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.
