Abstract

1275467 Flame ionization detector circuits HEWLETT PACKARD G m b H 1 Aug 1969 38536/69 Addition to 1274456 Heading G1N The flame ionization detector of the parent Specification (Division H1) is connected to a circuit including an indicator 83 connected in series with the field electrodes 28, 54 a variable resistor 79 and voltage source 81, and a second voltage source is connected across the variable resistor in opposition to the source 81. The variable resistor may be movable step-wise and have a digital indicator of its position.
