Solid State Electronic Multimeter
Informatie
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.
