24-hour format
(HH:MM:SS). The range is 00:00:00 to 23:59:59. Leave blank
to start logging immediately.
d. If both Number of Samples and Start/Stop Time are selected, the recording will begin at the start time and end
when either the Stop time or the Total Samples has been reached, whichever event occurs first. When recording
automatically stops, the FILE CLOSED message will appear on the PC screen.
Automatic Power OFF
Many Heavy Duty Meters have an AUTO POWER OFF feature that turns the meter off after approximately 10 minutes.
This feature must be disabled before starting a datalogging session to avoid having the meter shut off in the middle of a
session. Disable AUTO POWER OFF by pressing the meter’s RECORD key. While the meter is in the RECORD mode,
the AUTO POWER OFF feature will be disabled.
Initiate Datalogging by clicking START in the DATA COLLECTION window (shown on the previous page). The main
program window appears (as shown on the cover of this manual) displaying the Extech logo and the following menu
selections:
File
• Create/Save File: Saves the currently opened file or creates a new file
• View File: Opens a previously saved data file
• Close Current File: Closes the file currently open
• Download Datalogger: Initiates a data transfer from the optional Extech Datalogger
View Mode
• Display Analog: Presents the data as an analog meter.
Note that the Analog display is scaled using the largest reading logged. If changes to the unit of measure are
made or if large changes in readings occur, the display window should be closed and re-opened to reset the
scaling.
• Digital: LED-type display with High and Low Reading fields (diagram below left).
• Display File Count: Provides a tally of data points logged.
• Display Data: Provides logged data in list format
Data Graph
• The graph plots the last 100 data points
• Print Graph: Prints graph to a printer connected to the PC.
• Label 1 and 2 represent the units of measure for the primary and secondary meter displays. Note that some
Heavy Duty meters do not have a secondary display. The Labels automatically recognize the meter’s units of
measure. Labels 1 and 2 are color coded for easy viewing. Press HIDE to close the data graph window.
Important Note: The Recorded High and Low values (shown, for example, in the diagram above left) are the highest
and lowest values observed at any time during the recording period. These values, especially for long sample rates,
may not be the same as the high and low values listed in the data file.
The Extech 380340 Datalogger stores readings from Heavy Duty Meters for later transfer to a PC. The Software
supplied with the 380340 Datalogger should be used to transfer data to a PC (refer to the documentation supplied with
the 380340 Datalogger to do so). To download data using the 407001 software, follow the steps below.
1. Connect the Datalogger to the PC as described in the Datalogger manual.
2. Run the 407001 Software as previously described (select NO in step 4 on page 2).
3. Select Download Datalogger from the 407001 Software FILE menu.
4. Follow the on-screen instructions to download and save the datalogger data.
