Information

As the state of the art in electronics progresses, more transistors, FETs, and integrated circuits are being used in radio, television, and industrial markets. Sencore engineers have kept up with todays pace and have developed a new Field Effect meter to meet the more demanding requirements of solid state and integrated circuit servicing. The FE20 HI-LO meter features new low AC and DC ranges of . 1 volts full scale and alow power ohms circuit allowing for the first time accurate re sistance measurements in transistor and integrated circuits. Just compare these features and see why the FE20 is the most advanced meter on the market today: * High input impedance on all AC and DC ranges (15 megohm DC, 12 megohms AC). * True peak to peak AC ranges. * Zero center ranges on DC for solid state servicing. * Db scale for audio and lab work. * DC current ranges for general testing. * Low power (low applied voltage) ohms ranges for solid state servicing. * Mirrored scale meter for greater accuracy in readings. * Meter protected from overloads. * Circuits protected from accidental application of wrong voltages. * All steel carrying case with cover for greater durability and portability. * Long life "C" cell power.
