6.13 SMART Meter Verification measurements
The SMART Meter Verification test will make measurements of the coil resistance, coil
signature, and electrode resistance and compare these values to the values taken during
the sensor signature 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.
Coil circuit resistance
The coil circuit resistance is a measurement of the coil circuit health. This value is compared
to the coil circuit resistance baseline measurement taken during the sensor signature
process to determine coil circuit health. This value can be continuously monitored using
continuous SMART Meter Verification.
Coil signature
The coil signature is a measurement of the magnetic field strength. This value is compared
to the coil signature baseline measurement taken during the sensor signature process to
determine sensor calibration deviation. This value can be continuously monitored using
continuous SMART Meter Verification.
