Information

The B & K model 290 is a solid state FET input Electronic Multimeter ideally suited for radio and TV service? technicians, industrial users, engineers and hobbyists. Its main features include: • High input impedance (15 megohms) on both AC and DC voltage measurements for minimum circuit loading. • 50 millivolts full-scale sensitivity on both AC and DC volts. • Special low resistance ohms range (one ohm center scale). • Low voltage and normal voltage ohms tests for measuring resistances or for testing IC’s, transistors, SCR’s, etc. in or out-of circuit. • Full AC operation (no batteries) with regulated power supplies for ultra stable operation. • Protection from accidental overloads to meter, FET’s and other circuit elements. • Easy-to-read meter with mirrored scale for making exact measurements.
