 Parameters are from "Metal x" groups.
 * '''dV''' - the response of the system to the metal.
-* '''th''' - sensitivity detection setting. The parameter values are selected based on the noise level (0.5 .. 0.01).
+* '''sense th''' - sensitivity detection setting. The parameter values are selected based on the noise level (0.5 .. 0.01).
 * '''period ave''' - a rough estimate of the period of oscillations in the circuit (in the system clock cycles 50..4320).
-* '''period min (ticks)''' - the minimum period of oscillations in the loop. For normal operation of the metal detector, it is necessary to fulfill the condition: '''''period min''''' < ('''''period ave''''' + 50).
+* '''period set (ticks)''' - the setted period of oscillations in the loop. For normal operation of the metal detector, it is necessary to fulfill the condition: '''''period min''''' < ('''''period ave''''' + 50).
 * '''dfreq''' - delta of measured frequency and estimated ('''period ave''') frequency.
 * '''statistic''' - oscillogram of frequency measurement statistics results. For best performance it is recommended to beat the '''period ave''' that the maximum of '''statistic''' was in the middle of the graph .
