Smart Meter Verification measurements

The Smart Meter Verification test will make measurements of the coil resistance, coil
inductance, and electrode resistance and compare these values to the values taken during
the sensor baseline process to determine the sensor calibration deviation, the coil circuit
health, and the electrode circuit health. In addition, the measurements taken by this test
can provide additional information when troubleshooting the meter.
