Bases: rx, context_manager, attribute
The AD-PQMON-SL is a power quality monitoring solution based on the ADE9430,
which is a high performance, polyphase energy and Class S power quality monitoring
and energy metering device.
-
class config(ctrl, channel_name)
Bases: attribute
The config class is used to configure the AD-PQMON-SL device power analysis
parameters as required by the ADSW-PQ-CLS library
This class also implements the process_data attribute which is used to enable
power quality measurements (when set to true) or waveform measurements (when set
to false)
The single_shot_acquisition attribute is used to enable single shot acquisition
(by default True). When this attribute is set to False, the device is set up for
continuous acquisition and it will not reset the process_data attribute between
acquisitions.
