The DMS-40PC's simplified schematic, shown in Figure l, can be very useful when debugging a malfunctioning circuit, especially if the user has some knowledge of operational amplifiers (op amps). The meter's high-impedance input consists of an op amp powered from a +5Vdc power supply (the -5V is internally generated). Figure 1 shows that input signals applied to (-) INPUT LO and (+) INPUT HI must to be kept within the +5V power-supply rails. Also note that only pin 11 has a current-limiting 909k I series resistor. High input voltages that have a common ground connection with pin 3 (5V RETURN) should only be applied to pin 11+) INPUT HI) and never to pin 12. In these high-voltage cases, pin 12 should always be tied to pin 3 (5V RETURN).
