Analog / Digital Combo Meter from Hoyt Electrical Instrument Works Inc.

Analog and Digital panel meters are combined in one meter. The Combo Series features the same precision analog meter movement you expect from Hoyt, with the addition of a 3 1⁄2 digit, bright red, digital display featuring 0.37" high digits. For all their innovation, the new Combo Series meters are completely compatible with existing analog-only or digital panel meter applications.

With the addition of what amounts to a digital panel meter (DPM) in an analog panel meter case, questions immediately arise regarding input signal and power supply common, ground, "floating", single-ended, or differential inputs. Hoyt resolves these questions too, very simply - the new Combo Series meters are self-powered, 2-wire meters. That means there are only two connections,Ê the + and - leads of the input signal. The entire meter, both analog and digital displays, is fully powered by the signal being measured.
