sets the aperture time to 0.333ms.

to 1.66667 seconds (60Hz) or 2 seconds (50Hz).
•
Setting the aperture time also sets the integration time in power line cycles
(PLCs) and the resolution. For example, an aperture time of 16.7ms (60Hz line
frequency) sets an integration time of 1 PLC. The corresponding resolution
depends on the function and range you select.
•
The VOLT:APER command overrides the results of previously executed
VOLT:NPLC and VOLT:RES
priority.
•
The greater the aperture time, the greater the normal mode rejection (and the
lower the reading rate).
