THE FIRST ANALOG/DIGITAL METER - THE HOYT COMBO SERIES
Hoyt has resolved forever the question of choosing between digital or analog panel meters with the new Combo Series. For the first time, all of the advantages of both 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 ½ 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.

SIGNAL- AND LOOP-POWERED
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, the + and – leads of the input signal. The entire meter, both analog and digital displays, is fully powered by the signal being measured. There are never any grounding or signal- reference questions.

SIGNIFICANT SPACE SAVINGS
Regardless of whether you use analog or digital panels meters now, incorporating Hoyt’s Combo Series will provide a significant space savings in your next application. If you are using analog panel meters now, you can instantly achieve the added benefit of both by upgrading to a Hoyt Combo Series meter. It’s fast, easy, and the two-wire connections allow the Combo Series to upgrade virtually any analog meter application.

MODELS FOR YOUR APPLICATION
Large, bright red LED digital displays are available in Combo Series meters to monitor a wide variety of AC voltage, DC voltage, and frequency ranges. Hour meters are available in the Combo Series with LCD digital displays. With the most popular signals and ranges addressed, Hoyt has a Combo Series meter to meet your specifications.
