AVO CT160 Valve Tester
The instrument will
(I) Check heater continuity.
(2) Measure insulation between electrodes with valve cold.
(3) Measure insulation between electrodes with valve hot.
(4) Measure cathode/heater insulation (for indirectly heated valves).
(5) Rapidly indicate whether a valve is good or bad, use being made of a coloured replace/good scale with mutual conductance as the operative parameter.
(6) Measure the mutual conductance (slope) of a valve, the applied incremental grid voltage being inversely proportional to the “slope” of the valve.
(7) Measure anode current in single and multi-anode valves.
(8) Produce sufficient data to enable static characteristic curves to be plotted on graph paper.
(9) Check rectifiers and diodes under load conditions.
(10) Measure gas current, limited to l00~A.
(11) Measure Screen Current.
The instrument is fitted with an automatic aural and visual warning device which operates if certain circuits within the instrument are inadvertently overloaded by the operator, or if a short occurs upon a valve under test.
The use of specially designed circuits, virtually eliminate the possibility of the valve under test bursting into spurious oscillation.
Power Requirements
The instrument will operate from the following 50 - 500c/s AC supplies:
- 105 - 120V, 175
- 250V. (Adjustment can be made at every 5V.)
Power Consumption
50 watts, maximum.
Physical Data
Weight: 24 lbs. (approx.)
Height: 10 inches
Depth: 11 1/2 inches
Width: 15 1/2 inches
Joint Services Designation
