Datalogging
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 in x-y graph format (diagram below right).
• 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.
