Note
• When the output items are to be sent by communication interface and they are set to V, A, P or dEG,
these items are then output. When the output item to be sent by communication is set to ALL, not only
the V and A data are output, but P and dEG data as well. When the output item to be sent by
communication is set to G-V to CG-P, the output data will not be the graph, but the numerical values.
• The orders are printed up to the maximum analysis order.
• When the fundamental frequency lies outside the measurement range of the harmonic analysis (display B
will show FrqEr), an attempt to output will result in an error code.
• When you set an element which is not the element of measurement (column B), an attempt to output will
result in an error code.
• When no analysis data are present, "––––" will be printed.
• There are cases where the active power value becomes negative. The corresponding bargraph will be
printed in thin print.
• When no plotter is connected, output time-out will result in an error code.
Example of Output to an External Plotter
• Output example in case of output item G-V of harmonic analysis data
(Slight differences may exist due to used plotter, etc.)
