All the recorde
d data is stored in a database on the local computer. To access
the data, click the Results tab and then click the Measure icon. The dialog
box will present all the archived data.
Select the desired data set and export to either an Exc el or a .csv format.
Custom limits. Custom limits can also be set with any of the measurement
parameters. Custom limits help set limits based on various standards or test
specifications.
To set custom limits, either right-click the desired measurement parameter or
click the Limits Setup icon on the menu bar. Stop the measurement update to
set up cus
tom limits.
Custom limits will appear as a separate tab on the measurement grid. The
result c
olumn will display red fonts if the limits are failing. Hovering over the
results will display the limit function, limit value, and relative value.
Example 3: E nergy consumption testing
Energy consumption testing on home and office appliances is required for
compliance to many international and regional standards programs such a s
ENERGY STAR
®
. Energy consumption testing involves the integration of power
consumed over a long period of time, often days. Use the dedicated Integration
Mode on the PA3000 to make energy consumption testing easier and faster.
Meas
urement challenges
Energy consumption testing is often done over a wide range of loads and requires
an accurate measurement system that can capture all dynamic load changes. If the
load is expected to have several load variations, Tektronix recommends to set up
th
e PA3000 in manual range.
Measurement solutions
The Integrator mode on the PA3000 integrates desired measure ments over
aspecified period. Integrator mode enables measurement options such as
W
att-Hours, VA-Hours, Amp-Hours, and Hours under the Measurements menu.
Integration measurements are on a per-group basis and can be enabled for single
and three phase configurations. Detailed information on integration setup and
all available measurements is covered under the Integrator mode section in this
manual. (See page 43, Integrator mode.)
Test Setup
The following steps describe the process to set up energy consumption
measurements on a home or office appliance using a PA3000. This method can
be used for testing energy consumption of any DUT that plugs into the AC wall
socket for power.
