AVO 8 Test Leads, Probes, and Terminals

The AVO 8 has four captive terminals (standing posts), two at the top and two near the base. For basic operation of this meter to measure AC and DC within the switched ranges, connect the test leads to the lower terminals.

Positive Terminal

Connect the red test lead, with the red probe, to the red coloured captive terminal marked "Common Terminal".

Negative Terminal

Connect the black test lead with the black probe, to the black coloured terminal marked "Switched Ranges".

Test Leads and Probes

The nicest design feature of this meter was in the test leads, which were made of soft flexible rubber insulation. All electronic engineers get annoyed when the leads become tangled, and these leads were thoughtfully designed and very easy to untangle.

The AVO "PRODCLIPS" were one of the best features of this meter. They had a thin stem with a push button at the top for operating the jaw. You could tie the jaw to a metal point on the chassis, or even a component lead in inaccessible places. The prod clips were especially useful for attaching the negative terminal to the chassis earth when taking measurements. If you can get a meter with the test leads, and prod clips, then you will have a very useful measuring instrument.

10 kV and 25 kV DC Multipliers

Back in the old days, valve television sets carried high voltages, and as a result, a multiplier used in series with the meter allowed measurements of high voltages. Please consult the instruction manual for more information.
