SOFTWARE OVERVIEW AND TAB CONTROL
The software has three tabs at the top that correspond to three different frames in the
main screen.
The results frame shows the power readings coming back from the meter, such as
active power, apparent power, RMS current and RMS voltage.
The log frame shows the message logs that are used to record all activity that is taking
place inside the software during calibration, reading, writing registers, etc.
The communications frame shows all USB activity that takes place during calibration
or meter reading. This can be used to track activity and generate customized meter
calibration scripts.
Note that at software start, the program polls to see if the meter is connected to the PC
via USB. If the meter hardware is found connected (or not connected), an appropriate
message is placed in the scrolling message/status window, e.g. “Meter not connected
(PID0x0xx)”, and the icon in the bottom right hand corner of the results window is
turned red. When a meter is connected, the icon is green and the software refreshes
all visible registers and calibration icons.
