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.
