To understand how the AC current transducer can measure AC current, please refer to
for a complete
understanding of this measuring technique.
Below are some important configuration parameters which affect the operation of the device like battery life,
measurement accuracy, and alert threshold.
For Battery life estimation, please refer to this link.
measure_period | Default = 600s
This is the time period for the wireless transmitter to wake up and take the measurement from the transducer.
The default value is 600s. Users can reduce this value, but smaller value, shorter battery life!
cyclic_data_period | Default = 600s
Interval time to send an uplink message regardless of any conditions
sensor_boot_time | Default = 1000mS
This value will affect the measurement accuracy.
DO NOT change this value!
Those configuration parameters can be changed by downlink or offline tools. For more other configuration parameters,
please refer to the next section.
Sensor configuration can be configured in 02 methods:
Method 1: Configuring via Downlink message. Please find the instructions in
, but please take note of
the
FW version of the Document.
.
Some parameters are read-only, and some are read and writeable.
To read the parameters, use the off-line cable as above instruction.
Via uplink message, users can read only one parameter, which is the CURRENT_CONFIGURATION.
Below tables are the lists of the parameters of the device.
