The MINI-LAB provides seven independent instruments in a single compact cabinet for use in the laboratory or classroom to supply signals and power for a wide range of measurements and experiments in the fields of electronics, chemistry and bio-medical engineering. The functions available include: Sine, square, triangle, pulse and ramp generator with variable symmetry and D.C. offset controls producing a wide variety of waveforms from 0.001 Hz to 1MHz which can be amplitude and frequency modulated by an external signal. A ramp generator 5 sec to 50m sec. A switched power amplifier/bi-polar power supply/5 Volt supply combination. An operational Amplifier with variable gain. Two variable power supplies -1 to -15V and +1 to +15V at 1 Ampere output. A 0 to +200V variable power supply. A centre tapped 12.6V A.C. supply, and Numerous instrument combinations by link interconnection.
