DEMONSTRATION GUIDE
PA3000 Four-channel, Multi-phase AC/DC Power Analyzer
Standby Power Measurements (IEC 62301 Ed 2.0)
METHOD 1: STANDBY POWER QUICK CHECK (PA3000 DIRECT)
The front-panel mode of the PA3000 is designed to give product designers a fast, yet reliable,
check of standby power consumption. Enabling standby power mode automatically sets a long
averaging time to average the typical power variations and bursts and it disables low-level
blanking so that very low power and current values can be displayed.
NOTE: The PA3000 samples continuously in standby mode to ensure that no data is lost.
If the expected standby current is lower than 1A, select the 1A shunt input of the PA3000.

FURTHER SETTINGS IF REQUIRED
Integration time window. The default integration time is 10 seconds. This can be adjusted as
required in the
Modes
Setup Modes
Standby Setup. If the DUT is stable, select a shorter
time for faster measurements. If the measurements are unstable, choose a longer integration time.
If in doubt, use the full-compliance method built-in to the PWRVIEW software.
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.
