Default Re: Rescued Test Equipment

The "Capacity Measurer" seems to be an ancient version of a TDR. Distances of up to 1000yds can be measured for cable damage. The ten taught strands act as a calibrated standard & the probe is stroked along them until a measured comparison is obtained. The battery compartment contains a simple buzzer signal source. Then there is the Brown's Earpiece - a null detector ?
