Claim 1
Independent Claim
138 words
A VOLTAGE TESTER CIRCUIT INCLUDING A PAIR OF INPUT TERMINALS, A PLURALITY OF INDICATORS CONNECTED IN SERIES ACROSS SAID INPUT TERMINALS, RESISTANCE MEANS CONNECTED IN PARALLEL WITH AT LEAST SOME OF SAID INDICATORS FOR ACTIVATING THEM AT DIFFERENT INPUT VOLTAGES, A RESISTIVE-CAPACITIVE COMPENSATING NETWORK CONNECTED BETWEEN SAID INPUT TERMINALS AND AT LEAST ONE OF SAID INDICATORS, SAID COMPENSATING NETWORK APPLYING A D.C. VOLTAGE FROM SAID INPUT TERMINALS DIRECTLY ACROSS SAID ONE INDICATOR WITH NO REDUCTION IN VALUE FROM THE AMPLITUDE AT THE INPUT TERMINALS, SAID COMPENSATING NETWORK APPLYING AN A.C. VOLTAGE FROM SAID INPUT TERMINALS ACROSS SAID ONE INDICATOR AND REDUCING THE A.C. VOLTAGE APPLIED ACROSS SAID ONE INDICATOR TO A VALUE GENERALLY EQUAL TO THE R.M.S VALUE OF THE INPUT A.C. VOLTAGE, THEREBY PROVIDING GENERALLY THE SAME VOLTAGE AMPLITUDE AT SAID ONE INDICATOR FOR BOTH A.C. AND
