  • Model 7 Universal AvoMeter MKII.

    New movement design but no external changes initially. At some point during the 1950's, added power factor jacks for P.F. unit and red and black banana terminals in 1956. Last manufactured 1986. 

    Ranges;

    CURRENT: A.C. and D.C. 0 to 10 amps. 
    VOLTAGE: A.C. and D:C. 0 to 1,000 volts.
    RESISTANCE: Up to 40 megohms. 
    AUDIO-FREQUENCY POWER: 0-2 watts. 
    CAPACITY: 0.01 to 20 mFds. 
    DECIBELS: -25dB to + 16dB.

    POWER FACTOR AND POWER can be measured in A.C. circuits  by means of an external accessory (the Universal AvoMeter Power Factor and Wattage Unit). Two models of this Unit are available, one for use with the Model 7 Avo Meter and the other with the Model 40 AvoMeter, but in either case the Avo Meter must be a model fitted with sockets marked "P.F." for connection to the Unit. All recently produced Avo Meters have been fitted with these sockets.

Altersbestimmung:
Gemäss einem Hinweis eines RM.org Besuchers auf die Internet Seite www.richardsradios.co.uk lässt sich die Altersbestimmung bei den meisten AVO Geräten mittels der Seriennummer (bei den Instrumenten rechts auf der Skala unten) machen.
Die letzten 3 Ziffern bezeichnen den Monat und das Herstellungsjahr.
Beispiel S/N 49005-A-954 bedeutet Herstellung im September 1954.
