Abstract
PURPOSE:To check a circuit substrate simply, by connecting respective corresponding check positions of the substrate to be checked and of a reference substrate and by applying an AC voltage across both check positions to detect the output level of the connection point. CONSTITUTION:A substrate to be checked and a reference substrate having a standard network are prepared, and swtiches S1-S4 are provided which select respective corresponding to check positions TP0-TPn-1 and TP0'-TPn-1'. For example, when the check positions TP1-TP3 of the substrate to be checked and the check positions TP1'-TP3' of the reference substrate are selected, AC voltage V1 is applied from an oscillator 1 across the check positions TP1-TP3', and AC voltage V0 is taken out from the connection point of both check positions. These voltages are converted to DC voltages by AC-DC converters 2 and 5 and are compared with each other; and if V1=2V0 is true, it is discriminated that there are nothing abnormal about there check points. This operation is repeated successively to check the circuit substrate including a capacitor, etc. simply.
