Communicates with JLD416PVA meter over MODBUS RTU. Sends one read command to interrogate all six holding registers of the unit. Also parses the response into voltage, current and power with meaningful units. Includes a sample script to repeatedly poll the device for the measurements. Screenshot was developed measuring a 50/100/150 W three-way lamp.
