FIELD: equipment testing geometrical values by electric methods, measurement of metallization area of printed circuit boards in process of electrolytic precipitation. SUBSTANCE: meter includes power source of current, converters of current, voltage, specific conductivity to analog signals and units processing measurement results and converting them to signal of metallization area. Characteristic feature of meter lies in usage of channel measuring area of anode and of second voltage divider correcting results of measurement of metallization area. EFFECT: decreased measurement error thanks to correction of result with due account of change of area of anode. 1 dwg
