Information
The Hickok Electronic Volt-Ohm-Capacity-Mllliammeter,
Model 203PR, is a compact universal test Instrument
which may be used in making measurements in the study
of radio and electrical circuits. It is a versatile
Instrument as the measurement of wide ranges of d.c.
currents, a.c. and d.c. voltages, resistances, capacitances
and inductances may all be made by the one unit. Built
under Hickok high standards of workmanship, It is an
accurate and durable test Instrument.
