1. A TEST CIRCUIT FOR A LOW POWER DIRECT-CURRENT SOURCE COMPRISING:
- A DIRECT-CURRENT POWER SUPPLY, THE VOLTAGE OF WHICH IS GREATER THAN THAT OF SAID LOW POWER DIRECT-CURRENT SOURCE, A SWITCH, A CAPACITOR AND A FIRST RESISTOR CONNECTED IN SERIES;
A SECOND RESISTOR AND SAID LOW POWER SOURCE SERIALLY CONNECTED ACROSS SAID CAPACITOR, THE POSITIVE TERMINAL OF SAID LOW POWER SOURCE BEING CONNECTED TO THE NEGATIVE TERMINAL OF SAID DIRECT-CURRENT POWER SUPPLY SO THAT SAID DIRECT-CURRENT POWER SUPPLY OVER-DRIVES SAID LOW POWER DIRECT-CURRENT SOURCE AS SAID CAPACITOR CHARGES;
AB X-Y RECORDER HAVING FIRST AND SECOND PAIRS OF INPUT TERMINALS;
SAID SECOND RESISTOR AND SAID SECOND PAIR OF INPUT TERMINALS BEING CONNECTED ACROSS SAID LOW POWER SOURCE.
