Nominal here means: a general, descritive term or design parameter. It is
not tested and not covered by the product warranty.
The Nominal Output displayed on the bottom right side of the display
indicates a range of low and high power values. Your actual measured
output power could be a little lower or a little higher.
If you have the USB power sensor feature (Option 302) you can measure
the actual output power for your measurement. Refer to “Power Meter
Mode (Option 302)” on page 11-1.
