Measurement:

Apply the gasket attached to the cell to the coated surface to limit the coulometric area and jinject an electrolyte suitable to the coat and substrate into the cell. Set the objective substrate in the anode and cell in the cathode. Then, apply an accuracy adjusted current to the caot to melt it. The voltage across the anode and cathode called as "coulometric voltage" is rapidly changed under such situation that the coat metal is being fully melted, results in an exposure of the substrate. The thickness of the caot is calculated for this change in the coulometric voltage and period of time form the start of the current to the end of the above voltage change measurement.

Maintenance:

In order to maintain accurate measurement for long time, a yearly periodical maintenance including clibration should be recommended.

Deterioration of the backup battery leads the cease of the clock funtion even if the measurement circuit operation is normal. The battery should be replaced every five years at the maintenance.
