    A clearly marked 5 in. ( 127mm ) scale has uniformly divided graduations to match 100 and 250 scale markings and in addition there is an ohms scale and one for decibels.  An Anti-parallax mirror permits reading of the knife edge pointer to be made with great precision.

    The meter is supplied complete with a pair of special rubber covered leads which are intended for attachment to the , which may be interchanged to the  Avo meter by means of its captive terminals. The remote ends of the leads are fitted with spring clips which may be interchanged with the AVO Long Reach Safety Clips MK2.

In the case of voltage measurments, wich are more frequently taken than those og current, successive ranges have been closely chosen to obviate the need for taking readings very small deflections.This instrument will produce its highest accuracywhen used face upwards, in which position it has been cali.brated
