Further Details:

Systronics AC Mcro/Milli Volt Meter 401 is a solid state precision instrument, measurng AC Voltages from 10µV to 500 V r.m.s. over a frequency range of 1Hz to 3MHz. Designed for easy operation, the instrument gives direct reading of voltage or dB on diital display.

The unit uses a stable, high gain AC amplifier, which delivers essentially, a hum free, low noise micro phony signal output. Operated on mains, this test instrument is sturdily constructed and is enclosed in an elegan metallic cabinet with a pair of rugged, plastic moulded, dual position stands.
