he „scale‟ is the maximum amplitude that will be displayed. Set the scale to be
similar to the rms value to see an overview of the spectrum. To view smaller
harmonics in more detail a smaller „scale may be set.
If the harmonic exceeds the set scale it will be shown with a white cap on the top
of the bar.
The „scale‟ only applies when the harmonic format is absolute measurements. If
percentage measurements are used, then the scale is automatically set to 100%.
The fundamental harmonic (H1) will be displayed as 100%.
The right
and left
arrow keys may be used to select the harmonic whose
amplitude and phase are shown at the top of the screen. The selected harmonic
is shown in yellow.
Select
Show and press

current).
Integration Graph
Select Integration graph using the
keys, press
to configure.
The Integration Graph menu allows the user to select what value to display on the
graph, the vertical scale of the graph (in units of the value selected), and the
horizontal scale (duration) of the graph.
The horizontal scale of the graph is only for display purposes. The integration will
continue until stopped by the user using the start/stop (
/
) button.
When the graph is configured, select Show to view the graph.

9600, 19200 (default) and 38400 are available.
The uses hardware handshaking (RTS / CTS) with no parity, 8 data
bits and 1stop bit (N,8,1).
The RS232 baud rate is unchanged after a “*RST” or “:DVC” command.
