ABSTRACT:
This field test instrument serves to home test the horizontal output circuits of television, so as to indicate if the circuit of the set is operating normally. Primarily, it consists of a housing with a circuit, which includes an ammeter, a pair of transistors, a circuit breaker, and a cable with an adapter jack, for placement into horizontal heat sink socket. The instrument further serves to indicate if the set is drawing too much current, and will let the technician know if it is safe to put in a replacement transistor, without having to take the set to the shop for repairs.
