Description

Dual-Vue switchboard meters are combination Digital/Analog indicating instruments. They can be configured to accept ACV, ACA, DCV, or DCA input. Both the digital and analog displays can be modified to represent virtually any scaling or engineering units as required. The unit is contained in a 4 1/4” Switchboard housing. It utilizes a taut band moving element and a 0.56”, 3 1/2 digit display for indication (+ or – 1999 counts).
