Ranging. By default the PA3000 is auto-ranging. Auto-ranging is fast and
generally unnoticeable, but might lead to loss of data while auto-ranging
occurs. Using a fixed range while measuring standby power ensures that no
data is lost during the ranging process. To set a fixed range, choose Inputs →
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.
Bandwidth. For low power standby signals that have undesired high frequency
components, low bandwidth filters can be enabled. A low bandwidth 10 kHz
filter is available through the Inputs setup. Applying low pass filters might vary
the RMS values of voltage, currents, and power as high frequency components
affect the RMS values.
Autozero. Use the Autozero → Run Now function under the System
Configuration menu to run autozero before running a standby power test. This
will make sure that all the offsets are compensated and the low current and power
readings are accurate.
All settings can be saved for later use in the User Configuration menu.
The PWRVIEW software along with PA3000 can test the standby power using full
compliance techniques of IEC 62301 Ed. 2.0 / EN50564. Measurements are made
easy by using the PWRVIEW software and for making accurate measurements for
full compliance standby testing. The software calculates real time instability and
exectutes power averaging as required by the standard.
