A HOYT 17-B Voltmeter, with high-resistance, movingcoil movement, and a handcalibrated scale, 0-6 volts, marked in red at 3. Two tips are provided at the rear, for insertion in the panel tip-iacks, provided for the purpose in the R. C. A. Radiolas Nos. 20, 25. 26, and 28, and all the similar sets.
A unique construction enables the meter to be turned vertically, horizontally or at any other angle for easy reading, and to fit tip-jacks spaced over a wide range of dimensions. It is truly a universal "tip-in" voltmeter.
Hoyt builds this beautifully finished solid mahogany block with three large binding posts and two tip-jacks. The "Tip-In" Voltmeter fits in these tip-jacks and becomes a two-range table voltmeter for "A" and "B' batteries, and for general testing of circuts in Radio sets. A multiplier in the block gives the B-batterv range of 0-180 volts.
