PA3000 Four-channel, Multi-phase AC/DC Power Analyzer
Energy Consumption Testing
7. To stop the integration, press the INTEG RUN key again; to reset, use the RESET/CLEAR key.
The integrator can be run simultaneously on all groups/channels on the PA3000. While in the
integrator mode, the integration graph can be enabled by pressing
. The graph displays all
integration measurements for a given group. Scroll through the different groups by using the arrow
keys on the front panel. Other parameters to graph can be selected by pressing the INT soft key.
FURTHER SETTINGS IF REQUIRED
Data Logging. The logging feature allows you to log data over time for prolonged efficiency
testing involving load and source sweeps. Use the DATA OUT key to log data to any compatible
flash drive connected to the front panel USB connector. The actual logging interval can be changed
by pressing
and going to I
nterfaces
USB Host Data Out. The log file will be saved as
a .csv file
Ranging. By default the PA3000 is auto-ranging. Auto-ranging is fast and generally unnoticeable,
but might lead to loss of data while the auto-ranging occurs. Using a fixed range while measuring
energy consumption ensures that no data is lost during the ranging process. To set a fixed range,
press
and go to
Ranging
Current Range, and then choose a suitable fixed range, based
on the measurements made during auto-ranging. If the range is too low, a warning message
will display. This will not harm the PA3000. The range should not be set too high as this will
compromise the overall accuracy.
