Meter Ranges and Measurement Times
Some power modules have multiple voltage and current meter ranges (see Model Differences).
Selecting a lower measurement range provides greater measurement accuracy, provided that the
measurement does not exceed the range. If the measurement exceeds the range, an “Overload” error
will occur.
Measurement Time parameters can be configured for all power modules.
From the front panel:
To specify a measurement range, press the Meter View key, then press Properties.
How the Meter View measurement system behaves depends on whether the standard
controls, or the N6700 Mode controls are selected. N6700 mode controls are selected
in the Front Panel Preferences dialog, located in the Utilities menu.
The standard measurement controls are shown in the Meter Properties dialog on the
left. These controls are completely independent from the measurement controls for
Scope View, Data Logger View, Elog, Histogram, and the SCPI commands.
The N6700 Mode controls are shown in the Meter Properties dialog on the right. In
N6700 mode, the Meter View measurement system uses the same measurement
control settings as set by their corresponding SCPI commands.
Meter Ranges - In the Voltage or Current dropdown menu, select the desired lower measurement
range. Check the Auto box to enable measurement autoranging. The instrument automatically selects
the best measurement range for the amplitude of the measurement. Note that this functionality is not
the same as seamless measurements.
Line Frequency – Specify the ac mains frequency (50 Hz or 60 Hz).
NPLC - Specify the number of power line cycles (NPLC) that the measurement will span. Increase the
NPLC for improved accuracy and noise reduction on low current and voltage measurements.
Duration – Indicates the duration of the measurement based on the Frequency and NPLC settings.
