3.2 Creating a Measurement Data Log File
Upon clicking the Run button, a File Write dialog box appears. The GUI stores retrieved measurement
data to a file for post processing. Enter the desired subdirectory and file name. Click OK to launch the
main GUI display.
The measurement data is stored as text characters delimited by commas. Click the Stop button to close
the text file and end the data logging function. New data log files are created wherever the Run button is
clicked. The data log capture automatically stops after 12 hours. 12 hours of data results in a 12 MB file.
To import the data log file into Excel, see
3.3 Selecting the Power Display Parameter
Using the Watts Selection menu under OMU Control Modes, select Watt, VA or VAR as the power
display parameter.
Real power is the time average of the instantaneous product of voltage and current (Watt).
Apparent power is the product of rms (root mean square) volts and rms amps (VA, volt-amps).
Reactive power is the time average of the instantaneous product of the voltage and current, with current
phase shifted 90 degrees (VAR, voltamps reactive).
